“Crashlytics was SaaS. Developers would download RSDK. They would put it in their app, ship it to the app store, and then they would pay us monthly. Funnily enough, we actually stayed in beta for quite a while, grew to hundreds of millions of devices, tens of thousands of apps, and had only just started charging when we were acquired by Twitter. We were acquired by Twitter 14 months after we started the company. It was extremely fast in early 2013. As part of that process, they agreed to make Crashlytics free. We ended up actually having to refund everybody who had paid for it in order to get out of the contracts and just make it free.”
