Managing Director, Profine Energy Bulgaria · Principal, Enevlo · Operating Partner, Nebula Purple
Overview
Kroum Vassilev's professional background spans technology, renewable energy, and real estate. He currently holds three concurrent operating roles: Managing Director of Profine Energy Bulgaria, Principal at Enevlo, and Operating Partner at Nebula Purple, each based in or focused on Bulgaria and the broader Southeast European region.
These roles place him at the intersection of two related but distinct areas of activity: the development of clean energy infrastructure, and the funding of early-stage companies working in deep tech, green energy, fintech, and artificial intelligence.
Profine Energy Bulgaria
As Managing Director of Profine Energy Bulgaria, Vassilev leads a joint venture between Profine and Wirth Gruppe focused on large-scale renewable energy projects in Bulgaria. The venture addresses the country's growing demand for clean energy infrastructure as part of the broader European clean energy transition.
A closer look at the venture's structure and objectives is available in the article on Profine Energy Bulgaria's renewable capacity building.
Enevlo
Through his principal role at Enevlo, Vassilev is involved across the full project lifecycle of power infrastructure: planning, financing, construction, and operation of power plants and energy storage systems. Enevlo's scope reflects the technical complexity of modern grid infrastructure in emerging European markets, where storage and generation increasingly have to be planned together.
Nebula Purple
As Operating Partner at Nebula Purple, Vassilev supports early-stage companies in the SEE region across deep tech, green energy, fintech, and artificial intelligence. His role spans fundraising support, strategic input, and operational scaling for portfolio companies.
Nebula Purple's regional focus positions it within a venture ecosystem that is still developing relative to Western Europe. More on the firm's approach is covered in the article on Nebula Purple's venture capital focus in the SEE region.
Professional Orientation
Holding concurrent leadership positions across energy infrastructure and venture capital requires operating across industries with different capital structures, regulatory environments, and growth timelines. This cross-sector exposure informs Vassilev's approach to both long-cycle infrastructure projects and faster-moving early-stage investment decisions.
