Co-founder at Flowout
I build & grow SaaS products.
A decade building products — most recently SaaS in the Webflow ecosystem, with one exit along the way. Now building Sigrid, an AI agent for conversion optimization.

Most of my time right now goes into Sigrid, the newest product from Flowout — the studio behind Optibase, Vidzflow and SyncMate too.

About
I'm Sergej, co-founder at Flowout — a Slovenian Webflow studio. Everything else here grew out of it.
I've been building products for over a decade — the recent years on SaaS in the Webflow ecosystem, including Linguana, which I co-built and which was acquired in 2025. These days I live and work in Thessaloniki, Greece.
I occasionally advise SaaS teams on conversion and A/B testing strategy. If that's you, email me — a few lines about your situation is plenty.
