What's the biggest mistake you've made as a founder?

Starting three different products before at least one matured

Hiring lawyers on a retainer before launching a product, lol. Sharing this here so no-one would do same stupid thing I did when I was starting.

Didn't build a audience before launch.

to get lost with all the possibilities we have ^^

Not starting any sooner.

Nothing new to this thread, but not jumping on marketing and sales earlier. If I were to go back, I'd start and/or hire marketers MUCH earlier.

My biggest mistake was to rely on not qualified engineer whole working on the first prototype of the guitar we're making. We had a problem just before showing it on the conference, as the prototype didn't work! We have managed to find a good engineer after this fail.

Be more resilient and focus on only one product

Biggest mistake was get a technical co-founder who had stopped coding in his career a long time ago. He may not be needed to code, but he is the final bastion if all code breaks down, (and it inevitably did)

everything i do is a mistake, just trying to learn 😂
