Aezeo

What Aezeo does

Aezeo is a privately-held French SARL founded in 2010 by Samuel Le Berre in Plœmeur, near Lorient in Brittany (now headquartered at 7 rue André Ampère, 56260 Larmor-Plage). The company operates a hybrid business combining a renewable energy training centre, an e-commerce shop for self-construction (auto-construction) hardware, and a turnkey installation subsidiary (Aezeo ENERGIES). Its core technology spans solar thermal collectors (1 m² and 2 m² panels with up to 74% optical efficiency and >80% efficiency after 15 years), hydraulic wood-fired boiler stoves (Julius, Odyssey, Tinylus models tested at 81% efficiency to EN 13400), photovoltaic systems with battery storage cabinets (Bloc Énergie, up to 6,000 cycles / 10–20 year lifespan), and pool solar panels. All products are designed, prototyped, and partially assembled in Larmor-Plage, emphasising durability, modularity, and local Breton manufacturing.

Aezeo generates revenue through four streams: (1) training courses delivered at 6 centres across France (Larmor-Plage, Agen, Toulouse, La Tour du Pin, Blancafort, La Rochelle), QUALIOPI-certified since 2021 and eligible for OPCO, France Travail, and VIVEA funding; (2) e-commerce sales of pre-assembled kits, self-build components, and accessories via monblocenergie.fr and shop.aezeo.com; (3) technical studies (photovoltaic sizing, thermal losses, flue sizing) priced €144–€570; and (4) AEZEO Coach remote support billed in 15-minute increments. Turnkey installations are limited to Morbihan and Finistère, executed by RGE-certified technicians (QualiPV, QualiBois, QualiPAC), enabling customer access to French state subsidies (MaPrimeRénov', CEE, reduced VAT).

The customer base spans private individuals seeking energy independence, professionals and artisans (plumbers, electricians, agricultural workers) seeking upskilling, businesses contracting installation projects, and local governments commissioning bespoke training programmes. The company's go-to-market relies on community-led referrals from 400+ training alumni, content marketing through its blog and newsletter, earned media coverage (France Inter, Le Télégramme, Ouest-France, Low-Tech Lab), and event participation. Aezeo holds no external funding, no parent company, and operates with a small team (1–10 employees) as an independent, founder-led entity.
