CryptoPunks creator inks representation deal with major Hollywood talent agency

One of Hollywood’s biggest talent agencies is getting into the NFT game.

Larva Labs, the creator of CryptoPunks, just signed with United Talent Agency (UTA) in a representation deal that will bring one of the earliest and most iconic NFT projects into the entertainment and branding worlds.

“I would say that it is one of the first opportunities for an IP that fully originated in crypto-world to enter a broader entertainment space, and they earned it,” head of UTA Digital Assets Lesley Silverman told The Hollywood Reporter. “They really have hit the zeitgeist in a tremendous way.”

The deal could see CryptoPunks popping up across film, TV, video games and other licensing areas. Larva Labs’ other art projects, Meebits and Autoglyphs, will also be represented by UTA moving forward. The terms of the deal weren’t disclosed.

As speculative investment in NFTs explodes, CryptoPunks remain one of the most recognizable — and valuable — pioneers in the space. Larva Labs launched 10,000 of the individual algorithmically-generated pixelated figures on the Ethereum blockchain back in 2017.

To the untrained eye, and arguably to the trained eye too, CryptoPunks are just little pixelated portraits of different characters, some wearing pirate hats, others in aviator glasses smoking pipes. But to the crypto world, punks are a social signifier, communicating early investment into NFTs, personal style and, importantly, wealth.

The value of CryptoPunks skyrocketed from zero (they were initially given away for free) and now even the least expensive collectible punks run for hundreds of thousands of dollars, with the most valuable selling for millions. In May, a bundle of nine CryptoPunks sold for just under $17 million in an auction run by Christie’s. And last week, even Visa got in the game, spending $150,000 on CryptoPunk #7610, a digital illustration sporting a mohawk and green face makeup.

It’s noteworthy that a traditional talent agency best known for representing A-list celebrities is getting into the NFT game, but it’s not the group’s first time getting its feet wet in the wild world of crypto. Earlier this month, UTA signed a company called Rally that runs a platform that helps creators issue branded social tokens that fans can spend on merch and exclusive content.

LinkedIn is scrapping its Stories feature to work on short-form video

What do LinkedIn and Twitter have in common? They both introduced ephemeral story features that were pretty fleeting. LinkedIn announced today that it will suspend its Stories feature on September 30 and begin working on a different way to add short-form videos to the platform.

LinkedIn announced the upcoming change to warn advertisers who might have already purchased ads that would run in between Stories. Those will instead be shared on the LinkedIn feed, but users who promoted or sponsored Stores directly from their page will need to remake them.

LinkedIn introduced Stories in September, around the same time that Twitter rolled out Fleets to all users before doing away with the feature. This was part of a larger web and mobile redesign, which also added integrations with Zoom, BlueJeans and Teams to help professionals stay connected while working from home. But according to LinkedIn, these temporary posts didn’t quite work on the platform.

“In developing Stories, we assumed people wouldn’t want informal videos attached to their profile, and that ephemerality would reduce barriers that people feel about posting,” wrote LinkedIn’s Senior Director of Product Liz Li in a blog post today. “Turns out, you want to create lasting videos that tell your professional story in a more personal way and that showcase both your personality and expertise.”

Li also noted that users want “more creative tools to make engaging videos.” While Stories included stickers and prompts, users wanted more creative functionality.

If LinkedIn is successful in its plans to create a short-form video feature, it would join platforms like Snapchat and Instagram that have built their own TikTok-like feeds. Sure, most users probably don’t post the same content on LinkedIn and their personal social media accounts, but there actually are some prominent TikTokers sharing career advice, interview tips, and resume guidance, so LinkedIn’s pivot to video might not be as weird as it seems.

Introduction to Ansible

I’ve worked in IT for a long time, and my secret collection of shell and Python scripts has made a lot that works easier. I remember having a repository full of scripts to install this, automate that… you get the idea. Some of these have been my pride and joy, full of witty remarks, inside jokes, and pop culture references. And I’ve handed these down to teams that succeeded me with pride. But these DIY Adhoc scripts don’t scale well, and often cause more trouble than they’re worth.

Ansible is the tool to solve these problems. It’s a collection of several (hundred?) modules to do most of what you can imagine doing as a sysadmin/troubleshooter. You can assemble these modules into Playbooks and use them for Adhoc maintenance or reliable production use-cases. Say you need to set up a new Linux machine with Apache installed. In bash, you would write the installation commands one by one. But in Ansible, you can create a task for what you want and let Ansible take care of the rest. That’s the key difference: moving from how to what. With Ansible, you define the final state of your system and Ansible manages the execution - this is the difference between declarative and imperative.

