Thanks, but I meant more in a tactical/practical sense. What channels do you tend to use to look for those people and contact them?
First step is guessing who your customers might be.
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
