Investment thesis
0 AD is a seed-stage investor run by two individuals, Xiaoyu and Kirthi, who invest their own money rather than capital from limited partners. They describe a hands-off approach after investing, in part because they are also building their own company, Attimet (YC F24). As of June 2025 they had invested in 23 YC companies and 3 non-YC companies.
