How it started
Denis Yurchak, a trained diplomat who taught himself to code in two months, built many unsuccessful side projects while freelancing. A frequent traveler and loyal Skype user, he saw Pieter Levels tweet about Skype shutting down in March 2025 and built an MVP in a weekend. A Reddit launch brought sales within minutes; he reached 10K registered users, 4,500 paying customers and 20 enterprise clients in seven months.
