Dubbed Really Simple Licensing (RSL), companies like Medium, Yahoo, and Reddit have signed up to participate. The concept includes automated licensing, a method to charge fees for access to materials, and, critically, solidarity. RSL joins Cloudflare’s Pay Per Crawl system and the work of TWiST500 startups like TollBit, Human Native, and Created by Humans in the fight to carve off a piece of AI revenues for the websites that make those incomes possible. Bending Spoons buys Vimeo: Bending Spoons, an Italian Internet holding company, will purchase online video service Vimeo for $1.38 billion in an all-cash deal. Shares of Vimeo shot 60% higher to $7.75 today, just under the $7.85 that the acquirer intends to pay. TechCrunch notes that other companies that Bending Spoons purchased have seen dramatic staff and capacity cuts after their absorption. Vimeo posted $105 million in total Q2 revenue per its most recent earnings report, flat year-over-year. More capital for quantum: Flush with $1 billion worth of new funding, quantum computing startup PsiQuantum wants to build the first “commercially useful, fault-tolerant quantum computers,” it says. The Journal reports that PsiQuantum could have a commercial-grade quantum computer in market by 2027, far faster than some industry participants anticipated. PsiQuantum is not alone in raising new capital this year, with fellow quantum-focused startup Quantinuum raising hundreds of millions of dollars just weeks ago. TWiST500 Bon voyage, Klarna. Today, shares of the Swedish buy now, pay later company began to trade. After pricing its IPO at $40 per share last night, the well-known unicorn appreciated by about 17% at the time of writing to $47.05 per share. After targeting a lower range, Klarna was worth just over $15 billion at its IPO price and is now worth around $17 billion, per our back-of-the-envelope math. That’s a far cry from its highest private-market valuation set in 2021, but it's a near treble its later, lower price tag that it raised after the tech market settled down. We don’t keep companies that have exited on the TWiST500, so off it will come. Well done, Klarna! Elsewhere in TWiST500-land, Replit announced today that it raised a new $250 million round, bringing its total worth to $3 billion. The company helps turn user ideas “into apps,” it says, a project that pushed its revenue from the single-digit millions to $150 million in the last year, per Bloomberg reporting. TWIST interviewed Replit CEO Amjad Masad on episode 2099, which you can listen to here. While Replit may be best known for its work in the ‘vibe coding’ space, it has far bigger aspirations. It launched a new AI agent today it calls ‘Agent 3,’ which it claims has a 10x increase in autonomy, thanks to an ability for Agent 3 to work longer by itself. And, it can both test and improve code that it writes. — AlexA message from Lemon.io Hire pre-vetted remote developers and get 15% off your first 4 weeks of developer time at https://Lemon.io/twistThis Week in StartupsE2175 : Alex digs into the real-world rollout of AI agents: Paid.ai’s Manny Medina explains agent economics and value-based pricing.
