Tell me who you think your customers might be? Or ask ChatGPT what's a good watering hole for them, it will definitely come up with some reasonable guesses.
But sure, I'm working on things for parents/students, home buyers, and DIY heat pump installers.
* Parents/students hang out at schools and are probably a good referral/recommendation crowd
* Home buyers are looking for mortgage comparisons on Google (but that's probably a terrible strategy, since this is a highly lucrative segment to market to, so you should expect high customer acquisition costs)
* DIY heat pump installers will probably look at ads on /r/DIYHeatPumps
