Summary
🤩
Rockstar🎓
Top SchoolAlex Lebrun is a serial entrepreneur and AI-focused software leader based in Paris, currently cofounder & CEO of Nabla. He co-founded Wit.ai (YC W14) — one of the earliest .ai startups — which was acquired by Facebook, then worked at FAIR, and earlier built VirtuOz from a bootstrapped codebase to an acquisition by Nuance. He blends C‑level strategy with hands‑on NLP engineering, contributing to core parsing logic in projects like Facebook’s Duckling (time and quantity parsing and multilingual corpora). Educated at École Polytechnique and Télécom Paris, he has a proven track record of raising capital, scaling teams across Europe and Silicon Valley, and shipping conversational AI and intelligent virtual agent products. Less obvious: he still dives into parsing rules and data adjustments himself, not just high-level product strategy.
