@mntruell @jonathan_wilke @cursor_ai i can't wait!

@jonathan_wilke @cursor_ai Soon!

I need a @cursor_ai mobile app soooo badly...

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.

Composer 2.5 is a significant step up from Composer 2. This is the very start of our work with SpaceXAI. Hope to have more improvements out soon.

Try it out! (Partially trained on Colossus 2)

LLM psychosis scales with your distance from the code. As a result it tends especially to afflict non-coding managers, PMs, and execs. It’s also a self reinforcing loop. As the code becomes an object of disgust (unreadable pile of vibecoded shit) you are forced to distance yourself further from it and your only interactions with the code are mediated by model.

GPT-5.5 is now available in Cursor! It's currently the top model on CursorBench at 72.8%. We've partnered with OpenAI to offer it for 50% off through May 2.

many such cases…

Rippling AI was the most successful launch we've ever done. On the heels of this launch, Rippling's revenue is now growing 78% YoY (at ARR over $1 Billion). And this growth rate has now increased, every quarter, for three straight quarters.

cooking baby cursor 3.0 with @leerob. there's something you can only feel when it feels real. can't wait to ship a Cursor that's both simple and infinitely powerful.

🧨 Axios only needed to be resolved somewhere in your dependency graph to affect you. Semver + transitive deps + runtime installs = hidden blast radius. If you only checked your project’s lockfile, you may still not know. socket.dev/blog/hidden-bl… #nodejs

love @dougleone !

@gradypb @MollySOShea @dougleone @sequoia love @dougleone !

It's a great day to be a founder: we've named @dougleone chairman of @sequoia. Doug passed the baton a few years back, but he never left: he’s been in the office, working on boards, and serving as consigliere to the next generation. When we realized how much gas Doug has left in the tank, we invited him to ramp back up as an investor at Sequoia. Please cut him some slack as he onboards over the next couple weeks. Let’s go!

when software had a soul there was a moment around 2005 when using a Mac felt like touching something alive. the dock bounced. the genie effect swooped. exposé scattered your windows like cards on a table. none of it was strictly necessary. all of it felt like someone cared – not about metrics, but about the feeling of using a machine. software back then had texture. it had a philosophy. you could feel the person behind it. someone made a decision to make that icon beautiful, to animate that transition just so, to write that error message with a little warmth. apps had personalities. some were weird. some were over-designed in ways that would make a modern PM flinch. but they were alive. the web was the same. personal sites were genuinely personal. blogs felt like letters. forums had regulars. you knew who made what. the internet had neighborhoods, and each one felt different. nothing was optimized for scale. things were made by people who loved what they were making. somewhere along the way, we traded all of that for growth. A/B tests flattened the edges. design systems standardized the personality out. everything got faster, smoother, more consistent – and somehow less interesting. the quirks were removed because they didn't test well. the warmth got cut because it wasn't measurable. we optimized our way into a world of things that work perfectly and feel like nothing. now every app looks the same. every interface follows the same patterns. every product speaks in the same calm, frictionless voice, siloed in their own little islands. the humanity got rounded off. and then came AI agents. and the speed got inhuman. now you can generate an entire product in an afternoon. ship a feature before lunch. spin up ten variations before anyone's had their coffee. the gap from idea to code is basically zero. which sounds incredible. and it is. but there's a catch. when making things are too easy, the slop comes for free too. mediocre things don't look obviously bad – they look fine. they work. they ship. they pass review. and now there are infinite of them. the internet is filling up with software that functions but means nothing. interfaces that are correct but feel dead. products made by agents, reviewed by no one, shipped into the void. this is the thing that keeps me up at night. not that AI will replace people who care. but that it will drown them out. here's what I still believe: the best things are made by people who couldn't help themselves. someone who lost sleep over an icon. who rewrote the same line of copy twelve times. who added an animation nobody asked for because it made the thing feel right. that obsession – that's not inefficiency. that's the whole point. AI doesn't make that irrelevant. it actually makes it rarer and more valuable. taste is not a markdown skill. caring is not a parameter. the weird, specific, "soul" thing you put into something – that can't be programmed into existence. the path forward isn't to make more slop faster. it's to finally give people with real vision the tools to make the thing they always imagined but couldn't build alone. the designer who had the idea but couldn't code. the kid who saw something nobody else saw. the person who cared too much about something most people wouldn't notice. if we get this right, we don't get a faster factory. we get a renaissance. more strange, personal, opinionated software made by teams of people who care and mean it. that's still possible. but only if the people who care get the space and tools to actually express themselves – and don't just hand the wheel to the agent and walk away.

We don’t talk about this enough. Opus scored 20% higher in Cursor than in Claude Code.

Cursor cloud agents can now run on your infrastructure. Get the same cloud agent harness and experience, but keep your code and tool execution entirely in your own network. cursor.com/blog/self-host…
