DotNetNuke Corporation, the owner and maintainer of the open source web application framework that goes by the same name, has raised an undisclosed amount of Series A venture funding from August Capital and Sierra Ventures.

DotNetNuke is a web application framework written in VB.NET, and is used by developers worldwide to create, deploy and manage interactive web, intranet and extranet sites. Its DotNetNuke.com community website has over 630,000 registerered members, and the open source framework (the application is licensed under a single BSD open source license) has been downloaded over 5.5 million times to date.

Details about the amount of funding were not provided, but a blog post on the community site by Shaun Walker (the original creator of DotNetNuke and President/Chief Architect of the corporation) reveals that it took DNN 18 months to close the financing and that it ultimately reflected the ‘market rate for a project of their size and stature’.
