Now, it’s worth $1 billion."},"content":{"rendered":"

Arcee AI, the startup he founded in 2023, was focusing on post-training\u2014the process by which an existing model is honed for humans. But McQuade saw an opening: Meta<\/a> had just backed off its push into open-weight models, a vital (and tricky) middle ground in AI. Open-weight models allow companies (and people) to securely run state-of-the-art AI without turning their data over to, say, OpenAI or Anthropic.<\/p>\n

But if McQuade wanted to fill the gap, he and Arcee would have to build their own model completely from scratch, a technical and financial mountain to climb.\u00a0<\/p>\n

\u201cWe saw an opportunity, and we had $30 million in the bank,\u201d said McQuade. \u201cI said \u2018let\u2019s do it\u2019 and I bet the company on it. \u2018Let\u2019s spend 65% to 70% of our capital.\u2019\u201d<\/p>\n

The startup over the coming months burned about $20 million training four open\u2011weight models, including a 400\u2011billion\u2011parameter model called Trinity Large, released in early 2026. $20 million, in AI, is a shockingly low number\u2014conventional wisdom states that you need billions to train a new model, a belief challenged dramatically when China-based DeepSeek surfaced in 2025, with reports that the top-notch model was trained for under $6 million.\u00a0<\/p>\n

In AI, open-weight models are definitionally geopolitical, and China, so far, has dominated the game. Arcee\u2014whose models have beat Meta\u2019s Llama 3, and have benchmarked on par with Mistral and Chinese models<\/a>\u2014has been relatively quiet, but is now stepping forward: the startup has raised its Series B at a $1 billion pre-money valuation, Fortune has exclusively learned. The round was led by Vista Equity Partners, Cambium Capital, and Emergence Capital, with participation from Microsoft\u2019s M12, AI10 Ventures, Hitachi<\/a>, IAG, P7, and Wipro. Arcee declined to disclose the amount raised in this round, but a source familiar with the matter told Fortune it was at least $150 million.<\/p>\n

The cash will funnel towards new open-weight models and products, along with growing Arcee\u2019s partnership with the U.S. Department of Energy. (Arcee will also be working extensively with Vista\u2019s portfolio companies.) However, McQuade is very clear: The ultimate goal is to catch China.\u00a0<\/p>\n

\u201cEveryone talks about China versus the U.S.,\u201d said McQuade (who was previously an early employee at Hugging Face, just acquired by Nvidia<\/a> for almost $13 billion). \u201cMy stance is: just do something great. Catch up to them. Do the work\u2026 In order for the U.S. to take the absolute lead in the AI race, you have to be in the lead when it comes to closed and open. The U.S. is far ahead in closed source, but kind of dropped the ball on open source.\u201d<\/p>\n

McQuade says it\u2019s time to pick up the ball: \u201cWe\u2019re not chasing [Poolside\u2019s] Laguna,\u201d he says. \u201cWe\u2019re chasing [Beijing-based Z.ai\u2019s] GLM Flash.\u201d<\/p>\n

To get there, efficiency is non-negotiable, McQuade said. And, for Arcee, efficiency\u2019s also the game plan: \u201cWe can comfortably say we\u2019re the most efficient lab in the world based on what we\u2019ve done.\u201d<\/p>\n

Building in AI is a high-wire act on its own, but the game at the model layer is that much more viscerally competitive, in the U.S. and abroad. McQuade didn\u2019t just pivot, he dove into the deep end, and I asked him: Why cannonball, when you could\u2019ve dipped a toe in?<\/p>\n

\u201cGosh, adrenaline? I don\u2019t know, I like to push the envelope,\u201d he said. \u201cIn AI, things change so fast, so what\u2019s the point of dipping your toe in. If you fail, you fail, and at least you tried. If you\u2019re going to do something, go all in.\u201d\u00a0<\/p>\n

See you tomorrow,<\/p>\n
