–I believe this was mentioned by another reviewer already, but this is a startup agency in high-growth mode and that comes with some challenges. Projects are often demanding with tight turnarounds/staffing/budgets. If you're cool with that, and you’re familiar with the ebbs and flows of startup culture, the rewards are plentiful — great projects, inspiring clients, fun and supportive colleagues. If you’re not, walk away.
–No physical office: A “pro” for many people, but it was a “con” for me.
–As with most small companies/employers, it can take a while to move up in title/role. There just aren't clear/established paths to promotion yet. That said, opportunities for growth do come in other ways.
