I hope I’ve interpreted this question correctly, but I’ve read it as the approach to ‘scaling’ with the business as a founder, and how looking for/working with investors supported that.
I’ll caveat this with the words that many smarter folk have said before me, ultimately imposter syndrome is very real and realising that everyone faces this challenge in many walks of life is a great reflection point.
Speaking to this personally I believe it’s important to be very open to being wrong, and being able to adapt and learn from those with differing levels of experience. Ultimately I think capability to scale is directly tied to openness to be taught. The best investors look for this in the founders they back and it’s a case of finding that fit in the process.
