For families living in large cities, finding great activities for children can be problematic. Some places are better than others, but do you really want to make a long-term commitment when there are many others to see? Plus, you may want  your children to enjoy a diverse mix of classes. To help parents navigate the options, Kidpass is a service focused around activity providers for kids that mirrors what ClassPass does for fitness.

The subscription service for kids’ classes had previously raised $1.2 million to fulfil its mission, but it’s now adding to that total, thanks to investments from Y Combinator and Gymboree founder Joan Barnes.

Targeting a $30 billion-plus industry, KidPass gives parents a choice of more than 50,000 activities their children can participate in — from music classes for babies to kids’ yoga, swimming lessons, soccer, arts and crafts, cooking classes, puppet shows, museum programs, even building a robot, making chocolate pizza, or Star Wars-themed light saber fencing. KidsPass said it has activities for kids ages 2 months to over 12 years.

Company cofounder Solomon Liou explained that KidPass was created when he and his partners became parents and felt like “the process of finding great activities for our little ones was both frustrating and time-consuming. In fact, we often spent more time searching for and scheduling activities than we did at the class itself!” It can be difficult to find things to entertain children — especially with busy schedules — so KidPass wants to do the footwork for you.

Since its debut 15 months ago, Liou said the company has been growing between 20 and 30 percent monthly, with more than 50,000 bookings processed through its platform, of which 10,000 alone were made last month. He also noted that KidPass achieved a $1 million annual run rate in 11 months and $2 million in just four months.

There are three plans available, starting at $49 per month and going up to $99 and $189. The difference is in how many credits you receive, how many days they can roll over, and how many children can use them. KidPass’ highest plan also comes with a concierge service. There are no contracts.

Parents can search for activities by age, category, and location, or look through curated tips made by the KidPass team. Once you settle on an activity and select the date and time, you’re all set. The idea is to make the activities more affordable than they would be if you went directly through the provider. Liou explained that businesses will provide discounts to KidPass members as an incentive because they “want the exposure to new families.”

The service is currently only available in New York City, but Liou said that there are plans to expand nationally later this year. The company plans to raise additional funds to spur that effort shortly. Possible new markets include Los Angeles, Boston, Chicago, San Francisco, and Washington, D.C.
