Founder of Streak here and, as you pointed out, we authored the InboxSDK. Just to clarify a few things, our market is actually great, the CRM industry is huge and we do very well in it - we're profitable! As for why we made the SDK, we're not "branching" out - we made this for ourselves because we needed it. We built a bunch of tech to wrangle Gmail and the way we engineered it is we separated it from our main business logic. We didn't want others to have to go through what we did (reverse engineering a lot of gmail) so we made it available for anyone to use. We don't charge for it and we maintain it for free. Several large companies (Dropbox, HubSpot, etc) depend on this SDK to power their Gmail integrations so it's not just small and medium sized companies. Your comment was a bit harsh, but I guess that means we need to address this stuff better on our website.
