Treehouse’s wager is that the hardest part of electrification is not the charger, battery or heat pump. It is the unruly journey from “I want one” to a permitted wire in the wall - and the company is trying to turn that journey into a product.
The British fleet-charging specialist learned that the valuable bit is not the socket. It is knowing which van must leave at dawn, how much power the depot can spare and who answers when a charger sulks at 2 a.m. Its trip from a Suffolk pig shed to Pod and EDF is a sharp lesson in building - and financing - hard climate infrastructure.
Anyone can sell a charger. COIL built a business around the permits, panels, trenching, software and phone calls required to make one useful - then sold that missing layer to Wallbox.
Electric trucks are arriving faster than megawatts. Terawatt’s answer is a network of powered depots that turns years of permits, trenching and utility negotiations into one line on a fleet operator’s monthly bill.
Enteligent is a Morgan Hill, California startup building DC-to-DC power electronics that skip the wasteful AC conversion steps between solar panels, batteries, and the things that consume electricity. Its flagship products are the world's first solar-powered DC-to-DC bidirectional EV charger and the NMax module-level power optimizer for rooftop solar, and it is extending the same direct-current approach to AI data center racks. The pitch is simple arithmetic: keep electricity in DC form from generation to load and you lose less of it, which means faster charging, cheaper installs, and higher solar yields.
Merge Electric Fleet Solutions is a Houston-based company that gives commercial fleets a clear, affordable, data-driven path to going electric. Launched in 2021 by EV industry veteran Glen Stancil and backed by Pickering Energy Partners, Merge handles the full journey - analyzing which vehicles to electrify, designing and deploying charging infrastructure, and operating it - through products like EV360 fleet analysis, PowerRail modular charging, and the all-inclusive FleetScription EV subscription. The pitch is simple: electrification simplified.
Flipturn is a New York-based software company building the unified control center for EV fleet and charger operations. Its hardware-agnostic, cloud platform connects to any OCPP-compliant charger, giving fleet operators and property managers real-time visibility into charger health, automated load balancing and demand-charge mitigation, driver billing with no app required, and AI-powered diagnostics. Founded in 2022 by Samsara and Stripe alumni Katie Siegel and Sashko Stubailo, Flipturn serves Fortune 500 fleets, municipalities, and multifamily operators, and raised an $11M Series A led by CRV in November 2024.
GILLIG is a 135-year-old American bus maker based in Livermore, California, and the second-largest transit bus manufacturer in North America. Every GILLIG bus - clean diesel, CNG, hybrid, battery electric, and a coming hydrogen fuel cell model - is designed and assembled by U.S. workers for public transit agencies across the country.
