As agents write more code, automated verification becomes one of the most critical layers in the stack.
Huge congrats to @e2e_inc on the rebrand and $8M seed round. Proud to back the vision!

Congratulations team @manicule! 🚀
We just raised $1.3M from @ycombinator and @BroomVentures to build AgentRel.
We help devtools with:
- Discoverability: does ChatGPT, Claude, or Gemini recommend you or your competitor?
- Usability: where does Claude Code struggle with your product?
Profound, Peec, and most other AI visibility tools just measure noise, really. Every serious marketer knows this, and these companies know it too.
We do the opposite: we give you accurate data and help you act on it.
Reply with your brand name, and I'll set you up with a Pro workspace for free.
Most investors show up on Demo Day. We're already done by then.
Our founder Ravi Chachra joined @HiJoJoPartners to unpack our pre-Demo Day thesis, the AI cycle, and lessons from recent YC batches. 🎧

YC works with thousands of founders every year, which gives us an early look at how startups are changing. Right now, the shift is striking: startups are moving from bits to atoms, nearly one in five YC companies has a solo founder, and companies are reaching meaningful revenue faster than ever.
In this episode of the Lightcone, @garrytan, @snowmaker, @sdianahu, and @harjtaggar dig into what’s driving these changes and what they mean for founders.
They discuss how AI is making it possible for smaller teams to take on more ambitious problems, why experienced founders are having a resurgence, and why knowing what to build is becoming more important than simply knowing how to build it.

Incredible milestone for the @Better_Auth team joining forces with @vercel!
Open-source, framework-agnostic auth entering the agent era is a powerhouse combination.
Proud to have backed the team from early on. Huge congratulations! 🚀
Better Auth is joining Vercel.
Vercel shares our commitment to keeping auth open source, framework and platform agnostic. Joining forces gives us more resources and room to focus on building the framework that much of the community relies on.
Together, we’ll also be able to invest more deeply in where auth is heading: a future where agents act on users’ behalf and need secure, scoped, and revocable access.
Congratulations to the @starslingdev team on the $3M raise!
Excited to partner up for what’s ahead! 🙌🏻
Today we’re announcing our pre-seed round and a new product: @starslingdev Review Runners - code review agents that use your model key, your team’s skills and scripts, and reviewers you define, all running in GitHub Actions.
We’ve raised $3M from @BessemerVP and @ycombinator to make code verification agent-native.
code → verification (ci + code review) → production
