Executive Summary

Leeroo is a London-based, YC Spring 2025 company building "trainable" AI agents that continuously learn from organizational knowledge bases, human feedback, and past agent experiences — starting with data and AI teams in banking, finance, and healthcare. The market timing is genuinely excellent (agentic AI growing at 46%+ CAGR) and the founding team's technical pedigree is elite (dual EPFL PhDs, Meta AI, LinkedIn AI, Naverlabs). However, at pre-seed with only $500K raised, zero confirmed paying customers, and a target market defined by 12–24 month enterprise sales cycles, the company's traction is purely narrative at this stage. The single biggest risk is a compounding one: platform commoditization from trillion-dollar incumbents (Microsoft, Salesforce, OpenAI) converging on identical positioning, colliding with razor-thin runway and no commercial leadership on the founding team.
