Caxy is a Chicago based software consulting and custom software development agency founded in 1999. Ranked top 3 software companies in Chicago by Clutch. Our secret sauce is that we want to make life as a developer fun, rewarding and not a grind. We have a commitment we call "The Caxy Promise." Many jobs in software are characterized by clients or customers making unreasonable demands and managers making hollow promises that all tumble down to developers who are asked to stay up all night to work. We don't do that. Our promise is that you will work on interesting projects using current technology, your clients will get you and value the work, and your fellow team members will contribute just like you are. It may sound crazy, but we have a track record of ending client relationships when the client is detrimental to the team. For our clients, the Promise means we're going to work with you to find projects and work to do that makes sense and supports and catalyzes your business. No more projects that go no where, don't do anything and are a waste of money. Together, this makes for a place that employees and clients stay for a long time. Many over 6 years, a few over 8 years. We'd like you to think this is the best team you've ever been on and stay for a long time.
