They Needed a CRM. So They Built One Inside Gmail.
The year is 2011. Aleem Mawani and Omar Ismail, both ex-Googlers, are going through Y Combinator with their startup. They need a CRM. They try everything. Salesforce feels like filing a tax return. The lighter options aren't much better. So they do what engineers do: they build their own.
The insight was simple enough to sound obvious in retrospect - salespeople already live in their email. Why make them commute to a separate app to log calls, track deals, and manage contacts? Why not bring the pipeline to where the work actually happens? Streak became the answer to that question, and it turned out a lot of people were asking it.
The product launched as a Chrome extension - a deliberate choice that gave them access to 500 million Chrome users through the Web Store, at essentially zero acquisition cost. That channel drove roughly 90% of early signups. By the time anyone in the CRM industry noticed, Streak had hundreds of thousands of users and a quiet head start it has never given back.
"We built Streak because we were going through YC and needed a CRM ourselves. Every other option felt too clunky or required us to leave Gmail."- Aleem Mawani, Co-Founder & CEO
Here's the detail that tends to stop people: Streak was completely free for its first three years. No premium tier, no trial limits, no upsell pressure. Just free. They spent 2012 to 2015 building product and audience rather than monetizing. When paid plans finally launched, Streak hit $30,000 in monthly recurring revenue within weeks - almost entirely on word of mouth. The users were already there, already dependent, already evangelizing.
"We were in YC, building a startup, needed a CRM - and ended up building the thing we were missing instead."
