K2 blackpoint® is for SharePoint users who want visual tools to build workflows and process-driven applications quickly — without code, without complexity.
K2 blackpoint has a powerful Office-style designer (K2 Studio) and a Silverlight-based K2 Web Designer that provides profound simplicity. Non-developers and business users can use K2 blackpoint to create new SharePoint workflows that span libraries, sites, InfoPath forms, server farms and organizations; manage approvals; and route documents and list items. With K2 blackpoint, everything is visual and wizard-driven, everything can be built without code, and users can assemble new applications from information that already exists.

As the flagship product, K2 blackpearl® is the most extensive and feature-rich software for building process-driven applications across the enterprise.
K2 blackpearl design surfaces — browser-based, or hosted in SharePoint, Visio and Visual Studio — are appropriate for a broad range of users and technical-skill sets. And because the process definition is not tied to the designer, users can collaborate regardless of their technical skill or preference.
With K2 blackpearl, everything is visual. Everything is declarative. Everything is reusable. Everything is intuitive.
