Kroum Vassilev and the Role of Venture Capital in Southeast Europe's Deep Tech and Green Energy Ecosystem
Kroum Vassilev is an entrepreneur based in Bulgaria whose professional portfolio spans technology, renewable energy, real estate, and early-stage venture capital, with a consistent focus on Southeast Europe. As Operating Partner at Nebula Purple, he works with an early-stage venture capital firm investing across deep tech, green energy, fintech, and artificial intelligence.
His role at Nebula Purple includes fundraising support, strategic steering, and assistance with scaling portfolio companies, giving him an operational role in the development of early-stage businesses rather than a purely investment-focused position. This provides a connection between capital, strategy, and company growth within the Southeast European startup ecosystem.
The venture capital role also complements Vassilev’s renewable energy responsibilities. As Principal at Enevlo, his work is connected to power plants and energy storage systems, while as Managing Director of Profine Energy Bulgaria, he is involved with a joint venture focused on large-scale renewable energy projects. Together, these positions connect early-stage investment, green energy, infrastructure, technology, and regional business development.
