Overview
Basis Theory, based in Mill Valley, United States, has raised $33M in a Series B round on October 14, 2025, with participation from Costanoa. The company built to keep customers transacting. The round will be used to accelerate product development, expand the team, and scale go-to-market operations.
Operating in the financial services sector, Basis Theory is positioned to capitalize on growing demand for innovative solutions in this space. The company was founded in 2020 by Colin Luce. Colin brings deep domain expertise and a track record of execution that attracted investor confidence in this round. With fresh capital, the company is expected to invest heavily in R&D and talent acquisition, signaling a period of aggressive growth ahead.
Market Outlook
This funding positions Basis Theory as one to watch in the financial services landscape. As the company scales, it will likely become an increasingly attractive partner — and customer — for B2B vendors looking to sell into well-funded, growth-stage companies. The post-raise window of 60-90 days is typically when startups are most receptive to new tools, services, and partnerships.
