HOUSTON – (March 9, 2023) – After 42 pitches and more than 300 meetings, investors and energy corporations have selected the eight “Most Promising Companies” at the 2023 Rice Alliance Energy Venture Day.

The yearly event hosted by the Rice Alliance for Technology and Entrepreneurship, which took place March 7 at Rice University’s Jones Graduate School of Business, brings together new energy companies with venture capitalists, corporate innovation groups, industry leaders, academics and service providers.

The 53 energy ventures participating in this year’s event come from across the country and have already raised a combined total of $257 million in funding. Prior to the companies pitching their businesses and technologies in front of attendees, they were matched with investors for one-on-one meetings.
