Chanty’s own blog credits founder Dmytro Okunyev, in his own words: he built the first version internally at his software company, Digifico, in 2012, then spun it out as a bootstrapped, self-funded product in 2017 rather than take on investors — a "fun side project" that had grown to more than 70,000 teams by 2021, per the same post.