Software Project Misconceptions: More People Will Finish Sooner

Introduction

More hands will finish sooner. This is common sense that has been applied successfully in many human endeavors, throughout centuries, industries, and civilizations. A practice so popular that can easily result in a misconception due to hidden assumptions, oversimplification, and bias. Employing more people to finish your software project sooner is not always a good idea. Writing code can be a more complex and complicated activity than simple procedural and repetitive work. Using a large employee expansion as a strategy to solve your software project's problems is like testing only a single happy path for a use case with many negative tests and edge cases.

Software Code as a Medium

Software code is a tractable medium. From simple ideas, we can build concepts like objects, interfaces, and behavior into flexible representations of complete systems. Although it's reasonable to assume that this medium tractability will lead to fewer difficulties, coding introduces its own difficulties. Conceptually involved ideas with problematically complex implementation, especially under scaled codebases (e.g., millions of lines of code) require creativity, skills, quality, training, communication, and coordination among employees.

Cheeterz Club wants to make reading glasses hip

Can reading glasses actually be cool? A new eyewear company called Cheeterz Club thinks so. The startup is working to change the perception of reading glasses from being just cheap, disposable items you pick up from a rotating display rack at your local drug store to being something you’d actually be proud to wear. To do so, the company is designing its glasses with quality lenses and frames in range of styles, while still keeping the pricing affordable.

The startup — whose name is a reference to the slang term for glasses, “cheaters,” — was founded by Jennifer Farrelly, whose background includes work in advertising and sales at companies like Uber and Virool.

She said the idea to make a better set of readers came to her because she found herself frustrated by the current options on the market.

“It all started a few years ago. My friends were posting on social media these really depressing comments and posts like: ‘I’m old and turning into my parents, this is awful.’ And I [thought to myself] why does it have to be like that? I feel just as young today as I did ten years ago,” Farrelly explains. “Why are my friends and I feeling forced to feel old because of something that happens overnight?,” she says, of what felt like the sudden onset of middle age and the hardships it brings.

What’s worse, Farrelly says, is that when you finally make your way to the drugstore to pick out some reading glasses, all you’ll find are bad, plastic pairs that both look and feel cheap.

“That’s even more demoralizing,” she adds.

OLYMPUS DIGITAL CAMERA

So Farrelly teamed up with a former Warby Parker and Pair Eyewear Head of Product, Lee Zaro, to design a new line of more fashion-forward eyewear.

Zaro, who’s based in the L.A. area, immediately saw the opportunity.

“Drugstore reading glasses are typically poor in quality, and can feel like they are designed with our parents in mind, leaving a huge unmet need for sophisticated eyewear options,” he said. “When Jennifer approached me to help design her first line of eyewear, I knew it was a brilliant idea.”

To differentiate itself from lower-end readers, Cheeterz Club glasses are made with 100% acetate and feature spring hinges and stainless steel. The lenses, meanwhile, offer more clarity than is often found in reading glasses.

Typically, ophthalmic plastic lens materials have an Abbe value — a measure of the degree at which light is dispersed or separated — between 30 and 58. The higher number offers better optical performance. Crown glass can have an Abbe value as high as 59, but polycarbonate readers (like those from Warby Parker, Farrelly notes) would have an Abbe value of 30. Cheeterz Club lenses, which are CR-39 lenses, are at at 58. This is a difference you can tell when trying the glasses on alongside your drugstore readers.

Cheeterz’ lenses also offer 100% UVA/UVB protection, and are oil and water repellent. They can optionally be bought in one of eight fashion tints, from pink to blue, or in two sun shades. Consumers can also opt to add Blue Light coating to help with screen-induced eye fatigue or they can choose Progressive lenses, which combine distance vision with a reading lens.

Tints are an extra $10, Blue Light protection is $25, and Progressive lenses are $40.99 — lower than market rates.

At launch, Cheeterz Club offers 14 different styles ranging from traditional to the more modern, starting at $28.99.

Farrelly says finding the right price was key, because unlike regular glasses, consumers often buy multiple pairs of readers to leave around the house or car, pack in purses and bags, and so on.

“If I break something that costs me a couple $100, I’d be really upset about it,” she says. “But at a drugstore price of under $30, I can have them in all sorts of colors and different tints.”

For Farrelly, making the startup a success goes beyond brining higher-quality reading glasses to market. It’s also about serving a demographic that often gets overlooked.

“Founders in their forties do not get representation, and it’s unfortunate. And there are also people in their forties and fifties that have disposable income and are looking for cute things. They’re spending so much money on facial creams and Botox,” she says, “but then you’re forced to put this really ugly pair of glasses on your face that make you feel bad about yourself.”

