Origin Story

Founded in 2013 by Sundeep Ahuja, Duro Ventures began as an angel investment platform before evolving into a structured venture capital firm. Ahuja, a seasoned investor and operator, leveraged his network and experience to build Duro as a vehicle for supporting founders with bold ideas and strong missions. Over time, the firm expanded its reach, launching thematic funds such as Climate Capital in 2015 to focus on climate and sustainability startups. Duro also incubated and accelerated companies like Twelve (formerly Opus 12) and Rainforest Connection, demonstrating its commitment to hands-on support. The firm’s evolution reflects a broader trend in venture capital: the rise of founder-centric, sector-agnostic platforms that prioritize impact and founder alignment over rigid sector mandates.
