Ventrix Labs is a London-based modular carbon capture company building the first decentralised CO₂ supply chain. As the CO₂ supply is declining, our goal is to make merchant CO₂ cheaper, more resilient, and more reliable by replacing long-haul deliveries with on-site recovery and local distribution.&nbsp;We design capture units that integrate with existing building infrastructure to recover waste gases and produce high-purity CO₂ for reuse or permanent storage through mineralisation. Our modular architecture allows rapid deployment at scale, reducing costs by up to 87, mostly tied to transportation. This closes inefficient emission loops while strengthening the systems cities and industries already depend on.We’ve launched a £500k government-funded trial in Wales, secured 7 LOIs with UK breweries, NHS hospitals, and university estates, and are currently raising our pre-seed round with backing from Imperial’s Undaunted and Alexis Ohanian’s 776 Foundation.At Ventrix, every team member takes on meaningful responsibility from day one, designing, testing, and delivering real systems into the field. We are solving today’s carbon challenge with technology built for the world as it is, creating a resilient circular CO₂ supply that advances both climate goals and economic stability.If you want intensity, growth, and impact, this is for you.
