The productized version of Growfin: I turned a fintech brief I'd automated for myself into an app anyone can use: describe your field in one conversation with an AI assistant and get a tailored briefing delivered to Slack or email.

02 · About
Operator first.
Builder by default.
I'm a business operator who ships. Final-year BBA student at Audencia × Centrale Nantes, now a freelance Growth Engineer. This summer at Finary I was the solo DRI for Growth Data & Automation: an outbound engine over a 1M-user base, an editorial pipeline publishing daily unattended, eight production tools the teams actually use.
On the side I co-founded Tiro, a B2B venture I ran as COO (prospecting, GTM and onboarding-to-delivery) to real revenue. The thread through everything: I use AI and automation to compress months of work into days, for products used by real people.
What I'm building toward: product and growth leadership at an early-stage fintech. The discipline comes from elsewhere: four-plus years in the gym, climbing walls and long hikes.
