Watt & Well

What Watt & Well does

Watt & Well is a French designer and manufacturer of power electronics equipment for demanding industrial applications, headquartered in Pertuis (Vaucluse) with R&D in Massy and Saint-Estève-Janson, plus sales offices in Houston, Texas and Oslo, Norway. The company was founded in 2008 as Watt Consulting, transitioned to industrial equipment production from 2013 onward, and rebranded as Watt & Well in 2015. It operates three vertically organized business units: E-Mobility (power modules up to 100 kW for AC/DC and DC/DC EV fast charging, the BMPU-R2 bidirectional V2G module, and the SECC/EVCC communication controllers certified to CCS, CHAdeMO, MCS, and OCPP), Energy (Nar Motion downhole motor controllers and step-down DC/DC power supplies rated to 175–220°C for oil & gas, geothermal, and renewables including SBM Offshore's WEC S3), and Defense & Space (fault-tolerant motor controllers, including the CMTP delivered to ArianeGroup for the Ariane 6 second stage, and power electronics developed under EN9100/ECSS processes). The portfolio rests on certifications (UL 2202, UL 2231, CSA C22.2 No. 346:22, EN/AS/JISQ 9100, ISO 9001) that are themselves barriers to entry in space- and EV-grade power conversion, with GaN switching used in the ARCHIMEDES bidirectional charger program.

The company's revenue mix is hardware-led (over 80% of revenue from equipment sales per company disclosure), complemented by engineering consulting and after-sales training/support services. Watt & Well goes to market through direct enterprise sales supported by field application engineers, with regional sales hubs in France, the Nordics, and North America; for India it has signed a manufacturing partnership with Servotech. Production currently sits at ~3,000 units per year at Pertuis, with a stated tenfold ramp to ~30,000 units/year targeted by 2026 alongside the build-out of US manufacturing. The customer base spans OEMs and majors including Renault, NIDEC, e-Totem, Welltec, ArianeGroup, Latitude, SBM Offshore, Kverneland Energi, WattAnyWhere, and research institutions (University of Delaware, Technical University of Denmark). Disclosed FY2024 revenue is €18.4M, the company has 110+ employees, invests 30%+ of revenue in R&D, and is venture-backed via a €10M Series A closed in October 2022 with TiLT Capital (Siparex), BNP Paribas Développement, and Bpifrance.
