Use Grifin to build healthy investing habits by rounding up everyday purchases into stock investments. Every time you shop at a publicly traded company, the app invests a small amount (like $1), helping you own shares of brands you already use. It connects to your cards via Plaid, lets you customize spend thresholds, adjust investments, and pause rounds. Ideal for beginners who want a hands-off, fun way to invest without needing big sums.
