Co-founder at Woice
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.

About
I'm Sergej. I co-founded Woice in 2021, the Slovenian product studio behind everything listed above.
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.
