At Maiven we’re driven by a mission to rapidly decarbonize residential buildings, democratize access to clean energy and incentives, and support an equitable energy transition. Our aim is to make the sustainable choice not only the right choice but also the most financially savvy one.We believe people want to do the right thing—for the planet and their wallets—but the right thing isn’t always obvious. Especially when it comes to energy upgrades and rebates, the landscape is often confusing and inaccessible. If we want people to make climate-friendly choices, we have to make the right thing also the easy and financially beneficial thing. That’s what we’re all about at Maiven.Maiven is a fast-moving, mission-driven startup building software to help energy programs reach their decarbonization, grid flexibility, and equity goals faster and at lower cost. We do that by empowering homeowners and renters to identify the best energy upgrades for their situation—and then making it easy to act on them.We’re a small team doing big things—and we’re just getting started.
