The Company/Work Environment: 
We build tools. Tools that are useful, simple, and efficient. And that people love to use. We’ve been around since 2001, and have been profitable since day one. We work like we’re a startup. We’re small, nimble, and fast-paced, but we’re not pulling all-nighters and burning VC money either. If you have an entrepreneurial spirit, and like working for a company where you can actually make a difference (but you also want a personal life), that’s us.
