Montpellier's Wheere raises €8.5M bridge round to prove indoor geolocation that works through concrete

Montpellier-based Wheere has raised €8.5 million to fund the next stage of its indoor-geolocation technology. The financing is explicitly a bridge round ahead of a future Series A, and a follow-on to the company's €11 million seed in 2023. No new lead investor came in: the round was led by existing shareholders, including Blast Club (€2.4 million), entrepreneur Éric Larchevêque (€1 million), Sofilaro (€0.5 million) and existing business angels.

Geolocation where GPS goes dark

The problem Wheere works on is a familiar gap: GPS does not work indoors. Satellite signals are too weak to pass through walls, floors and the deep concrete of industrial sites, tunnels and underground levels — which is exactly where many companies most need to know where their people and equipment are. Founded in 2020 by Pierre-Arnaud Coquelin and Antoine Carrabin, Wheere has built a patented low-frequency (VHF) positioning system that, it says, penetrates up to 50 metres of concrete.

Its early adopters are industrial heavyweights — TotalEnergies, EDF and L'Oréal among them — the kind of energy, manufacturing and logistics operators that run large, complex sites where indoor positioning is an operational and safety problem rather than a convenience. The longer-term ambition reaches further: a low-Earth-orbit PNT (positioning, navigation and timing) constellation, an attempt to extend the technology from inside a single building to a wider sovereign positioning layer.

The structure is the story

What makes this round notable is less the headline figure than its shape. Of the €8.5 million, only €4.2 million is dilutive equity; the other €4.3 million is non-dilutive — bank loans and public grants. That mix lets Wheere fund its roadmap while limiting the equity it gives up before a priced round.

And the roadmap is specific. The capital is meant to carry the company through an 18-month plan: launching an orbital proof-of-concept in the first half of 2027 and signing multi-year commercial contracts — the two milestones that would de-risk the technology enough to unlock a larger Series A on better terms.

CEO Pierre-Arnaud Coquelin frames it as a staging point: "Wheere is on track to redefine geolocation standards, and we are ready for this next stage of growth." The bet is disciplined — prove the hardest claims cheaply first, then raise the big round against results rather than promises. Whether the orbital proof-of-concept lands on schedule is the hinge the whole plan turns on.
