Streak as in my CRM/Deal flow Gmail add on? Power user. I'm worried now that our deal flow is increasing in depth and complexity and we have more outside interest if I'll have to ditch it for something "more complete" (reporting/analytics) I think you should keep it brutally simple like you do but how do you tackle that issue? Is that the "Premium Plan coming soon"?
How does Streak work? Is it a browser add on I need to install or does Google let developers create their own hacks? Btw, you should also consider putting up ads of Steak on your website. I misread Streak for Steak, and have been craving for some medium rare steak. I wonder if Streak.com could become the Amazon of steak delivery.
We used Streak for a while too. We moved on after a while seeing no real progress on bringing it to browsers other than Chrome. The main issue for me was that I couldn't check things on the go with my phone/tablet.
We are now delighted users of Base (https://getbase.com/). Great features, super responsive team with very functional mobile apps (tablet and mobile). And it comes from somebody who religiously hate Sugar CRM and Salesforce. We haven't it the limit of the free plan but will gladly pay when we do.
