Structure
YOUR INVESTMENT
IS PROTECTED.
The intellectual property behind PowerBee is owned independently by inventor Zbigniew Sadlak — not by any single company. Your capital goes into a focused operational vehicle. The technology that backs it cannot be diluted.
IP Owner
Zbigniew Sadlak
Exclusive owner of all RCPM and AKS patents. 40+ years engineering, 17+ years perfecting this technology. IP protected independently from any operational entity.
Technology Platform
Revora Engine
The RCPM platform — patented engine architecture enabling a new generation of clean, compact power solutions. Licensed to operational companies.
First Licensee · Now Raising
PowerBee P.S.A.
The first operational company licensed to commercialize RCPM. Focused on portable power generators — the clearest, fastest path to market.
Future Licensees
Drones · EVs · Microgrids · Industrial
Each new licensee targets a different vertical — expanding the platform's reach without diluting existing operations.
Your capital enters at the first operational company. The IP that powers it is held independently — protected, undilutable, and growing in value with every new licensee.
Business Model
HOW YOU
MAKE MONEY.
A capital-efficient licensing model. R&D is de-risked through university partnerships. Revenue scales through licensing fees and royalties — without building factories.
01
De-Risked R&D
Technology developed with Wroclaw University of Science and Technology and validated by Cracow and Warsaw technical universities. Not a garage experiment — institutional-grade research.
02
Licensed to Operators
Each operational company gets a license for a specific market vertical. PowerBee is first — targeting portable generators. Future licensees will address drones, EVs, and microgrids.
03
Recurring Revenue
Licensing fees + per-unit royalties from every product sold. Capital-light scaling — no need to build manufacturing. As each new licensee launches, revenue multiplies.
PowerBee's revenue comes from direct generator sales and OEM partnerships. As the first licensee, early investors capture value before the platform expands.
Market Opportunity
WHERE MONEY
MEETS UNMET NEED.
Portable power is a growing market with no real innovation in decades. Existing generators waste 80% of fuel. Batteries can't match liquid fuel's energy density. PowerBee fills the gap.

12-Stroke Cycle
Not 4 strokes — 12. Nitrogen separation eliminates NOx. Oxygen separation provides natural supercharging. Patented and verified.
3 Patents, 3 Breakthroughs
1st: Rotating cylinder — eliminates inertia. 2nd: Coriolis force solution. 3rd: 12-stroke drive with integrated generator. Patents pending.
Miniaturization 1:5245
Combustion chamber: ~0.06 kg. Modular design: 100 kW from 100 units, under 50 kg total. A platform, not just a product.
