Seed · AI & Machine Learning · London, United Kingdom · Founded 2024 · 1–10 employees

Plexe operates an applied artificial intelligence laboratory and platform that deploys production-ready AI agents and custom predictive machine learning models directly into customer environments. The technology utilizes an autonomous, self-correcting multi-agent system, allowing non-technical product teams and developers to build, optimize, and deploy models using natural language prompts and REST API endpoints. Founded in 2024, the London-based business secured a spot in Y Combinator's Spring 2025 batch. The company raised a 2.1 million dollar seed funding round in August 2025 to scale its self-correcting multi-agent architecture.
