I ran a profitable company for about 7 years, but I didn't have product/market fit. It was always pulling teeth to find users. After I decided to call it quits with that first one I started on the career developer path until coming back to building my own thing.
One thing that was extremely clear was that the products I worked for that did well, very clearly had product/market fit.
Marc Andreessen said: "You can always feel product/market fit when it’s happening. The customers are buying the product just as fast as you can make it — or usage is growing just as fast as you can add more servers." every successful business I worked for has had this be true for them.
Growth is organic. Direct traffic/branded keywords made up well over 80% of signups. My goal now is to find product/market fit at all costs. If that means throwing out everything I've done once it's obvious I'm not there and pivoting hard, I plan on doing it. I've been doing a lot of research lately on how to measure and find product/market fit and thought I would share a cumulation of the more interesting resources I found.

Hopefully it's helpful. I would love to hear your journey to product/market fit too!
