I'm doing exactly this. Making a consistent income from a fairly hands-off fintech startup, but wanted to leverage my time so am working full-time in a related area.

Made full disclosure on all my interests and activities with my employers before I joined a couple of months ago. To my surprise they didn't see a problem. It's understood I cannot take part in anything that might lead to a conflict of interest.

Long story short: it can work fine with good will on both sides. But do be completely open about what you are doing. I got a statement, in writing, that my outside interests would not cause a problem and suggest you do too.

That sounds interesting! Tell me more about how much time and involvement you have with your startup, please. Hours per week? Other employees? Free time? How long have you had the startup for, before starting work?

I'd been working on the startup full-time for 2-3 years. Software is complete, tested and documented. Design is robust enough that I hardly ever get support calls or emails. So rather than watch daytime TV I thought I'd go back to a full time job for 6-12 months. I could live off what the business brings in but would rather earn some extra $$$.

It's been a very positive experience - working on a different set of financial issues is feeding back into future enhancements for the system. Will probably go back to support/R&D when we get some more sales.
