I've been bootstrapping my last project basically all by myself (UX/UI, microservices, devops, mobile apps, etc) for the last 15 months. I'm saying
basically because one of my former (failed) startup cofounders is helping me every now and then with some development tasks.
It's a market data app with a custom technical indicator for a specific commodity. I've found an external commercial team specialised in this industry niche and they're going to start sales in the coming weeks (after the remaining regulatory hurdles are cleared). This is a top-notch sales team working for Fortune100 companies, so I'm doubling down on them for 15 to 50% of the revenue (depending on sales)....
We tested the tool internally for some customers and was an incredible success. People is literally waiting in line to get it... so I'm also arranging external accounting + support teams.
I hope (knocks on wood) it'll generate me x5 to x10 times the salary I was offered in management positions at 2 of the biggest spanish startups (tuenti and social point).
In the coming months I hope to automate everything for all the teams via Slack ChatOps so I can have more free time and start new projects before Christmas...
