Hi, OP here. I was employee #13 at PostHog, joining as a designer (who now moonlights as a design engineer). I'm responsible for the website. I've been part of crafting the brand for 4.5 years – joined when the company just started monetizing.
There are only two of us who work on the website, myself and a front end engineer. (He was hired to work on the website and doesn't directly work in the product.)
We've spent roughly half of the last six months on this site. Other than our incredible graphic designer, no other resources were brought in.
A lot of our time is spent on brand-related side quests – they're consistently a net positive for the brand. You can see some examples under "Some things we've shipped" at https://posthog.com/teams/brand
This was a passion project of mine. I'm the one who ultimately chose to spend time I did on it. I think what we built is really cool, and I hope it serves as inspiration for other designers to think outside the box when it comes to solving their unique challenges.
Every company operates differently. Yes, many companies do have employees with too much time on their hands. Others do waste a lot of money in advertising. And a lot of companies are stagnating.
But I can assure you, PostHog is none of those.
