ReadMe.io launches out of the W15 batch of Y Combinator:  


“With the prevalence of APIs, it’s easier than ever to integrate features from your favorite apps and services into your own work. If you’re one of those companies looking to get your APIs in the hands of third-party developers, however, it means that you’ve got more competition for mindshare.

How do you get developers to integrate your maps or restaurant review database instead of someone else’s? The obvious answer is building out a stronger showing of features — who wouldn’t go with the most powerful option?

But as Stripe’s rapid growth has shown, even in a market where the feature base is relatively stable, making it easier to deploy your technology can go a very long way. Stripe’s documentation makes it easy to use their APIs for handling payments whether you’re a lone blogger who wants to try a subscription model for their site or a startup scaling up to millions in sales.

Y Combinator-backed ReadMe wants to make it easy for any company to provide quality documentation for developers who might be interested in using their APIs.”
