Is a twenty-something founder going to hire people twice their age in the early days of their company? Unlikely.Twenty-something founders hire people they know, who are usually their own age. Friends from college, or the other twenty-somethings from their last company.
As a early-twenty-something I only know a relatively small number of engineers 30+, and have only worked with a handful. Compare that to the dozens of engineers my own old that I know, and have worked on projects together. If I founded a company tomorrow I know which 4 friends from college I would want on my team, they're all other twenty-somethings.
The only engineers over 25 I have worked with (excluding open source projects) were my bosses at previous companies. I simply wouldn't know who to hire. Anyway, would any self-respecting engineer take a job at a company found by one of their interns or recent graduates from a few years back? I highly doubt it.
In my hypothetical would I really hire someone who was twice my age? Probably not. To be honest I'd be afraid of their experience. I'd feel maybe their my training wheels. They have a lot more experience than me, will their experience take over my company's vision. Part of the mentality as a twenty-something founder is proving yourself, be that to your colleagues, your peers, your parents, or whoever said you just wouldn't make it.
I find it hard to find other twenty-somethings hiring many people twice their age in the early days. Maybe without even realising it a culture similar to that of college creeps in. Every new hire creates culture, and from my hypothetical I don't have a very diverse team to start with if I start with college friends and other twenty-somethings.
Somewhere in the early days no one seems to be spotting the 'culture' problem start-ups are creating. Was this problem unintentionally created? Or was this problem created sub-consciously created intentionally? Would I as a twenty-something founder sub-conciously create a company where my Dad or my even my cool Uncle wouldn't want to work at? Probably.
