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 accelerate this mission. What excites me most is the team of world-class researchers who are deeply bought into this mission and the opportunity to build a frontier lab from scratch. Pre-training at scale. RL at scale.

If you're passionate about this mission and pre-training/RL at scale to advance the open frontier, join us on our ambitious journey! DM me. We’re hiring in SF, New York and London:
