PowerPod is building the future of EV charging solutions for commercial fleets in India. We are a fast-growing, technology-driven startup solving one of the biggest challenges in EV adoption: reliable, accessible, and efficient charging infrastructure and service for commercial fleets. Unlike traditional charging networks, PowerPod operates an asset-light, managed EV charging and battery-swapping platform** designed specifically for B2B fleet operators. Our hubs bring together multiple charging and swapping technologies, supported by proprietary software and 24/7 operations, ensuring maximum uptime and efficiency. With 50+ fleet customers, ₹10 Cr+ annualized revenue, and a growing network of charging hubs in Bengaluru, we have demonstrated that EV infrastructure can be both scalable and profitable. Our approach is simple: solve real problems, build sustainable businesses, and prioritize long-term value over short-term shortcuts. We are a lean, execution-focused team that believes in ownership, first-principles thinking, and maintaining exceptionally high standards. We value people who enjoy solving complex real-world problems, take initiative, and want to see the direct impact of their work. Our ambition is to build the backbone of commercial EV charging in India. We are looking for passionate people who want to build something meaningful from the ground up.

Tetra is leading the clean energy transformation by adding transparency and efficiency into a forgotten industry. Home improvement contractors are left in the past, lacking automation and technology to run and scale their small business. This leaves homeowners without the necessary information to make easy, fast decisions and creates a painful buying process. Homeowners are unaware they can reduce carbon emissions and lower their utility bills. We provide the most efficient and affordable options to homeowners, improve their experience, and coordinate the installation of home improvement projects. In doing so, we're “super powering” contractors by automating admin tasks and allowing them to focus on installation excellence and customer happiness. We’re starting by transforming heating and cooling replacements, a $120 billion industry which makes up 12% of total energy usage in the US. Federal and state government agencies allocate billions of dollars in incentives to help homeowners choose high-efficiency systems—now at unprecedented levels thanks to the Inflation Reduction Act of 2022—but the dollars are historically underutilized due to lack of customer awareness. We’re democratizing and unlocking those incentive dollars. We started in Massachusetts, where we’re now 4%+ of the heat pump replacement market, and launched in New York in mid-2024, where we’re already seeing great traction, validating that our model has the potential to scale nationwide. With backing from the likes of Lerer Hippeau, Gutter Capital, Greycroft, and others, we’re now preparing to do exactly that.

On a daily basis, energy and utility companies face infrastructure, technical and operational challenges that range from government mandates to public concern and budget restrictions. At ULC Robotics we help develop and deploy technology which assists our clients in overcoming these issues, allowing them to get more done with less resources. Our team develops advanced robotic tools and cameras capable of entering live pressurized gas mains to perform inspection and repair. We can analyze and redesign standard processes in order to decrease the time and costs associated with planning and performing routine work. The results we produce enable utility companies to reduce disruption to the public by minimizing excavation and simplifying the engineering process. ULC Robotics can even supply a supplemental workforce to tackle technical services; such as meter exchanges and inspections.
