MyJouleBox

What MyJouleBox does

MyJouleBox is a Paris-headquartered, pan-African solar energy technology company founded in 2016 that builds integrated hardware and software infrastructure for off-grid and mini-grid solar deployments across West and Central Africa. The company's product portfolio spans IoT hardware — PAYGO-enabled smart meters, the Victron-compatible Nanojobox wireless communication device, the Smartclipper non-intrusive clamp meter, single- and three-phase mini-grid meters, and a smart Solar Home System charge controller — paired with the MYJOULEBOX Suite, a cloud-based management platform that bundles mobile payments, a consumer client interface, call-center tools, stock tracking, technician dispatch, and data analytics. The meters retain multi-year internal history of consumption and production, enabling real-time monitoring and remote management of distributed solar assets.

The business serves two primary segments: enterprise customers (energy providers, mini-grid operators, and solar installers managing distributed fleets across Africa) and off-grid households and communities accessed via PAYGO. GTM is enterprise field sales with a quote-request ("Devis") funnel and live demo scheduling. Revenue combines hardware unit sales, recurring software platform subscriptions, and PAYGO transaction fees; pricing is quote-based and not publicly disclosed. The company operates across six African countries — Benin, Burkina Faso, Niger, DRC, Togo, and Senegal — and has raised approximately $10.9M cumulatively from impact-oriented investors including Acumen, EDFI ElectriFI, GAIA Impact Fund, and Triodos Bank, with a lean team of roughly five identified members led by CEO Paul Berthomieu.

Core offering

MyJouleBox designs, manufactures, and sells an integrated hardware-software solution for solar energy providers and off-grid consumers across Africa. The hardware portfolio includes IoT smart meters with PAYGO capability, the Nanojobox wireless communication device (Victron-compatible), the Smartclipper non-intrusive energy clamp, single- and three-phase mini-grid meters, and Solar Home System charge controllers. The MYJOULEBOX Suite software platform provides real-time monitoring, mobile payments, client interface, call center, stock tracking, technician contact, and analytics to manage distributed solar installations.

Product overview

MyJouleBox is a pan-African startup founded in 2016 that provides a comprehensive solar energy solutions portfolio combining hardware products and software platforms. The hardware offerings include Nanojobox (wireless Victron-compatible communication device), Smartclipper (non-intrusive energy measurement clamps), mini-grid meters (single and three-phase), and Solar Home Systems (smart charge controllers for off-grid access). The software ecosystem is anchored by the MYJOULEBOX Suite — a complete monitoring and management platform that includes mobile payment processing, client mobile interface, call center functionality, stock tracking, technician contact tools, and data analytics. The platform integrates smart meters with PAYGO capability, internal historical data storage, and real-time energy consumption and production tracking. All components work together to enable energy providers to manage both pre- and post-installation operations efficiently.
