Rebelvolt is redefining mobile power with its battery-based e-Generator – a clean, silent, and maintenance-free alternative to traditional diesel generators. Manufactured in Finland, Rebelvolt’s solution is tailored for professionals in military, construction, events, and logistics who demand reliable off-grid power without emissions or noise, not to forget that grid power can be up to 10 times cheaper to diesel generated power. By combining cutting-edge energy tech with rugged, field-tested design, Rebelvolt delivers unmatched portability and performance for a growing market transitioning to sustainable operations.
Co-founder Vesa Heikkinen at Rebelvolt comments: “From the start, Gorilla understood our product, customer profile, and international ambitions. Their analytical and founder-friendly approach made them a perfect partner as we accelerate Rebelvolt’s growth. Gorilla’s name as a lead investor convinced other investors to join, enabling us to invest in both product development and Go-to-Market”
Petri Lehmukoski, Partner at Gorilla Capital Oy, comments: “Rebelvolt may not look like a typical Gorilla company at first glance—hardware, not software—but they tick all the boxes that matter to us: capital efficiency, a business rooted in real customer demand, and founders with grounded global ambition. Their combination of rugged hardware, proprietary battery tech, and early practical traction gives them a realistic shot at building a strong position in the transition to sustainable off-grid power. We’re excited to support them as they build toward international scale, one step at a time.”
In this funding round Gorilla Capital is investing alongside JMS Consulting Oy, UAV OÜ ja Meri Heikkinen.