While Cheeterz Club today is selling direct to the consumer, the company is talking to eye doctors, boutiques and others who may eventually resell for them, as more of a B2B model. It’s also testing selling on Amazon with one pair of Blue Light glasses.

Cheeterz Club plans to start discussing fundraising with seed investors later this fall.

A popular smart home security system can be remotely disarmed, researchers say

A cybersecurity company says a popular smart home security system has a pair of vulnerabilities that can be exploited to disarm the system altogether.

Rapid7 found the vulnerabilities in the Fortress S03, a home security system that relies on Wi-Fi to connect cameras, motion sensors, and sirens to the internet, allowing owners to remotely monitor their home anywhere with a mobile app. The security system also uses a radio-controlled key fob to let homeowners arm or disarm their house from outside their front door.

But the cybersecurity company said the vulnerabilities include an unauthenticated API and an unencrypted radio signal that can be easily intercepted.

Rapid7 revealed details of the two vulnerabilities on Tuesday after not hearing from Fortress in three months, the standard window of time that security researchers give to companies to fix bugs before details are made public. Rapid7 said its only acknowledgment of its email was when Fortress closed its support ticket a week later without commenting.

Fortress owner Michael Hofeditz opened but did not respond to several emails sent by TechCrunch with an email open tracker. An email from Bottone Riling, a Massachusetts law firm representing Fortress, called the claims “false, purposely misleading and defamatory,” but did not provide specifics that it claims are false, or if Fortress has mitigated the vulnerabilities.

Rapid7 said that Fortress’ unauthenticated API can be remotely queried over the internet without the server checking if the request is legitimate. The researchers said by knowing a homeowner’s email address, the server would return the device’s unique IMEI, which in turn could be used to remotely disarm the system.

The other flaw takes advantage of the unencrypted radio signals sent between the security system and the homeowner’s key fob. That allowed Rapid7 to capture and replay the signals for “arm” and “disarm” because the radio waves weren’t scrambled properly.

Vishwakarma said homeowners could add a plus-tagged email address with a long, unique string of letters and numbers in place of a password as a stand-in for a password. But there was little for homeowners to do for the radio signal bug until Fortress addresses it.

Fortress has not said if it has fixed or plans to fix the vulnerabilities. It’s not clear if Fortress is able to fix the vulnerabilities without replacing the hardware. It’s not known if Fortress builds the device itself or buys the hardware from another manufacturer.

UK-based Heroes raises $200M to buy up more Amazon merchants for its roll-up play

Heroes, one of the new wave of startups aiming to build big e-commerce businesses by buying up smaller third-party merchants on Amazon’s Marketplace, has raised another big round of funding to double down on that strategy. The London startup has picked up $200 million, money that it will mainly be using to snap up more merchants. Existing brands in its portfolio cover categories like baby, pets, sports, personal health and home and garden categories — some of them, like PremiumCare dog chews, the Onco baby car mirror, gardening tool brand Davaon and wooden foot massager roller Theraflow, category best-sellers — and the plan is to continue building up all of these verticals.

Crayhill Capital Management, a fund based out of New York, is providing the funding, and Riccardo Bruni — who co-founded the company with twin brother Alessio and third brother Giancarlo — said that the bulk of it will be going towards making acquisitions, and is therefore coming in the form of debt.

Raising debt rather than equity at this point is pretty standard for companies like Heroes. Heroes itself is pretty young: it launched less than a year ago, in November 2020, with $65 million in funding, a round comprised of both equity and debt. Other investors in the startup include 360 Capital, Fuel Ventures and Upper 90.

Heroes is playing in what is rapidly becoming a very crowded field. Not only are there are tens of thousands of businesses leveraging Amazon’s extensive fulfillment network to sell goods on the e-commerce giant’s Marketplace; but some days it seems we are also rapidly approaching a state of nearly as many startups launching to consolidate these third-party sellers.

Many a roll-up play follows a similar playbook, which goes like this: Amazon provides the Marketplace to sell goods to consumers, and the infrastructure to fulfill those orders, by way of Fulfillment By Amazon and its Prime service. Meanwhile, the roll-up business — in this case Heroes — buys up a number of the stronger companies leveraging FBA and the Marketplace. Then, by consolidating them into a single tech platform that they have built, Heroes creates better economies of scale around better and more efficient supply chains, sharper machine learning and marketing and data analytics technology, and new growth strategies. 

What is notable about Heroes, though — apart from the fact that it’s the first roll-up player to come out of the UK, and continues to be one of the bigger players in Europe — is that it doesn’t believe that the technology plays as important a role as having a solid relationship with the companies it’s targeting, key given that now the top Marketplace sellers are likely being feted by a number of companies as acquisition targets.

