Co-founder at Woice & Flowout
I build & grow SaaS products.
Building SaaS in the Webflow ecosystem since 2021, with one exit along the way. Now building Sigrid, an AI agent for conversion optimization.

Most of my time goes into Sigrid. The rest goes to Woice, the studio behind Flowout, Optibase and Vidzflow.

About
I'm Sergej. I co-founded Woice in 2021, the Slovenian product studio behind everything listed above.
Since then I've co-built products across the Webflow and SaaS space, including Linguana, 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.
