TL;DR: is it time for our startup to build a real hiring & onboarding organizational process even though the entire process might become irrelevant in a few months?

We’re a 10 FTE almost $1M ARR bootstrapped SaaS that’s been growing rapidly (20% MoM). And although the growth is great, it’s also taking a massive mental toll on me and everyone in the company and causing our wheels to spin to a critical level.

I’ve typically been extremely slow to hire and quick to fire, but now we have 10+ vacancies and about half the time I had before to do the interviews. So I’m unsure if I can keep the same mindset moving forward and be able to fill up the vacancies in a timely manner.

I’ve been thinking about bringing in a part-time recruiter and building up internal documentation and processes to make the onboarding easier. The problem is we are growing and changing so quickly that I’m not sure if it’s a good idea it since most information will be irrelevant in 6 months.

I’d be really eager to hear about similar experiences. I’ve tried looking around for best practices for companies in similar positions but couldn’t find anything relevant.