“The tech is very important,” said Alessio in an interview. “It helps us build robust processes that tie all the systems together across multiple brands and marketplaces. But what we have is very different from a SaaS business. We are not building an app, and tech is not the core of what we do. From the acquisitions side, we believe that human interactions ultimately win. We don’t think tech can replace a strong acquisition process.”

Image Credits: Heroes

Heroes’ three founder-brothers (two of them, Riccardo and Alessio, pictured above) have worked across a number of investment, finance and operational roles (the CVs include Merrill Lynch, EQT Ventures, Perella Weinberg Partners, Lazada, Nomura and Liberty Global) and they say there have been strong signs so far of its strategy working: of the brands that it has acquired since launching in November, they claim business (sales) has grown five-fold.

Collectively, the roll-up startups are raising hundreds of millions of dollars to fuel these efforts. Other recent hopefuls that have announced funding this year include Suma Brands ($150 million); Elevate Brands ($250 million); Perch ($775 million); factory14 ($200 million); Thrasio (currently probably the biggest of them all in terms of reach and money raised and ambitions), HeydayThe Razor GroupBrandedSellerXBerlin Brands Group (X2), Benitago, Latin America’s Valoreo and Rainforest and Una Brands out of Asia. 

The picture that is emerging across many of these operations is that many of these companies, Heroes included, do not try to make their particular approaches particularly more distinctive than those of their competitors, simply because — with nearly 10 million third-party sellers today on Amazon globally — the opportunity is likely big enough for all of them, and more, not least because of current market dynamics.

“It’s no secret that we were inspired by Thrasio and others,” Riccardo said. “Combined with Covid-19, there has been a massive acceleration of e-commerce across the continent.” It was that, plus the realization that the three brothers had the right e-commerce, fundraising and investment skills between them, that made them see what was a “perfect storm” to tackle the opportunity, he continued. “So that is why we jumped into it.”

In the case of Heroes, while the majority of the funding will be used for acquisitions, it’s also planning to double headcount from its current 70 employees before the end of this year with a focus on operational experts to help run their acquired businesses.

Whoop raises another $200M for its athlete-focused fitness wearable

Founded in 2012, Whoop is far from a household name in the world of fitness trackers. But over the years, the company has attracted its share of converts. It hasn’t had any issue attracting venture capital over the years, either. Last time we checked in on the Boston-based company was in late-2019, when it raised $55 million. Now it’s back with a massive $200 million raise.

The Series F round brings Whoop’s total funding to nearly $405 million — a pretty massive investment for a company of its size. The round, led by SoftBank’s Vision Fund 2, puts the valuation at a jaw-dropping $3.6 billion valuation.

Additional investors include IVP, Cavu Venture Partners, Thursday Ventures, GP Bullhound, Accomplice, NextView Ventures and Animal Capital. They join a long list of former backers, including the National Football League Players Association, Jack Dorsey and a number of professional athletes.

The company’s targeting of athletes marks a strong contrast with leading consumer wearables like the Apple Watch and Fitbit. In fact, the company has a specific offering for sports teams, as well as solutions for businesses, healthcare and government/defense.

Whoop’s name made the rounds recently when Fitbit announced a “Daily Readiness Score” for the Charge 5, which many likened to the company’s more advanced analytics.

The company cites “rapid growth” in its membership offering over the past year as a motivation behind seeking additional funding. That was likely driven, in part, by the decision in 2019 to make the $500 wearable free, while focusing on a subscription service that starts at $18 a month for an 18-month membership (the shorter the membership, the more the monthly fee).

Whoop is eying international expansion beyond the U.S. and using the massive influx of cash on R&D for its hardware, software and analytics solutions. Money will also go toward expanding headcount, which is currently in excess of 500 (with nearly half of those employees having joined in the past year).

“We are thrilled to deepen our partnership with SoftBank as we grow internationally,” founder and CEO Will Ahmed said in a release. “While we have experienced amazing growth in the past year, the potential of our technology and the vast market for health monitoring remains largely untapped.”

Challenger bank Bunq rolls out Spanish IBANs

Amsterdam-based challenger bank Bunq is updating its service with a handful of new features. In addition to Dutch, German and French bank account numbers, existing and new users in Spain can now get a Spanish IBAN.

European IBANs are supposed to work across Europe. Your employer or internet provider can’t force you to get a local IBAN. And yet, that’s rarely the case. When you move to another European country, chances are the first thing you do is that you open a local bank account.

