Product-Market Fit is knowing, not thinking

If you think you've found product-market fit, you probably haven't.

When product-market fit is found, it will be so obvious, so overwhelming, you'll know it.

The data will not be debatable. The retention curve barely looks like a curve at all. Fundraising is stressful only because the round is oversubscribed, new investors keep showing interest, and you've never been in the position of saying 'no' to money.

It's overwhelming in good and not-as-good ways. There were weeks at Plastiq when I could barely sleep due to a combination of fear and excitement. New users streamed in, adopting the product and using it in more impressive, more exciting ways.

There is no guessing when you hit product-market fit. It will be obvious to all who can see your data.
