  • ENGO

    Led · Equity · Jul 2026

    ENGO develops lightweight smart glasses for runners, cyclists, triathletes and other endurance athletes that use an integrated augmented reality Micro-OLED display to project real-time performance data into the wearer’s field of view. Its eyewear combines embedded display technology with up to 20 hours of battery life in a frame weighing less than 40 grams. The company emphasises miniaturisation, energy optimisation and optical innovation to reduce weight and make the technology unobtrusive. ENGO plans to expand its team and commercial footprint, strengthen sports-industry partnerships and pursue further R&D in display, optics and power efficiency. The company also intends to explore applications for its smart eyewear technology beyond endurance sports. It recently secured €5.1 million in funding to support these plans.

    Elixir Aircraft designs and manufactures carbon-fiber light aircraft aimed at flight schools and pilot training. The company has launched a new program named Equinox as part of its product roadmap. Management is pursuing an international growth strategy and began expanding into the United States shortly before this financing. Following the €45 million round, led by SPI with a €20 million contribution, Elixir plans to ramp production with a goal of delivering nearly 60 training aircraft per year by 2027.

  • Aerix Systems

    Led · Equity · Mar 2026

    Aerix Systems, founded in 2020, builds the AXS Micro, a small, highly agile aerial robot with a 40 cm wingspan, 4 kg weight and a top speed of 200 km/h. The machine can fly on its edge or back, execute abrupt direction changes and operate in winds up to 100 km/h. Aerix targets defense counter‑drone use—particularly against FPV drones—and industrial inspection on hard‑to‑reach sites. After a €1.6 million raise in 2024, the company secured an additional €5 million to industrialize production. Its immediate plan is to launch manufacturing at a rate of several hundred units per month. The new funding is intended to support that production ramp.
