Congratulations to @HelsingAI on its $1.8B Series E. Helsing is one of the most consequential AI companies in Europe, bringing AI-native software to defense systems. These capabilities strengthen Europe’s deterrence and enable its democratic institutions to flourish. We’re proud to deepen our partnership with @Gundbert, @torstenreil, Niklas Köhler, and the entire team.

"In what world is hurling half an F-35 at somebody an effective way to deter them?" For decades, a single hypersonic missile has cost as much as $50 million. @hargsb built SpaceX's Starshield business before founding @Castelion to make them affordable at scale, and keep America safe.

We're proud to invest in @TeamOratomic's $300M Series A. Oratomic plans to build a fault-tolerant quantum computer by the end of the decade, with a simpler path to quantum error correction built on reconfigurable atomic arrays trapped in focused laser beams. This leap could fundamentally transform our world, unlocking solutions to problems like drug and materials design that are computationally impossible today. Congratulations to @DolevBluvstein and the entire team. cc: @AlexaLiautaud

(1/3) America spends ~$5.3T a year on healthcare and ranks last among peer countries on life expectancy. AI hasn't fixed it, because the wins are isolated tools on a broken whole. We're trying something different at Summa Health, in partnership with @generalcatalyst.

We backed @1001ai_ at seed and are continuing to back the team in their $30M Series A. 1001 builds sovereign AI for the critical infrastructure that moves the physical world: aviation, ports, and energy. It's built and governed locally, so operators stay in control. Congratulations to @b_abughazaleh, Mohammed Fituri, and the entire team.

Today we're announcing our $320M Series A at a $2.3B valuation, led by @khoslaventures , with @generalcatalyst, @JeffBezos , @ericschmidt, @NicoRosberg, alongside leading researchers from frontier labs and academia.

"We are as focused on spatial-temporal dynamics as Anthropic was on code." @gen_intuition's @PimDeWitte explains why the next frontier in AI is teaching models how the physical world unfolds in time. These world models unlock robotics, simulation, and scientific discovery. Congratulations to Pim and the team on their Series A. We’re proud to keep backing them. Revisit @max_rimpel's full conversation with Pim below.

"The fintechs wanted to remove the friction, and hence remove the advisor. But that friction was passed down to the end client." For over a decade, the promise was that tech would replace the financial advisor. Instead, all the complexity and anxiety got handed to the customer. @rronrex founded @arca_wealth to fix that. AI handles the back-office work so advisors can focus on clients and help them reach their full financial potential. We're proud to lead Arca's Series A.

Through its agreement to be acquired by @Qualcomm, @Modular aims to accelerate its mission and real-world impact by empowering developers everywhere with production-grade AI software. Congratulations to @clattner_llvm, @iamtimdavis, and the extended Modular team on their journey to make AI’s compute layer unified, efficient, and accessible to all.

"Even if your sole mission was to make ChatGPT the best model possible for you, your efforts would be pretty much futile. The next generation comes and washes out all the context engineering and sticky notes you prepared." Every AI model starts each conversation from scratch, re-reading the same files and seeing only sticky notes about you and your work. @dan_biderman left academia to build @EngramLab so AI can truly remember your world. We've backed Engram since its first round and are proud to support its $98M launch out of stealth. Congratulations to Dan, @EyubogluSabri, @jxmnop, @realJessyLin, @scott_linderman, Chris Ré, and the Engram team.

"Bad ideas that turn good is where the alpha is." Nearly every investor told @l3amm usage-based billing was a terrible idea, and he built @getmetronome anyway. They saw what others couldn’t at exactly the right time. Metronome became the billing system behind some of the biggest names in AI, and @stripe acquired it earlier this year.

“If the technology that helps us be competitive in manufacturing comes from an adversarial country, we have a serious problem.” @standardbots is building the robots that bring American manufacturing back, designed so any worker can train them.

Today, Ramp raised $750M at a $44B valuation. Last time we grew this fast, we were 1/20th the size. For 2000 years, business was built on two pillars. Today, a third: intelligence. It’s your least governed cost. It’s also your single greatest opportunity.

Martin Scorsese is an advisor to Black Forest Labs. He's spent six decades shaping how the world sees stories. Now he's helping us shape visual intelligence with human taste and craft at the center. We sat down with him for a working storyboarding session using FLUX.

The momentum of @AnthropicAI is generational. Grateful to be part of this journey. Onward.

"There is no truth out there. If the truth is out there, you wouldn't reinvent things or think about things differently." That mindset led @maltekosub and @o_stefan to build @parloa_ai on voice when everyone said chat would change everything, and to turn down $7.7M to keep building.

1/ We’ve raised over $1B at a $26B valuation, led by @Lux_Capital, @generalcatalyst, and @8vc. Our enterprise usage has grown >10x since the start of this year, and our run-rate revenue grew to $492 M. We launched Devin two years ago as the first AI software engineer. Since then, cloud agents have gone from niche to mainstream, and today they are the fastest growing way to create software.
