ENGO raises €5.1 million for lightweight AR sports glasses

ENGO, a Grenoble maker of augmented-reality glasses for runners and cyclists, has raised €5.1 million in a round led by Ventech, Odyssée Venture and Bpifrance Amorçage Industriel. The company plans to use the capital to hire 20 people across marketing, business development and engineering, and to keep shrinking its heads-up display hardware.

ENGO did not disclose its valuation, current headcount or revenue. It said 90% of revenue comes from outside France, with the United States accounting for half of that international total. Blueprint Partners advised the company on the fundraising.

The round is small compared with the capital going into broader consumer smart glasses, but ENGO is making a specific bet: lighter, sport-focused eyewear can hold a place against platforms from Meta and other better-funded companies. ENGO says its glasses weigh under 40 grams, around half the weight of Meta’s Ray-Ban Display, and offer up to 20 hours of battery life.

Sports data, not general-purpose notifications

Founded in 2020 by Fabrice Berger Duquene and Éric Marcellin-Dibon, ENGO builds glasses that put training metrics such as pace, heart rate and power in a runner’s or cyclist’s field of view. The product integrates with devices including Garmin products and Apple Watch, according to the company.

Marcellin-Dibon also founded MicroOLED, the Grenoble microdisplay company, in 2007. ENGO uses MicroOLED’s optical technology, which gives it more control over its display stack than startups that buy display components off the shelf.

The competitive bar has moved. ENGO’s built-in display was once a clearer point of separation, but display glasses are no longer unusual. Meta’s Ray-Ban Display, launched in late 2025, includes a 600 by 600 full-color heads-up display with brightness of up to 5,000 nits. Shenzhen-based Even Realities recently raised $150 million at a $1 billion valuation for camera-free display glasses.

ENGO’s current pitch is weight, endurance-sport workflows and less device distraction. The company says its aim is to keep athletes focused on performance data without making the glasses feel like a general-purpose computing device.

Backers and market context

Ventech, the Paris venture firm leading the round, has invested in more than 320 companies since 1998, including Vestiaire Collective, and has recorded more than 180 exits, including Believe and Withings. Ventech previously backed MicroOLED, ENGO’s sister company.

Odyssée Venture also participated. The French growth-equity firm has backed nearly 200 companies since 1999. Bpifrance Amorçage Industriel, a €50 million fund launched by the French public investment bank in 2023 to support industrial startups, joined the financing as well. Its usual ticket size is €500,000 to €2 million.

Smart glasses remain a crowded consumer hardware category with unclear winners outside Meta. Grand View Research expects the global smart-glasses market to exceed $3 billion in 2026 and grow about 24% annually through 2033. Tech Funding News has previously reported that Meta accounts for about 69% of shipments through Ray-Ban Display and Neural Band products.

For ENGO, the funding extends the runway for a narrower hardware thesis: specialized eyewear for endurance athletes can compete on weight and data integration while larger players prioritize broader consumer features. The company has not said how quickly the new hires will be added or when the next version of its miniaturized display will ship.
