Co-Founder & CTO · Apr 2024 — Jul 2025
Localista
Lucien co-founded Localista and served as Co-Founder and CTO from April 2024 to July 2025. Localista was a B2B event marketing platform that aimed to streamline the management of corporate events.
He led a team of 2 engineers and worked closely with their CPO. He architected and built the entire product from the ground up, creating solutions for guest list optimization, marketing campaigns, real-time event tools, and post-event analytics. The tech stack included TypeScript, React Router (Remix), Redis, and integrations with email engines and data platforms.
The event industry proved incredibly tough to crack — it was very difficult to get event professionals to adopt new technology tools, especially in France. After a long meeting with their main investors, Kima Ventures, they decided it was time to pivot: start from scratch with a new product, new market, and a blank sheet.
