Carnrite Ventures

Carnrite Ventures is the venture capital arm of the Carnrite Group, founded in 2015 and headquartered in Houston, Texas. With approximately $25 million in assets under management, the firm partners with entrepreneurs building transformative companies in energy, climate technology, and healthcare technology. The firm was built by operators: Founder and Managing Partner Alan Carnrite leads alongside Jeffrey Carnrite, who joined in 2020 and oversees deal sourcing, due diligence, and portfolio management. Carnrite leads rounds from Pre-seed through Series B, deploying checks of $100,000 to $2 million across 65 investments in energy, cleantech, healthtech, and biotech. The portfolio has produced 17 exits over the firm's decade of investing. Notable portfolio companies include Haven in energy storage, Wheeler Bio in biotechnology, and Nest Collaborative, a healthcare and lactation services platform that raised a Series A in January 2024. The most recent investment was in RBL LLC, a biotech venture creation studio, in September 2025. Beyond capital, Carnrite provides executive leadership, turnaround services, and back-office operational support to portfolio companies — reflecting roots as an operator-first organization rather than a conventional financial investor. Situated at the heart of Houston's energy ecosystem, the firm maintains strong ties to the traditional and emerging energy sector, giving portfolio companies direct access to an industry network that spans major operators, corporates, and technical experts across the Texas energy corridor.
