GP @Sequoia, early stage AI. Building towards superintelligence. 1st partner to @heytavus @linear @mach_industries @middeskhq @reflection_ai @skildai
Joined March 2013
🔴Excited to share my TED AI talk! How we advance AI into an era of superintelligence, with true *practical* impact in our world. ❓I ask: For all the groundbreaking milestones we’ve reached, all the intelligence benchmarks we’ve shattered, for the $53B invested in generative

BREAKING: @reflection_ai AI raises $2B at an $8B valuation in a round led by Nvidia
Today we're sharing the next phase of Reflection. We're building frontier open intelligence accessible to all. We've assembled an extraordinary AI team, built a frontier LLM training stack, and raised $2 billion. Why Open Intelligence Matters Technological and scientific

It’s great to see more American open source AI models. A meaningful segment of the global market will prefer the cost, customizability, and control that open source offers. We want the U.S. to win this category too.

I've spent years pushing the boundaries of pretraining—first as lead author on PaLM, then as a lead contributor on Gemini pre-training. Now I'm at Reflection, building open-weight agentic models at the frontier from the ground up. Today we're announcing our Series B to

When @SierraPlatform's team debated which product development system to use, cofounder and CEO @btaylor settled it: “I think we should switch to Linear.” That decision became the foundation for how Sierra's agent development and platform teams operate today. Full story →

We built a robot brain that nothing can stop. Shattered limbs? Jammed motors? If the bot can move, the Brain will move it— even if it’s an entirely new robot body. Meet the omni-bodied Skild Brain:

Congrats to Reflection technical staff member @jerber888  on achieving a new SOTA on ARC-AGI. On his blog, Jeremy explains his methodology and perspective about how to build truly general reasoning agents with RL. “With RL, models no longer just learn what sounds correct based
I'm back at the top of ARC-AGI with my new program. I use @grok 4 and multi-agent collaboration with evolutionary test-time compute

25% of Linear workspaces now use agents and 50%+ in enterprise. Mainly it's Cursor, Devin & Codegen coding agents, directly tasked from @linear to fix bugs and improvements. As one customer said now the bottleneck is reviews: (luckily we’re also making code reviews faster).

Now that's a power up 🦾
Jensen @nvidia just gave our bot a Thor-level upgrade. Pretty sure it is worthy of Mjolnir now. 🔨⚡️
