Astravidya secures investment from S-Tech Ventures to scale Ukrainian motor production

Investment builds on S-Tech Ventures’ long-term cooperation with Ukrainian defence sector. Astravidya retains 80% ownership; full output capacity allocated to Ukrainian unmanned manufacturers.

Astravidya, a Ukrainian manufacturer of brushless DC (BLDC) motors for unmanned platforms and ground robotics, has secured an investment from Czech industrial defence group S-Tech Ventures.

The transaction builds on S-Tech’s long-term cooperation with Ukraine’s defence-technology ecosystem. S-Tech holds a 20% stake; the remaining 80% is retained by Astravidya’s founding team, ensuring the company’s engineering leadership stays under Ukrainian ownership. The parties did not disclose the value of the transaction.

„Astravidya was built on the principle that Ukrainian engineering can deliver industrial-grade serial production at full scale. We control the entire technological cycle, from the machines that build our motors to the finished product. The partnership with S-Tech Ventures lets us scale this capability for Ukrainian unmanned manufacturers, with European market expansion as a long-term horizon once the legislative framework permits. This is what it looks like when European industrial capital strengthens Ukrainian defence production from within,” says Rufat Raimov, CEO of Astravidya.

Astravidya will use the funding to build a new serial production line with a target capacity of up to 50,000 motors per month, expand manufacturing facilities, strengthen its R&D centre, and grow the engineering team. The line’s full output will supply Ukrainian manufacturers of unmanned platforms and ground robotic systems. The motors will reach European supply chains once Ukrainian legislation permits defence-technology exports.

„Astravidya represents the kind of Ukrainian engineering Europe needs: real production, real intellectual property, full independence from Chinese supply chains. This is exactly the capacity Europe requires for unmanned platforms. Our role is to give that capability the industrial backbone it deserves, anchor it in EU industrial structures, and integrate Ukrainian manufacturing into European supply chains, with Ukrainian partners as equals,” says Anna Růžičková, CEO of S-Tech Ventures.

Astravidya designs and manufactures BLDC motors with a localisation level above 70%. The company operates its own machining and stator-winding processes and remains independent of Chinese component supply chains. Its engineering team designs and upgrades its own production equipment in-house, which gives Astravidya control over quality, throughput, and unit economics, and shields it from external logistical disruption. These characteristics place Astravidya among the few Ukrainian engineering operations ready to supply European customers in unmanned platforms, ground robotics, and adjacent civil-defence applications at industrial scale.

S-Tech owns the serial production line and leases it to Astravidya, anchoring the operational asset in EU jurisdiction while production continues on Ukrainian soil. In the longer term, S-Tech intends to build a second Astravidya-aligned production line within the European Union, expanding the company’s manufacturing footprint into the EU rather than relocating it.

Astravidya is a certified member of Brave1, Ukraine’s state defence-technology cluster operated jointly by the Ministry of Digital Transformation, the Ministry of Defence, and the General Staff of the Armed Forces of Ukraine. Brave1 membership reflects state validation of Ukrainian defence technologies and provides participants with grant funding, expert review, and access to testing infrastructure.

With this investment, Astravidya becomes part of a portfolio designed to build a fully European industrial base for unmanned and ground robotic systems. S-Tech Ventures already holds Cyber Drone Solutions (unmanned platforms), Noontide Systems (defence AI and computer vision), and Componentas (component manufacturing in the EU). Astravidya completes this chain with motor production, a critical component that few European manufacturers currently supply at industrial scale.
