Looking back, it was really easy to build something like a domain name recommender 15 years ago or online calculators and such 10 years ago and mailing list tools 5 years ago. I had the skills for doing all of these at the time. Now is the next best time. Although I work in tech, I struggle to find small niche ideas that require very little marketing (SEO driven) and take 3 weeks to build, ship and launch. It doesn't seem so hard. Am I looking for Unicorns?
Ask for pain points and their workarounds, not peddle your solution.
Let's say they value their time at $30 an hour. You build something that helps them shave an hour a month. Some will definitely pay you that much a month.
On this note, consider there is a huge, very often understated, leap between "Oh, this is cool" and "Here's 20$".
The discipline needed here, particularly by us developers, is to recognize the absolute core value proposition and to do just enough to validate it.
In the beginning, it might just be you and a sloppy script you write. No SaaS, minimal website. Your customer would have to email you to get anything done.
Once you get paying customers like that, you automate it gradually, and build out your SaaS.
Seems pretty hard to me. It's generally easy to come up with an idea. It's much harder to actually make money with one (in my experience).
I tried to monetize an Android app with ads and a paid version. I could never gain enough users. I had a second app with more users, but didn't want to clutter it with ads. Of course that one actually had a decent number of users, but infrequent use (designed for utility, not monetization).
Nôt sure if it helps you
