How can PMMs adapt GTM plans as early assumptions break down after launch?
Lately, I’ve found myself revisiting GTM docs I wrote just 6 weeks ago — and questioning half of it.
Most GTM plans are built on early signals:
👉 A few conversations with users
👉 Feedback from beta testers
👉 Initial market research
But then you launch.
Your assumptions meet reality — and sometimes, they don’t hold up.
Your ICP starts looking different
The messaging that resonated in interviews falls flat
So the real question is:
How do you integrate what you’ve learned — without rewriting everything from scratch?
