Gorilla Capital Fund III’s 31st investment is Rebelvolt, a pioneering company redefining mobile power with its battery-based e-Generator—a clean, silent, and maintenance-free alternative to traditional diesel generators. Manufactured in Finland and designed for professionals in military, construction, events, and logistics, Rebelvolt delivers reliable power without emissions or noise. It’s the essential tool for businesses transitioning to sustainable operations, offering significant cost savings with grid power being up to 10 times cheaper than diesel.
Rebelvolt Co-founder Vesa Heikkinen shares: “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.”
Gorilla Capital Partner Petri Lehmuskoski adds: “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 we’re investing alongside JMS Consulting Oy, UAV OÜ ja Meri Heikkinen.
