Today is a big day for @SocketSecurity. We just raised a $60M Series C at a $1B valuation, led by @ThriveCapital with participation from @a16z, @AbstractVC, and @CapitalOne Ventures. Total funding is now $125M. Four years ago, we started Socket because open source dependencies were flowing into production faster than anyone could vet them. AI has massively accelerated that. Code is being written, shipped, and deployed before any human reads it. Security has to operate at that same speed. One data point from Thrive's diligence that I keep coming back to: they first discovered Socket because @cursor_ai, @OpenAI, and @AnthropicAI all independently told them it was the most important security tool they'd adopted for AI-driven development. Three of the most sophisticated AI companies converging on the same vendor unprompted. Since our Series B, Socket has grown to more than 20,000 organizations, protecting over 1.5 million repositories and blocking more than 1,000 supply chain attacks every week. The team is now over 100 people. Three out of five FAANG companies are Socket customers. So are the companies building the most ambitious AI products: @AnthropicAI, @cursor_ai, @xai, @figma, @vercel, @Replit, @scale_AI, @GustoHQ, @Mercadolibre, and @cribl_io, alongside Fortune 100s in financial services and global media. What we've shipped since the last round: • Socket Firewall blocks malicious packages at install time, before they reach a developer's laptop or CI pipeline. Free for everyone. • Reachability analysis via our acquisition of Coana, eliminating 50-80% of irrelevant vulnerability alerts by focusing only on CVEs that are actually exploitable. • Socket Certified Patches for remediating exploitable CVEs in seconds without waiting on upstream maintainers. • Coverage extending to browser extensions, editor extensions, MCP servers, and AI tools via our acquisition of @secureannex. When the Axios compromise hit, our detection systems flagged the malicious dependency within six minutes. Within 24 hours, more than 2,000 organizations onboarded to Socket to block it. Where the funding goes: deeper investment in Firewall, massively expanding Certified Patches, moving protection closer to every point of install across the developer toolchain, and new product launches pushing Socket into a category we haven't entered before. We're hiring across engineering, sales, customer success, and threat intel. ❤️ Thank you to our customers, investors, and the open-source community for your support. Together, we’re making software safer for everyone.

Very excited to bring Dileep onto the team as our Head of AI. With him and Doris, we have two incredible minds going after both sides of the same question: how does intelligence arise in the brain, and can we use that to build safe AGI? If you want to investigate what's missing from current approaches and help build something better - we're hiring: astera.org/careers/

1/ We're sharpening Astera's focus to two areas—intelligence (biological and artificial) and AI-enabled life sciences—and restructuring to go deeper on both. Over five years Astera has tested different approaches to funding and building ambitious technical work. The biggest takeaway: the more focused we are, the better the work gets. We're now separating Astera's foundation from the technical divisions it supports, each run by leaders with deep expertise and real authority to move fast. More to come soon on the people joining and programs launching to drive this work forward. Details below.

We've selected @vast for the sixth private astronaut mission to the @Space_Station, targeted for no earlier than summer 2027—the company's first selection to the orbiting laboratory. Read more: go.nasa.gov/4rLsSfw

Vast's first crewed mission coming up!

Went to see a commercial space station being built @vast, and it was quite glorious. Full episode coming on the YouTube channel soon

Haven Demo has successfully completed its initial perigee-lowering maneuver to demonstrate the spacecraft's ability to perform a controlled deorbit. The spacecraft engaged its orbit-maneuvering thrusters for approximately 14 minutes, lowering perigee by ~170km.

We’re looking for a COO for Astera Neuro! This is an all-hands-on-deck effort as we build a new paradigm for systems neuroscience, and the COO role is going to be critical. You’re: unconventional, wildly driven, 1000% mission-aligned, love management and organizational challenges, and care deeply about neuroscience/neurotech/AI/consciousness. Age and pedigree do not matter. This should be your dream job.
