What TESUP does

TESUP (operating under the legal entity Wekraft) is a UK-based industrial manufacturer that designs, assembles, and sells residential-scale wind turbines and flexible solar panels directly to homeowners worldwide. Its core product line comprises the Atlas vertical-axis wind turbine (15 kW motor, 4.5 kW peak) and the Magnum horizontal-axis wind turbine (15 kW motor, 12 kW peak), both precision-engineered from 100% recyclable aluminium and designed for 15-minute self-assembly without professional installation. The Flex Solar Panel (460 W) complements the wind turbines to enable combined wind-and-solar home energy systems, and the My TESUP mobile app provides IoT-based remote monitoring and control of installed equipment.

The business operates a direct-to-consumer e-commerce model through its own storefront (tesup.com and regional sites such as tesup.com/uk), shipping to customers in over 50 countries. Assembly is performed in London and product design is based in California, giving the company a transatlantic manufacturing and engineering footprint. Hardware is sold as one-time purchases at £499–£799 per unit, with promotional discounts and free shipping used as consumer-acquisition levers. The My TESUP app hints at a potential recurring service layer, but pricing models for that component are not publicly disclosed.

The customer base is entirely residential and consumer in nature, with named UK homeowners (in Wales, Scotland, and Sutherland) cited as testimonials. There are no disclosed enterprise customers, no institutional investors, no public funding rounds, no patents, and no AI/ML capabilities referenced in available material. Revenue, headcount trajectory, and growth metrics are not publicly disclosed, which limits financial visibility.
