Pretty good! Relatively small team (between 10 and 100), biased toward senior with a few ~5 year more intermediate people, mostly remote across the US although we do have an office and try to get together monthly to quarterly. Ironically, lots of open source contributors. We are hiring for a few roles but mostly just being opportunistic rather than needing to hire. Remarkably little turnover for a tech company. We've all worked at multiple other places made the conscious decision to make this a good place to work.

Biggest challenges are supporting multiple platforms (iOS, Android, Web), all the backend infra, etc at scale with a small team -- i.e. normal startup stuff. Also the perennial challenge of doing new features vs. making things more robust.

A lot of info in the SEC filings as well as news articles (many of which are predictably biased for partisan reasons).
