Arcee AI announced its Series B funding round at a valuation above $1B, led by Vista Equity with participation from Cambium Capital, Emergence Capital, Hitachi, M12, Wipro, and others.
The funding will:
- Accelerate next-gen Trinity models across diverse infrastructure
- Expand its DOE partnership with national labs on Genesis-Science-1, a science model trained on their historical data (DOE is a partner, not an investor)
- Build platform tooling for building, evaluating, deploying, and operating open models in production
The investor mix of software, consulting, and global tech firms underscores the ecosystem forming around Arcee's open-weight model strategy.
