The Segment Story
Caldwell: Segment started with something to tell your professor you were confused in class. Software they sold to universities. Then they pivoted to something like a Mixpanel competitor after about two years.
Then they built a JavaScript snippet that sent data to multiple analytics tools at once — so users could compare Segment against Mixpanel. Nobody wanted the analytics tool. Everyone wanted the JavaScript snippet. That became the company.
"There's no universe where they would have made up the idea for Segment. They didn't know anything about analytics yet. They learned it by grinding for years on earlier ideas."
When to Pivot
Caldwell has a simple test. Look at how many growth ideas the founder still has. If they have a dozen things they haven't tried yet — keep going. Try them. Airbnb tried cereal, conventions, everything. They never ran out of ideas.
But if the founder's best suggestion is "maybe we should pay influencers or something" — that's a sign. When the ideas get that weak, it's time to try a new direction.
"When the founder's out of ideas on how to make it grow, that's usually a good time to pivot."
