Source→“Trajectory raised a $40M Series A, Sequoia-led with Bessemer and Radical Ventures. Angels include Jeff Dean and Fei-Fei Li.”
Source→“It must be extraordinarily validating, if you're Jeff Dean, to leave as a non-CEO of a two or three trillion dollar market cap public company and have the stock go down by a couple of hundred billion dollars.”
Source→“Google's efforts so far are B plus, A minus. They're not A plus... you could look at it and say whatever Google was doing wasn't quite working... They've kind of got a model out there, but they haven't made any impact whatsoever in coding.”
Source→“I think Vinod's leading the round, right? Or co-leading the round or something. So he's just redoing. He already, granted, OpenAI hasn't gone public, but he's already had a little bit of a win here, right? That guy, Vinod, right? So he's just doing the playbook again.”

Source→“Jeff Dean: Renowned computer scientist; former Google Senior Fellow and Google AI lead. Angel investor in P-1 AI's $50M Series A — his participation signals credibility for AI applied to physical engineering systems.”
“P-1 AI is building engineering intelligence for designing complex physical systems—an attempt to push AI beyond code generation into real-world engineering work. A $50M Series A led by NEA, with Radical Ventures and a stacked angel bench including Jeff Dean and Peter Welinder.”
“Jeff Dean argues that the mainstream assumption that agents break down after 10-30 steps is outdated. The real frontier is multi-day or multi-week autonomous runs on genuinely complex tasks.”
Source→“Chief Scientist, Google DeepMind. Creator of MapReduce, Bigtable, TensorFlow, TPUs, and a key figure in Gemini development.”
Source→“Google's frontier model family. Cited specifically as a beneficiary of distillation techniques — the Flash model is distilled from the larger Pro model, producing best-in-class benchmark performance at its size/speed tier.”
Source→“Would you rather hire that person and not hire people who are medium engineers but not Jeff Dean level with the same amount of budget you have?”
Source→“Every core file in Google's infrastructure — from Google File System to MapReduce to Bigtable — had Jeff Dean or Sanjay Ghemawat as the first author.”
