That said, and I know this is said a lot, but I really wish our industry would stop trying to label everything a "startup". Automattic was founded in 2005 and has 1000 employees. It's not a startup, it's a mature medium size tech company. Its problems are not startup problems, they're mature medium size tech company problems. Automattic isn't even a clear underdog considering the dominance of WordPress.
To be clear, that's not a pejorative: Automattic kicked ass, and Automattic deserves its current success. But the phrasing is a sticking point for me in how people talk about tech companies because it ends up feeding into how we perceive working at these companies. When I was job searching, I saw job postings regularly where "startup" or "like a startup" are used to invoke a cultural image for companies that are already post-growth-stage.
