ENGO spun out from MICROOLED in September 2025 and has since focused exclusively on a single product mission: building AR glasses for endurance athletes that are light enough to wear for hours and display only the data that matters during a race or training session .
ENGO's flagship product, the engo3, is a pair of sports sunglasses with a Micro-OLED augmented reality display embedded directly in the lens . The system projects performance data—heart rate, pace, power output, and more—roughly three meters ahead of the wearer, color-coded by training zone .
| Specification | Detail |
|---|---|
| Weight | 38.5 grams (prior engo2: 36g ; future target: ~30g ) |
| Battery life | More than 20 hours on a single charge |
| Display | Micro-OLED, multi-color heads-up display |
| Compatibility | Garmin watches, Apple Watch, Suunto, and other Bluetooth-enabled devices |
| Data shown | Heart rate, pace, cadence, distance, power, and 40+ additional metrics |
| Lens type | Polycarbonate, impact-resistant, category 3 (high sun protection) |
The engo3 has no camera, no audio, and no smartphone notifications — it is a purpose-built performance tool that shows only real-time training metrics .
ENGO designs its eyewear specifically for runners, cyclists, triathletes, and other endurance athletes who need to monitor performance data without breaking their visual focus on the road, trail, or track . The entire user interface is designed to be read at a glance while maintaining full situational awareness.
ENGO outlined three primary areas for the €5.1 million in new capital :
ENGO's central engineering challenge is straightforward: the lighter the glasses, the longer athletes wear them. The company has already achieved a 36–38.5 gram frame — comparable to standard premium sports sunglasses . The engo2 weighed 36g (standard) or 41g (large), and the engo3 added a color display and doubled battery life while gaining only 2.5g .
The long-term target of roughly 30 grams would mean the AR glasses weigh less than many non-smart sports glasses on the market .
Ventech, the lead investor, has backed more than 320 companies since 1998 (including Vestiaire Collective, Believe, and Withings) and previously invested in ENGO's sister company, MICROOLED . Odyssée Venture and Bpifrance Amorçage Industriel co-led the round, with Bpifrance's participation underscoring the industrial and national-technology dimension of the project .
Most AR glasses aimed at consumers (such as Meta's Ray-Ban Stories or Xreal's headsets) include cameras, speakers, and general-purpose apps, pushing weight above 50–80 grams. ENGO strips all non-essential features away: no camera, no audio, no app store — just a lightweight Micro-OLED display, gesture sensors, and Bluetooth connectivity to sports watches . This singular focus on endurance athletes allows ENGO to keep the weight below 40 grams while delivering the specific data runners and cyclists rely on.
The trade-off is clear: the engo3 does not record video, take calls, or play music, but it also does not distract from the task at hand .
