I known the HubSpot co-founders, Brian Halligan and Dharmesh Shah, since July of 2006. And from a cheap row seat I’ve watched them take the company public, and grow it from just them to close to 4000 employees. And even though I think I know the story pretty well, and have spoken with both of them throughout the years for this series – the last time being four years ago with Dharmesh at the companies Inbound conference – I always learn something new about what they’ve done and how they’ve done it. That continued earlier this week when I had a LinkedIn Live conversation with Dharmesh.

Now, Dharmesh doesn’t do a ton of these, so I was really glad he joined me and shared a number of things during our discussion. Below is an edited transcript of a portion of our conversation, where he talks about the early days of building the company, why the partnership with Brian has been so long lasting and successful, and why a guy who describes himself as an introverted tech geek decided to write a culture code that has turned into, as he puts it, one of the greatest contributions to the company.
