13 Houston energy tech startups pitch at Rice Alliance's first virtual event

online only

Rice Alliance for Technology and Entrepreneurship's annual Energy Tech Venture Day is usually hosted as a part of the Offshore Technology Conference that takes over NRG Center each May. However, when OTC announced its cancelation, Rice Alliance made sure the show would go on.

"We had many startups and corporations reach out to us and ask us if we could go ahead with the event in a virtual format, so that's how we ended up where we are today," says Brad Burke, managing director of the Rice Alliance at the start of the event.

Throughout the two-hour pitch event, 39 startups pitched their companies in two minutes and 30 seconds or less. The companies were selected based on input from the alliance's energy advisory board. The companies, Burke says, represent innovations across the energy industry.

An additional 24 companies participated in virtual office hours with investors through a speed-networking process.

"We know that the needs of startups to raise capital, to find customers, and to find pilots is even greater today than it was several months ago," Burke says. "And we know that the needs of energy companies to find innovative technologies to reduce costs and increase production are even greater as well."

Usually at this event, the advisory board decides on the 10 most promising energy tech startups, however, this list will not be revealed this year.

Of the startups that pitched that represented 11 different states and six different countries, 13 call Houston their HQ. Here's what local startups pitched.
