He never said it was a "success". He only said that business ideas are everywhere, you just have to look. $100 mrr for 50 customers isn't much, I honestly don't know the OP's pricing strategy, but if people find it (in)valuable, they'll justify higher prices. There's no reason he wouldn't be able to get $500/month if his value proposition is high enough to solve a real pain point. What the OP did, was validate that there's a problem and provided a solution. With proper targeting/marketing/pricing, the OP should be able to get at least 1000 customers at $4.99/m or if the value proposition is high enough, even $9.99/m. That's $10k MRR, which is nothing to scoff at.
