Our moms taught us to share.
Because so much of our efficiency comes from open-source sharing and re-use of successful code modules, we believe in the power of open source. So much so that we frequently share our own code with other developers; yes, even our competitors.
We know .NET inside and out.
Microsoft's ASP.NET is a framework for application development which serves as a foundation upon which Agile teams may build web sites, web applications, web services, smart client applications, and even Silverlight animations. .NET custom software may be built in a handful of languages, but the industry has standardized around C# (as has Headspring). Headspring has chosen to make .NET Agile development in C# one of its core competencies as the majority of its key players come to Headspring with extensive ASP.NET backgrounds including working knowledge of and substantial contributions to many open source additions which allow for improvements upon or more efficiency with the standard capabilities of .NET.
