I've worked for both types of companies. It's surprising that both cultures work in their own context. At the startup I worked where the dev process was zero, we were able to flesh out pivots and products at a pace that was able to bring continuous investments to the company. To be honest I didn't enjoy the craft though during that time. There was no depth, but a lot of breadth. It was just about churning out code like a machine. At the bigger company where I work now, money stopped being a factor. I was able to afford time to ask fundamental questions about my code. My code was reviewed and shipping was governed by a process that scrutinized devs. Slow and sometimes frustating, but still enjoyable given the freedom of time I was now given. At any day, I'd pick working for a large-ish company than a early stage startup unless it's a startup that makes things I care about.
