What I was meaning is actually not about external investors or so. My point is, sometimes even putting more equally competent technical collaborators won't work; it's like digging a tunnel: the working surface is only that wide, an extra worker can do little more than staring at the working man's ass.
A typical woodhead's thought. "Accelerate your business's growth". Hahaha. Hard things have to be done solo because explaining to others is slowwwwwwww.
Yes you could get things done most of the time without knowing it, but why bother? It is not hard to learn and you'll need it anyways someday if you code enough.
