A gym owner discovered that people were training on passes nobody checked. The software he helped build now connects the money, the members, and the moments that keep them coming back.
A music school sells lessons. Its owner spends the day negotiating everything around them. Opus1.io built a business in that awkward interval.
Homeroom is a San Francisco software company that runs the back office for school auxiliary programs - after-school enrichment classes, extended care, summer camps, leagues and tutoring. Founded by Stanford classmates Casandra Espinoza Stewart and Christina Walker, it started as a three-sided marketplace connecting parents, schools and class vendors, then grew into an all-in-one platform handling registration, rosters, attendance check-in/out, contractor payments, compliance and financial reporting. It raised $3.5M in seed funding led by Forerunner Ventures in 2019 to chase a roughly $23 billion U.S. after-school market where more than 40% of children are not enrolled in any program.
