Has anyone here actually built an EdTech micro-SaaS?

I’m genuinely curious to hear from people who have walked this road before.

Education seems like one of the hardest environments to build a business in. You’re not just solving a technical problem. You’re dealing with learners, parents, teachers, curriculum requirements, affordability, engagement and, ultimately, very real social problems that technology alone cannot solve.

I’m currently exploring an idea for an EdTech platform, and I’m very much in the “figuring this out as I go” stage.

The funny thing is, I don’t actually work in education. I’m approaching this as a parent who wants to build something that could genuinely help my own kids learn better.

My thinking is simple: if I can build something useful for my children, validate that other parents and learners find value in it, and eventually make enough revenue to cover things like hosting, APIs and other operating costs, then that’s already a win.

I’m not trying to build the next billion-dollar education company.

I’m interested in the micro-SaaS approach: solve one specific learning problem really well, keep the product focused, charge something reasonable, and let the product pay for itself.

But I know there are people who have already tried building in EdTech and discovered things I haven’t even considered yet.

So, if you’ve built an EdTech product, micro-SaaS, learning platform, tutoring platform, curriculum product, or anything similar:

What did you learn the hard way?
What worked?
What didn’t?
What would you do differently if you started again?
I’d particularly love to hear from people who started as outsiders to education rather than teachers or education professionals.
