# Tristan Berguer

> Ex-founder turned product engineer · Interim CEO at Taplio · ex-lemlist · one exit. Based in Perpignan, France. Product Lead, Principal PM, Founding PM or Product Engineer. Full-time or freelance.

I own the roadmap, the number, and the pull request.

Ten years of SaaS, from founding teams to product roles inside other people's companies. Activation, retention, churn and pricing on one side; TypeScript and shipped product on the other. Two companies I co-founded raised €12.5M between them, and one was sold.

## Work authorisation

## Roles
- 2025-03 – present: Founder & Product Engineer at Independent. A deliberate stretch building AI products end to end: research, design, code, pricing and go-to-market, alone or with a co-founder. Results: Senthor, an AI-crawler paywall: co-founder and CEO, live; Atyla, measuring brand visibility inside AI answers: co-founder, live; BeeSecure, an AI security co-pilot: built solo in 11 days; Four products shipped in 18 months, each one coded and priced by me.
- 2024-10 – 2025-03: Interim CEO & Product Manager at Taplio. The LinkedIn growth product I was brought in to turn around, with revenue already falling.

Growth came from keeping customers, not from buying more; Ran the product-led growth motion and led a cross-functional team of developers and marketers.
- 2023-02 – 2024-10: Product Manager at lemlist. Owned lemcal, a Calendly competitor built around ultra-personalisation.
