Earlier this week, Union Square Ventures announced that it was leading a Series A investment in an online education marketplace targeted at K-12 students. The platform is called Outschool, and you can think of it as a form of homeschooling.
Today, there about 55 million K-12 students in the US, with around 9% enrolled in private schools. Charter schooling is on the rise (somewhere around 3 million students), but so is homeschooling (similarly around 2.5 million students). Data here.
Homeschooling, at least in the US, largely started within religious groups. But that is starting to change and it is becoming more widely adopted. USV has made a bet that this trend will continue.
If you look at Outschool's model, you'll see that it shares a lot of similarities with other successful internet marketplaces. It is direct-to-consumer (the internet has a way of getting rid of intermediaries). The courses are significantly cheaper than traditional classroom schooling ($10-15 per course). And the supply-side of the marketplace (the teachers) is far more open and accessible to non-traditional participants.
