AquaCycl, a San Diego-based wastewater treatment startup, took home the grand prize at the San Diego Angel Conference on March 15. A panel of angel investors that had vetted the finalists for months selected AquaCycl as the winner, for a $200,000 cash prize. The company was also voted in as the audience favorite. AquaCycl was co-founded in 2016 by CEO Orianna Bretschger, Vice President of R&D Sofia Babanova and Vice President of Hardware and Manufacturing Ryoji Naito. The company developed a technology that uses electricity-generating bacteria to speed up wastewater treatment rates, resulting in a more efficient, lower-cost option.