While European fintech companies have teamed up to create a lobbying effort called ‘Accept my IBAN’, some challenger banks, such as Bunq, are adding the ability to get local bank account numbers as an intermediary fix. Bunq users can also choose to associate IBANs from multiple European countries with their account. You have to pay a one-time fee of €9.99 every time you add a new local IBAN.

Bunq is also drawing inspiration from Revolut, Wise, Vivid Money and others as you’ll soon be able to receive, convert and hold other currencies. For instance, if you’re going to a non-Euro country for an internship, you will be able to receive your salary on your Bunq account. Bunq is starting with USD accounts with plans to add more currencies down the road.

Other new features include the ability to receive reminders the day before a direct debit occurs, a subscription view that lets you view current subscriptions and when they’re set to expire, an improved search feature and the ability to automatically accept direct debits and payment requests from your friends — make sure you set up a limit before enabling that feature.

Bunq recently announced plans to raise $228 million (€193 million) at a $1.9 billion valuation (€1.6 billion). The investment round hasn’t been approved by the Netherlands’ banking regulator just yet. Bunq is currently operating in 29 European markets and has more than €&billion in user deposits.

Taming the Moose: Method Modifiers Instead of Overrides in Object-Oriented Perl

Last month I wrote about using Moose's override function to, well, override a superclass's method. Chris Prather on the #moose IRC channel suggested soon after that the around method modifier (or its little sisters before and after) might be a better choice if you're also calling the original method inside. He noted that "at a minimum override only works if you're subclassing, around will apply to composing methods too."

His point was that when you decide to compose roles (also know as traits) instead of or in addition to more traditional inheritance, override simply doesn't work: only a method modifier will do. (And as Graham Knop and Karen Etheridge later remarked on IRC, override isn't even an option if you're using Moo as an alternative to Moose.)

Containers on AWS: Which Service Is Right for Your Workload

Due to their lightweight, portable nature, using containers allows optimal cloud-native application builds. Now, running ten containers is relatively straightforward, but when you consider running containers at scale - hundreds and thousands of containers comprising hundreds of services, for example -  this can get out of hand quickly. 

At this point, enterprises reach for a service or tool that can handle this challenge, which is where container orchestration tools come into the picture. Since 2014, AWS has launched more than 50 new features and multiple services to help engineers run containers in the cloud. At first, these tools aimed at optimizing how to run containers. The evolution of that tech has moved towards granular management and orchestration of container workloads.

Tiger Global in talks to make Apna India’s fastest unicorn

Apna, a 21-month-old startup that is helping millions of blue and gray-collar workers in India upskill themselves, find communities and land jobs, is inching closer to becoming the fastest tech firm in the world’s second largest internet market to become a unicorn.

Tiger Global is in advanced stages of talks to lead a $100 million round in Apna, according to four sources familiar with the matter. The proposed terms value the startup at over $1 billion, the sources said.

The round hasn’t closed yet so terms of the deal may change, some of the sources cautioned.

If the round materializes, Apna will become the youngest Indian startup to attain the much coveted unicorn status. The startup, which launched its app in December 2019, was valued at $570 million in its Series B financing round in June this year. It will also be the third financing round Apna would have secured in a span of less than seven months.

Tiger Global, an existing investor in Apna, didn’t respond to a request for comment earlier this month. Apna founder and chief executive Nirmit Parikh, an Apple alum, declined to comment on Tuesday.

Indian cities are home to hundreds of millions of low-skilled workers who hail from villages in search of work. Many of them have lost their jobs amid the coronavirus pandemic that has slowed several economic activities in the world’s second-largest internet market.

Apna, whose name is inspired from a 2019 Bollywood song, is building a scalable networking infrastructure so that these workers can connect to the right employers and secure jobs. On its eponymous Android app, users also upskill themselves, review their interview skills, and become eligible for more jobs.

As of June this year, Apna had amassed over 10 million users and was facilitating more than 15 million job interviews each month. All jobs listed on the Apna platform are verified by the startup and free of cost for the candidates.

The startup has also partnered with some of India’s leading public and private organizations and is providing support to the Ministry of Minority Affairs of India, National Skill Development Corporation and UNICEF YuWaah to provide better skilling and job opportunities to candidates.

The investment talks further illustrates Tiger Global’s growing interest in India. The New York-headquartered firm has made several high-profile investments in India including in BharatPe, Gupshup, DealShare, Classplus, Urban Company, Coinswitch Kuber, and Groww.

More than two dozen Indian startups have become a unicorn this year, up from 11 last year, as several high-profile investors including Tiger Global, SoftBank, and Falcon Edge have increased the pace of their investments in the world’s second most populous nation.
