Oilstainlab Holds First Closing on Series A Financing

SAN FRANCISCO, CA — JUNE 18, 2026 — Mavka Capital, a Silicon Valley–based investment banking firm specializing in smart mobility, is serving as exclusive financial advisor to performance EV technology company Oilstainlab on its go-to-market strategy and Series A financing. The Company has held a first closing on the round. Proceeds will fund the start of production of the HF-11 hypercar and first customer deliveries in 2027, advance commercialization of the Company’s Thunder-Volt™ EV platform, and support continued engagement with global B2B partners.

Founded in 2018 by twins Nikita and Iliya Bridan, Oilstainlab is poised to begin physical and dynamic testing of its revolutionary launch product, the HF-11 powered by Thunder-Volt. The HF-11 delivers the analog, ultralightweight 2,000-lb driving experience that enthusiasts demand. Thunder-Volt is available in two swappable forms: a race-ready 10,000-rpm, 650-hp gas engine, or the world’s lightest and only fully manual EV powertrain — each priced at $1.85M. The HF-11 has earned more than two billion media impressions across every major automotive and tech innovation publication and has been showcased at the Goodwood Festival of Speed, SEMA, and Monterey Car Week, with more than half of its planned production run already reserved.

“Oilstainlab is exactly the kind of category-defining company we look to back: a world-class team, a truly differentiated product, and a technology platform that can scale far beyond a single model. I led the Series A raise for Rimac a decade ago, and I see a similar inflection point here. The HF-11 delivers what automotive enthusiasts have been asking for in EV hypercars for years, while Thunder-Volt has the potential to power the entire next generation of sports cars — for OEMs from specialty to production scale.”- Vitaly Golomb, Managing Partner, Mavka Capital

The Company has signed multiple B2B agreements to provide its powertrain, platform, and other component technologies to global OEMs. Oilstainlab leverages its knowledge, experience, and world-class team to empower manufacturers around the world.

Mavka Capital is continuing to support Oilstainlab in completing the Series A round and in exploring strategic partnerships around the Thunder-Volt platform. Parties interested in learning more about the company or the transaction may contact Mavka Capital directly.
