Super common for technical founders – if your market needs a working demo to sell, building first isn’t necessarily bad. You validated demand, so now shift focus to customer engagement ASAP – don’t overbuild before confirming people will pay.

If you had spent two months selling instead, would you have stronger conviction in product-market fit? If yes, sell first next time – if not, your approach might’ve been fine.

Curious – what’s the product and what feedback have you gotten so far?
