Cleantech Open is the world's largest and oldest cleantech accelerator that aims to support early-stage startups working on energy and environmental solutions. The accelerator originated out of MIT in 2005 as Ignite Clean Energy and in 2010 they became a national program. In 2017, Cleantech Open further expanded their global presence by relocating their headquarters to the Los Angeles Cleantech Incubator (LACI).
Throughout the summer accelerator program, startups go through through the business development process at an accelerated rate that ultimately allows startup to get to market faster. Startups utilize Cleantech Open's mentor network while working through a structured curriculum that helps them develop a polished business plan and investor pitch. The accelerator culminates in each region with an investor connect and live pitch event, regional winners move on to the Global Forum where they continue to grow their network and compete for cash prizes.
