You are correct. I may have mentioned in this thread that I was employee #3 in a Silicon Valley startup in telecomm when that was hot.
Yeah, we struggled and took on al lot of tasks. I built the lab, hired people, designed the optics, all the detection, the feedback loop for stability, performed rigorous testing and calibration and had a lot of input on packaging.
There was however, the understanding that as we grew, we would need to put in place teams from each discipline. It was understood that this (along with gobs of startup cash) was the way to grow and prosper.
Small boutique companies are exciting. One may be enticed by their offerings. Sometimes the ones who started the company want it to remain small. This can be a successful way to run a business if it is kept small. There is always the possibility that because many functions are done by one person, something important might be overlooked. The customer should be aware of this from the beginning.
As a hypothetical, imagine that you've developed a gizmo that you think people may value highly. I contend that it is difficult to remain unbiased when someone else in the company or the customer points out a problem or has some constructive criticism.The "Hey, I designed it so there can't be anything wrong with it" attitude. I've been there before myself.
(This last is from my direct experience with a boutique tonearm manufacturer. I purchased an arm from them. After installing the arm and using it and praising its quality, I wrote an email to the inventor indicating certain places where I thought improvements could be made. I heard nothing back. After I made several attempts to get through to him, I realized that he had probably blocked me.) He just couldn't cope with my constructive criticism. I still have the arm, but it sits in box now.
Multiple disciplines in an organization help to prevent this sort of bias affecting goods developed and sold. There are exceptions of course. These systems may break down. But there will always be consequences down the line.
One can accept all I've written and go out and buy that product from a small company despite my warnings.
The sole reason that I wrote this post is to raise the awareness of possible quality and performance problems with a product that comes from a company that does not have the input that different disciplines bring to product development and manufacturing. The old "caveat emptor".
