Sequel Venture Partners

Sequel Venture Partners is a Boulder, Colorado-based early-stage technology venture capital firm founded in 1996 and headquartered at 4430 Arapahoe Avenue. The firm manages approximately $400 million in committed capital across its fund vintages and is run by a seven-person investment team including Founding Partners Tom Washing and Dan Mitchell, Managing Director Tim Connor, and William E. Mitchell. With nearly three decades of continuous operation, Sequel is one of the longest-tenured venture capital firms in the Rocky Mountain region. Sequel invests at seed through Series B in early-stage technology businesses across healthcare, enterprise IT, SaaS, clean technology, life sciences, manufacturing, digital health, the Internet of Things, and internet-based services. The firm leads rounds and has made 146 total investments with 37 portfolio exits across its history — a disciplined pace of roughly five new investments per year, reflecting a conviction-led model anchored by long partner tenure and deep Colorado ecosystem relationships. Recent activity includes a $1 million seed investment in Cognixion in June 2024 — a brain-computer-interface and biosignal-recognition platform for nonverbal users — led personally by Founding Partner Tom Washing. The most recent exit was Epicor in August 2024 (enterprise ERP and resource planning). Historical portfolio names include Aztek Networks and InfoNow, among many others across multiple fund vintages. Sequel's longevity and continuity of partnership are core to its founder proposition: the same partners who led investments in 1996 remain active and engaged in 2025, providing an unusual depth of pattern recognition across full technology cycles. The firm's Rocky Mountain orientation gives it a distinctive reach into Colorado and broader Intermountain West deal flow that coastal-focused funds routinely miss.
