As a founder of a few software startups, I agree with this. If I can give advice to other founders, remember than software is usually a means to an end, and for most users, they just want the bare bone essentials to work and work well. Everything else is nice-to-have-fluff that won't drive 99% of sales.
The apps I pay for are simple and focus on a super basic interface. BookFusion and Libro.fm are great examples.
It’s interesting because my experience is inverse (b2b software) - the bloated shiny solution what actually doesnt work at all performs better in the market than the sober, unsexy solution that just works.
Companies like Oracle or Microsoft are so massive not because they sell simple and focused products that work well; quite the opposite
Might be different when you’re selling to endusers
