Daniel Slage, Developer/Engineer/Partner
825 Chicago Avenue Suite 2D | Evanston, Illinois, 60202 Dont get us wrong.
We can more than hold our own in a room full of engineers and can talk in acronyms like the best of em. However, those guys dont usually hire us; you do - to overcome internal and external business challenges.
Plain speaking and elegantly small by design, our approach to application development is that common sense practicality makes it possible to help our clients without inflated budgets, scope creep, and long delivery timelines. Founded in 2001 by Dan Slage and Lawrence Neisler, Steadfast has developed mission critical intranet/ extranets, custom web-based software applications, and hosted enterprise Email for healthcare, business, and non-profit clients. We are experts in application development, web security, and hosting mission critical data on a 100% uptime service model and have also developed many public websites in partnership with our marketing group, Wilburn Thomas.
Have an idea? We can bring it to life and even take you to market with go to market planning, strategy, and brand development.
