“It's not even a problem that we can't understand and see with our eyes,” said Pearl during the 2022 MIT Sustainability Conference. “However, we do have the solutions for it.” is using artificial intelligence to determine what tailored dietary supplement plan a cow herd needs for good gut health. It was one of eight startups featured during the conference looking for investment in their clean innovations.
