I built a product of similar complexity by myself in a few months. It's built for a small but growing niche. After 2 months of having launched I already have about 70 paid accounts and $1.5K MRR with minimal marketing.

It boggles my mind to think people can burn $40K a month before having an understanding of whether what they built has product market fit.

I literally spent maybe a total of $5000 building and launching my product (+ my time, arguably that's a hidden cost but if you're a software engineer founder, that's also a major asset for you) and with 70 accounts we're getting 2-3 feedback and suggestion emails a day and iterating to please our customers and find PMF before I consider taking any investor money or hiring anyone.

Also their actual marketing page sucks. They don't have a particular differentiator from similar products, I don't really understand what their app does... Blargh. :/
