KEY.co
KEY.co is an Austin-based luxury travel company that reimagines the vacation rental as a hotel-grade service experience. It curates design-forward homes and pairs them with in-home services - pre-arrival grocery stocking, private chefs, in-home spa and massage, and a dedicated guest-services team - across dozens of destinations in the U.S., Caribbean, Mexico and Canada. Founded in 2014 by Kim Lalande, the company operates as a three-sided marketplace connecting travelers, property managers and local vendors, and has raised roughly $15.8M to date.
Homeroom
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.
