Summary
Product leader with ten years in SaaS, across founding teams and product roles inside other companies. Took Taplio from declining revenue to EUR 7M ARR and cut onboarding churn from 93 percent to 40 percent. Scaled lemcal from zero to EUR 50k ARR in six months. Co-founded two companies that raised EUR 12.5M in total, one of which was sold. Hands-on technically: I run discovery, own the roadmap, and write production code. Relocating to the United States (Florida, California or Texas), and equally set up for fully remote work. French citizen: a US role would require visa sponsorship; fully remote from France requires none.
Experience
Founder & Product Engineer, Independent
Mar 2025 – Present
A deliberate stretch building AI products end to end: research, design, code, pricing and go-to-market, alone or with a co-founder.
- 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
Interim CEO & Product Manager, Taplio
Oct 2024 – Mar 2025
The LinkedIn growth product I was brought in to turn around, with revenue already falling.
- Started from usage, not from the roadmap: what people searched for most, and where they actually spent their time
- Rebuilt the features that usage said mattered, and left the rest alone
- Onboarding churn fell from 93% to 40%
- That retention is what moved the revenue: ARR from €5M to €7M in three months, +30% over six. 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
Product Manager, lemlist
Feb 2023 – Oct 2024
Owned lemcal, a Calendly competitor built around ultra-personalisation.
- Scaled lemcal from €0 to €50k ARR in six months, by making the booking page a piece of personal branding rather than a utility
- 1,000+ companies migrated from Calendly
- Directed a technical team of up to four
- Ran the go-to-market and launch campaigns
