Production AI in weeks, not quarters
About
Plexe is a Y Combinator-backed AI developer tools company that builds open-source agents to design, experiment with, and deploy predictive machine learning models from natural language prompts. The platform uses a self-correcting team of ML engineering agents to research, evaluate, refine, and ship the best-performing model over an API endpoint, enabling enterprises to go from raw data to production ML in weeks rather than quarters. Founded in 2025 by Marcello De Bernardi and Vaibhav Dubey, Plexe has served 30+ production deployments and millions of daily inferences, targeting engineering and data science teams at mid-to-large enterprises.
