I've been building SaaS since 2008 and built two with Go. Big spoiler, the technology you choose has a little impact in the early stage of a software business. There's some danger to over-engineer and use complex construct while you still does not even know if what you're building is desirable. Heck, you don't even know what you're building at first.
I'm giving some example of common traps and pitfails technical founder tend to fail into when jumping into a startup venture for first times. And yes, times is plural, because it takes multiple attempt before learning lessons.
