Honestly, I think it depends on your company's financials. If you have a healthy ARR topline and have been profitable with solid margins, practically there ain't any reason to source funding. But then its a also a question about how fast you wanna grow your company - whether you're happy with gradual and steady growth or want to desperately blitzscale!
But I think the main problem is can you cold start without VC? I've a side project and I'm trying to figure out whether to spend time meeting VC and raise funds or just execute + build product.
If I were doing it I'd set out to do everything in my power to bootstrap and own 100% of the company. I think that's the easiest it's ever been for the reasons you say and because of cheap cloud resource. I'd use VC as a last resort or if I genuinely needed to accelerate development or growth for competitive reasons.
