“From those three to five domains you're going to look for niches that already have successful SaaS tools. If they're already making money, that means the market exists. The key here is that you don't need a unique idea — you're just going to execute better in a proven market.”

Once a niche has incumbents pulling real revenue, the only remaining job is to out-execute them with deeper domain knowledge or a tighter partner channel.
