ARC Solutions is a small but growing AMS provider located in Washington, DC. One of my clients purchased their original product (the MAP) so I've had some extensive experience using the product and working with the company.
ARC recently secured $1 million in funding from two venture capital firms to help develop their new product, Polaris. I had an opportunity to see a demo of Polaris recently, and overall, I was pretty impressed. The product is fully web-based and takes advantage of AJAX functionality throughout. It has a nicer user interface and seems relatively easy to navigate. Most importantly, they've made some significant changes to the architecture so that organizational and individual membership is managed more elegantly, and financial management is now done via batches.
One of the cooler tools they have is a "screen development" tool that allows the user to create separate screens for editing data, capturing data, and viewing data. This is a pretty big leap forward, as most systems on the market tend to have the same screen for capture and edit, and frequently even the same screen for display of data. Polaris allows you to modify each separately. Very slick.
ARC is seeking further financing and I expect to see a lot more from them in the coming months and years. You can find them at ARC Solutions.
