Arcee AI Reaches $1B+ Valuation with Series B to Advance Open-Weight AI
Arcee AI, a U.S. artificial intelligence company building frontier open-weight foundation models, announced its Series B funding round led by Vista Equity Partners, Cambium Capital, and Emergence Capital, valuing the company at more than $1 billion. AI10 Ventures, Hitachi, IAG, M12, P7, and Wipro also participated in the round.
Arcee will use the investment to accelerate development of its next generation of frontier open-weight models, expand its work with the U.S. Department of Energy and its national laboratories, and launch a new generation of products that help organizations customize, deploy and operate open models.
The financing follows a period of rapid technical progress for Arcee. Over the past year, the company developed and released the Trinity family of models, culminating in Trinity Large, a 400-billion-parameter sparse mixture-of-experts model with 13 billion active parameters per token. Arcee developed its entire 2025 model lineup, including Trinity Large, for approximately $20 million, demonstrating a capital-efficient approach to training models at frontier scale.
“Organizations should not have to choose between the capabilities of a frontier model and the ability to control the technology at the center of their work,” said Mark McQuade, co-founder and CEO of Arcee AI. “We founded Arcee around the belief that developers, enterprises and public institutions should be able to inspect, adapt, deploy and own their models. This funding gives us the resources to take that vision further: building more capable open models, expanding the products around them and putting American open-weight AI on a path to compete at the highest level.”

Unlike closed-model services, open-weight models give organizations greater control over where and how their AI systems operate. Customers can deploy models within their own environments, adapt them for specialized tasks and data, and maintain greater visibility into the technology underlying sensitive or mission-critical applications.
Demand for this level of ownership is growing among enterprises, developers, research institutions and government agencies. Arcee’s model and product strategy is designed to make open-weight AI a practical foundation for these organizations without requiring them to compromise on capability, security or cost.
