Lyuben Belov co-founded and sold Net Info in 2008 for what was reportedly Bulgaria's highest-valuation internet sector transaction at the time, then became a venture investor at LAUNCHub Ventures where he was among the first institutional tech investors in Southeast Europe to back crypto companies as early as 2014. He applies a revenue-centric investment filter even at pre-seed stage, focusing on startups that already have paying customers rather than chasing novelty, and advocates publicly that failure should be destigmatized in Southeast Europe as a necessary path to building successful companies.
