"I'm afraid if I enter a niche that I'm not familiar with ex. "Invoicing for Architects" I will have no idea and I'll probably have no passion for it." Are you passionate about Time Tracking? You seemed to rule that out and others based on a crowded market, not lack of passion (if you really are passionate about time tracking you're a weird dude). I'd suggest either telling us about what you actually are passionate about and maybe somebody can suggest a way to build an app within that vertical. OR... make building a successful business your passion regardless of how mundane the pain point is that your SaaS addresses. Even if you do attack a vertical you might not be passionate about how much time will you spend past initial development in the minutiae of the niche? More likely you'll spend time writing code, tweaking landing pages, sales funnels, other marketing, etc... Can you channel your passion into that?
