This stuck out to me too - maybe OP's using product as a catchall for "non-engineers", but with a ratio like that I'd be very curious what kind of bottlenecks the team's facing and what kind of daily work output's being generated.
Yes. I wouldn say our "Product people" are not very traditional product people, you have our bios and focus in the team link in the post and below. Hope that clarifies the doubts. I've also clarified it in the text, and it now reflects the reality better.
What were the 4 product people doing day to day?
