About Remora

We’re building modular carbon capture systems, turning exhaust into beverage-grade CO₂ sold to breweries and greenhouses. We deploy in regions facing severe CO₂ shortages, where prices are highest, allowing us to generate high margins without relying on tax credits or carbon credits. We’ve raised over $115 million in funding from top investors including Lowercarbon Capital, Union Square Ventures, First Round Capital, Y Combinator, and Valor Equity Partners.
