Sun Microsystems has significantly enhanced its Catalyst third party referral programme to help penetration into key markets. Also announced is a new developer program to attract new third parties and OEM customers to the top-selling workstation. Under the enhanced Catalyst Programme, Sun is creating a second category of developers called Catalyst Advantage. With immediate effect all Catalyst vendors will now have a single system purchase option with the introduction of each new Sun product family. In addition, all current and new Catalyst vendors are eligible for membership in Catalyst Advantage. Developers qualify for Catalyst Advantage by demonstrating success in their markets through an installed base of 75 to 100 sites and at least five user-references. Sun will review its existing base of over 500 vendors to identify candidates for Catalyst Advantage. Sun provides developers with discounts of up to 40% on its US list prices.
