SHERIDAN, WYOMING - April 14, 2026 - Sustaera, a direct air capture startup headquartered in Durham, North Carolina, has closed a $10 million Series A financing round to advance development of what it describes as a low-cost carbon removal technology powered by renewable energy. The raise is part of a broader cluster of milestones that includes a $1 million XPRIZE Milestone Award, selection for Third Derivative's inaugural carbon removal cohort, a multi-year carbon removal agreement with Shopify, and inclusion in Stripe Climate's expanded portfolio - a combination that materially reduces perceived technology and commercial risk for the company at an early stage of development.
