CleanTech Open

CleanTech Open CleanTech Open was a U.S.-based accelerator and competition designed to discover, promote, and accelerate entrepreneurial innovations in renewable energy, sustainability, and environmental technology. Founded in 2005, the program connected early-stage teams with industry mentors, investors, and corporate partners through regional and national contests modeled after business plan competitions such as MIT $100K Entrepreneurship Competition and events hosted by Y Combinator. The initiative operated across multiple United States regions and maintained partnerships with universities and research institutions including Stanford University, University of California, Berkeley, and Massachusetts Institute of Technology.

History

CleanTech Open emerged in 2005 amid growing interest in cleantech after policy milestones such as the passage of the Energy Policy Act of 2005 and renewable deployment events exemplified by markets influenced by the California Solar Initiative. The organization grew from a regional showcase in California into a national competition with regional affiliates in cities like Boston, San Francisco, Chicago, and Austin. Over time, CleanTech Open engaged with philanthropic organizations such as the Kauffman Foundation and corporate partners including GE, Siemens, and Intel to expand programming. The competition evolved alongside investor trends marked by firms like Kleiner Perkins, Sequoia Capital, and Khosla Ventures increasing cleantech allocations in the late 2000s and early 2010s. Major program changes mirrored shifts in policy and market signals tied to the American Recovery and Reinvestment Act of 2009 and international events such as the United Nations Climate Change Conference sessions.

Organization and Structure

The CleanTech Open operated as a non-profit entity with a governing board and an executive team modeled after accelerators such as Techstars and Plug and Play Tech Center. Its governance included advisory panels composed of executives from Deloitte, PwC, and Ernst & Young as well as academics from Harvard University and Columbia University. The program used a regional-to-national framework: entrants competed in regional competitions coordinated with local partners like Los Angeles Cleantech Incubator and incubators affiliated with New York University and University of Texas at Austin. Mentorship networks drew on professionals from Schneider Electric, ABB, BP, and venture groups such as NEA and General Catalyst. Financial oversight and sponsorship were provided by corporate supporters including Bank of America and foundations such as the Rockefeller Foundation.

Competitions and Programs

The core offering was an annual competition structured into regional rounds, semifinals, and a national finals showcase resembling pitch formats used in Slush and South by Southwest. Tracks addressed sectors like solar power innovations, energy storage systems, water treatment technologies, advanced materials, and transportation solutions. Program components included mentorship circles, business model workshops delivered with partners like Ernst & Young and McKinsey & Company, and investor pitch events attended by firms such as Andreessen Horowitz and Bessemer Venture Partners. Specialized streams were sometimes launched in partnership with agencies like the Department of Energy and think tanks such as the Rocky Mountain Institute. Prize support combined cash awards, in-kind services (legal counsel from firms like Wilson Sonsini), and introductions to corporate procurement teams from companies including Shell and BP.

Notable Alumni and Winners

Across its history, the program showcased startups that later appeared in investment rounds and acquisitions involving firms like Tesla, Inc. and ABB. Notable alumni included companies that scaled into commercial markets for photovoltaics and battery storage and firms focused on agritech and waste-to-energy conversions. Alumni outcomes cited in business press included venture funding rounds led by investors such as Lux Capital and Foundation Capital, and strategic partnerships with utilities including Pacific Gas and Electric Company and Southern Company. Several winners engaged in technology licensing with laboratories like National Renewable Energy Laboratory and Lawrence Berkeley National Laboratory. Individual founders from alumni teams later took roles at accelerators such as Elemental Excelerator and served as speakers at conferences like Ceres Conference.

Impact and Outcomes

CleanTech Open aimed to accelerate commercialization pathways by reducing market entry friction for early-stage technologies and improving investor preparedness similar to outcomes claimed by accelerators like Y Combinator. Measured impacts included alumni capital raised in seed and series rounds, corporate pilot projects, and acquisition events that linked startups to larger industrial partners such as Siemens and Schneider Electric. The program influenced regional innovation ecosystems by coordinating with municipal initiatives in San Francisco, Denver, and Austin and by feeding talent pipelines to university-affiliated incubators like Berkeley SkyDeck. Critiques in trade publications noted sector-wide headwinds faced by cleantech startups during periods dominated by policy uncertainty exemplified by debates in the United States Congress and variable investment cycles led by firms like BP Ventures. Nevertheless, CleanTech Open contributed to the visibility of early-stage cleantech ventures and to networks connecting entrepreneurs with investors, corporate partners, and national laboratories.
