Big Bets invests in software-intensive companies at the earliest possible stage, often before there's even a product, and it specifically looks for hard, complex problems to solve because it believes those attract more attention from customers, employees, and investors than easier ones. The fund makes small investments but stays closely involved with founders, has drawn nearly 100 operators and founders as backers (like Fersen Lambranho and Sergio Furio), and has gotten into companies like Justos before they went on to raise major rounds from investors such as SoftBank and Ribbit.
