Is the old cybersecurity model breaking? Our partner @shardul_shah joined @RebeccaBellan on @TechCrunch’s Equity podcast to discuss the permanent, resilient need for cybersecurity, and how enterprises should be thinking about it in the AI era.

Is the next era of cybersecurity machine vs. machine? @shardul_shah of @IndexVentures tells @EquityPod that as AI-powered attacks get faster and cheaper, human-in-the-loop defense won’t be enough. The result could be an entirely new security stack.

Today I'm excited to share that @usefootprint has raised a $25M Series B, bringing our total funding to $45M. Financial institutions are in an arms race with cartels and oligarchs. The movement of illicit money globally has grown by $1.3 trillion since 2023, now sitting at $4.4 trillion. And bad actors have taken full advantage of AI’s capabilities: generating fake identities and shell companies faster than any team can manually review. Yet, the work to combat financial crimes is still being done the old way - risk teams sifting through spreadsheets, PDFs, and disconnected tools one case at a time. AI lets us reimagine this sector. We're solving for this at @usefootprint by focusing on two things: time and memory. → Time: Percy runs your compliance program end-to-end in 1/10th the time, so your institution has extra eyes on every case, and your human analysts dedicate their time to the ones that truly matter. → Memory: Trust Fabric makes sure the grey area is removed and learnings are universal so your team (whether 5 or 500 people) catches more true positives and identifies fraud rings before they form. With this raise, we're doubling down on the thesis that risk operations will be re-envisioned for the AI-native era. As AI increases financial crime in the global economy, we're building the defense system that can expand to meet and defeat it. We're honored @QEDInvestors doubled down on their conviction, leading our Series B two years after leading our Series A. The same goes for those who have invested since day one: @lererhippeau, @indexventures, @BoxGroup, Operator Partners, Definition, and @animalcapitalco. And for new investors @am_mufg_jp, @commercevc, @lightbank, and @alumniventures. To the Footprint team: this company would be nowhere without your belief in building a digital world full of trust. I thank you from the bottom of my heart for being on this journey with us. To our customers: thank you for trusting us with your most important decisions. Your partnership is helping us build a better future for financial crime compliance. Full story on our blog:

Two years ago, Chris Ellis and Adam Stevenson sold us on their vision of replacing one-size-fits all group plans with individual health budgets. With 5K+ employers now using @thatch_ai, we’re excited to partner again as they announce their $108M Series C!
Show more
Today, we're announcing @thatch_ai raised a $108M Series C at a $1B valuation from @thegp, @IndexVentures, @generalcatalyst, @a16z. The idea we're betting on: healthcare serves whoever controls the dollar. For 80 years that's been the employer. We think it should be you. Employers typically choose one health plan for everyone. We think there's a better model: give people a health budget and let them choose the insurance and care that fits their life. That is the idea behind Thatch. ARR has grown nearly 7x in the last twelve months, and more than 5,000 employers now use Thatch. None of this happens without our team, or without the employers who believe that their people know what their families need better than they ever could. We're building a healthcare system people love by changing how we fund it.

We've raised €20M led by @IndexVentures, joined by @villigm (Bolt), @danieldines (UiPath) and @tom_okman (Nord Security). @nomosenergy is a full-stack power company. We connect home batteries, EVs, heat pumps and solar to the energy market, providing flexibility to Europe's electricity system. We run the energy business of category-leading OEMs and asset installers to lower household electricity costs, balance the grid and restore Europe's competitiveness. Because Europe's energy is Europe's power. Power to you.

Built by DeepMind alumni, British AI lab Inherent released Faraday, an AI agent whose ability to replicate scientific papers could be a stepping stone for innovation.
Just one day after setting up Revel, an intern at @OrbitalOps_ was already using it to independently run 40 hot-fires. Orbital Operations is developing a high-delta-V, high-thrust rocket vehicle around a first-of-its-kind cryogenic propellant management system to unlock rapid mobility across LEO, GEO, and beyond. Fresh out of @ycombinator Combinator W25, their small team—half of them interns—needed test software that could move as fast as they did. Before Revel, Orbital Ops had never run a test. They had no data recording, no automated sequencing, and no software team to build either. With Revel, they now: • Run dozens of tests in a day • Give interns ownership of entire engine subsystems • Operate five-plus test cells daily, up from a single test cart All without a single software hire. Thanks to @BenSchleuniger, Ross Doherty, @nicosuave9, Dane Patten, @stefan_salaices, and the rest of the Orbital Ops team for the partnership. Link to the full case study in the replies.

Today, we're introducing @Intelligence_ai. In 6 months, as a team of 10, we scaled from $5M to $60M ARR and 5.5M users across 190+ countries. We raised a $7.9M seed, led by @IndexVentures with participation from @conviction, @A_StarVC, and @combinator to build DesignArena, a universal interface for accessing and evaluating the world's AI capabilities. Most evaluations try to simulate the real-world. We believe the real-world is the ultimate verifier. People come to @DesignArena with a request. Models compete to fulfill the request, and users determine what works best for them. Their live user behavior evaluates the models, improves how work is routed, and helps people access the right intelligence. We've helped the world's leading frontier labs break the news on their SOTA capabilities. What's the limit? Join us and find out.

Five months ago, we launched @simile_ai with the belief that simulation would become a new way for the world to make decisions. Today, that belief feels less like a thesis and more like the beginning of a new category. Incredibly proud of my team. We are just getting started.

Exclusive: Inside $3.8B @chaidiscovery After leaving OpenAI & Stripe, co-founders Josh Meier (@joshim5) and Jack Dent (@jackdent) built a pioneering AI drug design model called Chai-1. Now? Their models are used by giants like Eli Lilly, Pfizer and Novartis. Their models design antibodies in hours, not years - with atomic-level accuracy confirmed in the lab. If they're right, we're closer than ever to curing complex diseases. We went to San Francisco to find out. They've raised $600M + from @saranormous @lachygroom @FEhrsam @ThriveCapital @sequoia @generalcatalyst @OpenAI @MenloVentures @IndexVentures @kleinerperkins + more. 0:00 AI drug design - how is it possible? 1:32 Josh: Leaving OpenAI for biology 2:34 90% of drugs used to fail 3:24 An outside scientist's honest take 4:40 Chai-3: Drug design in hours not years 5:30 Why Eli Lilly bet on Chai 6:20 When will this reach patients? 8:56 A hopeful future: Alzheimer's & aging
