Not-for-profit healthcare crowdsourcing platform Watsi has received a $1.5 million donation towards its business. The amount came from Y Combinator alumnus Humble Bundle, a video game startup that allows users to pay whatever they want for video games while also supporting charity online.

Watsi tells us that with today’s donation, a total of $2.2 million has been raised to help provide access to healthcare services for those that need it. In addition, founder Chase Adam says that Humble Bundle’s donation will help more than 2,000 patients.

The organization has hired former Palantir health engineer Daniel Tse to help oversee its medical program and make sure that Watsi maintains its mission to provide access to healthcare “to every person on the planet.”
