About the Company

grifin

Mobile app automating micro-investing via purchases

Grifin is a fintech app that makes investing accessible by automatically turning everyday purchases into stock buys. The core product is a mobile app (iOS and Android) where users link cards; Grifin uses spending data to automatically invest small amounts into the stocks of the brands they shop at, often via fractional shares, and can build a diversified portfolio. It charges a flat monthly subscription for access to automatic investing, fractional shares, diversification, and educational content. What sets Grifin apart is the direct link between daily spending and investing, making the stock market feel more relatable to retail investors—especially millennials and Gen Z—while providing educational resources to help users learn about personal finance. The company’s goal is to simplify investing, removing friction and intimidation so people can invest in brands they use and love as part of their everyday life.
