Altira Group LLC is a Denver, Colorado-based U.S. energy-focused venture-capital firm founded in the late 1990s by Managing Partner Dirk McDermott and operating for more than 25 to 28 years, funding advanced technology solutions across the energy value chain (oil and gas, industrial automation, digital and climate technologies, subsurface and production operations, and adjacent industrial sectors). Altira has raised seven institutional funds to date (including Altira Technology Fund VI LP closed March 2014 and Altira Technology Fund VII closed 2024), distinguished by its strategic partnership model that combines institutional limited partners with a group of U.S. super-independent oil-and-gas industry companies (Fund VI industry partners with approximately USD 30 billion in combined annual capital spend, Fund VII with a partnership of seven industry-leading oil-and-gas companies) who serve as validation partners, prospective customers, and product-testing grounds for portfolio companies under the firm's ''OGNext'' approach. The firm describes itself as having approximately 25 employees and USD 34 million in revenue (2025), with approximately 5 partner-level team members. Recent and historical portfolio companies include FlexGen Power Systems, Infrastructure Networks, Seeq Corporation, and other energy-technology growth-stage businesses.
