This is what happens when both founders are not technical. I use the app and it was obvious from day one it’s been designed and implemented by the lowest bidder.
Not necessarily the lowest bidder. It's quite easy for a consulting company that is bad at development to make a convincing pitch to a nontechnical founder as long as they're better at sales than they are at development.
Because a technical person would immediately find all of the glaring flaws and issues with their app and fix it promptly. Unless they’re incompetent. Which might be worse than non-technical.
Attending node.js events does not mean you are technical. A lot of people, I would say most people in my experience, go those events to connect with technical talent.
