About Matias Woloski
Matias Woloski co-founded Auth0 and served as its CTO. Auth0 is a cloud identity platform that helps developers handle authentication and authorization. He and CEO Eugenio Pace founded it in 2013 as a remote partnership, with Woloski based in Argentina and Pace in the US. Crunchbase lists him as an alumnus of the University of Buenos Aires and a former Principal Architect at Southworks. Auth0 later became part of Okta.
On X he posted that he had left Okta and Auth0 after about 12 years. His X bio now says he is building Portal Bosque and digging into education and AI. His LinkedIn profile lists Uruguay as his location.
Crunchbase credits Woloski with 22 personal investments, and PitchBook lists 18 investments as an individual angel. The two databases do not match exactly, so treat both counts as approximate. Dated deals in PitchBook run from 2022 to 2025. They include Strike Security and Latitud (both seed, 2022), Outdid (2023) and Autonoma AI (2025). Crunchbase also lists him as an investor in Mendel's Series A.
His most recent public AI-related round is Veria Labs. The company announced a $3.2M seed on February 9, 2026, and thanked Woloski, describing him as a co-founder of Auth0. The announcement also named Y Combinator, Paul Graham, Gokul Rajaram, MA7 Ventures, Seaplane Ventures and Amino Capital among its backers. Crunchbase describes Veria Labs as a San Francisco company that provides AI-powered continuous penetration testing.
PitchBook also lists Autonoma AI (2025), which it classes as business and productivity software. The sources do not give round sizes or his check size for that deal.
The portfolio data points to early-stage software companies, with a mix of developer tools, security, business software, fintech and education. PitchBook categorizes his holdings under software development applications, network management software, business and productivity software, and educational software. Crunchbase places him in Latin America. He has not publicly stated a check size or a formal investment thesis in the sources reviewed. Third-party aggregator pages list pre-seed and seed as his stages, but those figures are not confirmed by him.
