“The Bulgaria Innovation Hub program is a great opportunity for us, especially because I have the chance to be in San Francisco throughout these upcoming weeks (as part of a parallel networking initiative of BIH). This means that we are able to immediately put what we learn into practice in meetings with clients, investors, and partners. Our goal for the program is to ensure we are making the most of the lectures, engaging with the mentors, asking questions that are relevant to our business, and learning from the rest of the cohort companies,” Iva Gumnishka, Founder and CEO of Humans in the Loop told The Recursive.
