Mobius Venture Capital

Mobius Venture Capital is a legacy early-stage venture capital firm co-founded by Brad Feld in 1996 and headquartered in Boulder, Colorado, with an additional office in Palo Alto, California. For its first decade of active investing, Mobius positioned itself as a multi-sector firm led by seasoned operators and former entrepreneurs, backing companies in enterprise applications, enterprise infrastructure, fintech, hardware, alternative energy, healthcare, and productivity software. Its last active investing fund, Mobius Technology Ventures VI, closed at approximately $330 million and invested in more than sixty technology companies. The firm leads rounds and deployed capital primarily between 1996 and 2006. Brad Feld departed to co-found Foundry Group in 2007 alongside Seth Levine, Jason Mendelson, and Ryan McIntyre, all of whom had been associated with Mobius, effectively making Foundry Group the successor platform. Across its history Mobius made roughly 299 disclosed investments and achieved 99 portfolio exits, including four IPOs and 23 acquisitions. Notable exits include Impinj (NASDAQ IPO, RFID semiconductors), Bloom Energy (NYSE IPO in June 2018 at a $1.59 billion market cap), Rally Software, Return Path, HomeAdvisor, Infinera Corporation, VeriSign, Geocities, and ELoan. The breadth of the portfolio — spanning energy, internet infrastructure, communications, and enterprise software — reflected a generation of generalist venture investing before sector specialization became the norm. Mobius Venture Capital is registered with the SEC as an investment adviser but is no longer deploying new capital. The firm continues to manage its legacy portfolio and wind down in an orderly fashion, with its historical track record serving as the foundation for the careers of several prominent investors who went on to shape the Boulder and Denver startup ecosystems.
