Top Clean Technology Startups in 2027

At ClearWatt, we’re building the platform that helps people buy, sell and own electric vehicles with confidence. One of the biggest barriers to EV adoption is uncertainty. Buyers don’t know the true condition of a battery. Dealers struggle to communicate vehicle performance. Fleets and leasing companies lack the insights needed to make informed decisions. We’re solving these problems using real-world vehicle data, advanced analytics and AI. Our platform transforms complex EV data into simple, trusted insights. Today, our technology helps consumers understand battery health and real-world range, supports dealerships in selling used EVs with greater confidence, and enables fleets, leasing companies and automotive partners to make smarter decisions. We’re already working with some of the UK’s leading automotive, fleet, insurance and energy organisations, and we’re growing quickly as demand for trusted EV data continues to accelerate. Our mission is simple: remove uncertainty from electric vehicle ownership and help accelerate the transition to cleaner transport. We’re a small, ambitious team that moves quickly and takes ownership. As an early member of the company, you’ll have the opportunity to make a meaningful impact on the product, our customers and the future direction of the business. We value curiosity, initiative, pragmatism and a willingness to get stuck in wherever needed. If you’re excited about technology, sustainability and building products that solve real-world problems, we’d love to hear from you.
