AICE
AICE is a San Francisco defense-tech startup building autonomous swarms of modular underwater drones to monitor and protect naval assets and coastal infrastructure. Backed by Y Combinator (P26), the company was founded by ex-NASA MIT aerospace engineer Gregoire Chomette and European robotics champion Remi Bouteiller, who pivoted from commercial-building energy sensors to subsea defense after talking to submariners about the gaps in current underwater robotics.
Menos AI
Menos AI is a San Jose-based, AI-native fintech building institutional-grade artificial intelligence for hedge funds and asset managers. Founded in 2024 by a team of quant and AI practitioners, its flagship product Sonar is an intelligent research agent that uses proprietary Alpha Signal Extraction technology to surface timely, differentiated investment ideas from the flood of financial data. The company raised a $5.2M oversubscribed seed round in 2025 and positions its platform as an augmentation layer for investment teams - secure, auditable, and designed to integrate with existing workflows rather than replace the humans who use it.
