FOUNDERS
Immigrant from Russia living in Austria; solo founder of Yadaphone; self‑taught coder (taught himself to code in 2 months) who then worked ~5 years as an engineer; grew a one-person online calling product from launch to five-figure monthly revenue.
PRODUCT–FOUNDER FIT
Denis built Yadaphone to solve his own problem while traveling—he needed a simple, Skype-like way to call family and institutions from abroad, directly in the browser. As a self-taught engineer and solo founder, he shipped a weekend MVP, iterated fast, and kept the setup flow extremely simple.
