Andrew Arruda runs Maniac Ventures as a solo investor who reads and answers every pitch himself, with no partners, no LPs, and no warm intro needed, and he built this direct style after spotting deep learning's potential back in 2014 at the University of Toronto, around the same time and place AlexNet emerged. He later left law to found ROSS Intelligence, an early AI legal company that became a launch partner for OpenAI's first GPT API in 2020, and that founder experience—plus building healthcare data infrastructure at Flexpa—now shapes his focus on technical frontiers like BCI, novel silicon, reversible computing, and decentralized AI training rather than typical software trends.
