Thriive is a nonprofit providing pay-it-forward loans to developing world entrepreneurs to create jobs, expand small businesses, and strengthen vulnerable communities. These loans, called ThriiveCapital, are repaid not in cash but by donating an equivalent value of job training or basic necessities to people in need. Complementing ThriiveCapital is Thriive's Impact Investment Fund (TiiF), which provides next-level conventional financing to promising and socially impactful enterprises. As a program-related investment (PRI) fund, the primary return is social and charitable rather than financial. TiiF makes debt, equity, and convertible investments at manageable, below-market interest rates to finance growing small businesses committed to social and environmental responsibility.
