In H2 2025, the Bulgarian startup and VC ecosystem experienced a slowdown, with fewer funding rounds and a lower volume of capital deployed into local startups. The standout deal was once again secured by EnduroSat, same as in H1, when the company completed two significant funding rounds, one of them led by Peter Thiel’s fund.
The rest of the activity in Bulgarian startups focused primarily on the fintech, cybersecurity, and longevity sectors.
Below, you can find the biggest 2025 funding rounds in Bulgarian startups, along with key details about them. Check the rest of the Central and Eastern Europe 2025 mappings here.
