Tumbleweed Builds Partner Momentum With New Lead-to-Deal Lifecycle Program

Tumbleweed® Communications Corp. (NASDAQ:TMWD), an industry leader in managed file transfer and email security, today unveiled the Lead-to-Deal Lifecycle program, which is designed to spur the continued growth of the Tumbleweed Alliance Program (TAP). The Lead-to-Deal Lifecycle is a fully integrated component of the TAP and is designed to support and reward partners at every step of the sales cycle – including post-sale customer satisfaction. Designed in collaboration with several partners who piloted an initial program at the end of 2007, the newly minted Lead-to-Deal Lifecycle provides easy-to-use opportunity registration and lucrative margins, as well as new levels of support that help ensure both partner and customer success. Premiere partners who participate in the Lead-to-Deal Lifecycle program receive world-class technical support free of charge and can fast-track their customer support requests. "The Lead-to-Deal Lifecycle program is the best I have seen in a very long time,” said Dave Mast, Sales and Marketing Manager with Precision Computer Services. "This program is going to get our guys excited and drive new business.” With a focus on becoming a channel-driven sales organization, Tumbleweed developed the Lead-to-Deal Lifecycle program to quickly and cost-effectively recruit and enable partners. Partners and their reps are rewarded at every step – from referring a lead and registering a deal, all the way through to closing a deal. In addition, those that register an opportunity still receive margin protection – even if the deal is lost to a different partner. Finally, Tumbleweed’s exceptional technical and customer support helps ensure customer satisfaction and success. "Our channel program is getting more traction each day – our differentiated products and programs are drawing star partners, and we are seeing significant booking momentum as a result,” said ‘channel chief’ David Harris, vice president of worldwide channels at Tumbleweed. "As we continue to invest in our partners’ success with programs like our Lead-to-Deal Lifecycle, I am confident that we will continue to see record gains – and so will our partners. In fact, several have already told us that we were their biggest growth vendors last quarter in both revenue and margin. Our commitment to building mutually-beneficial partner relationships is stronger than ever.” Tumbleweed shifted to a more aggressive channel model in mid-2007, resulting in impressive gains for the year and pivotal growth between Q3 and Q4. Tumbleweed’s channel partners delivered 37% of non-renewal commercial bookings for the full year of 2007, compared to 19% in 2006. Following the re-launch of the TAP in July, partner bookings doubled from Q3 to Q4, and 48% of non-renewal commercial bookings in Q4 were driven through the channel. Additionally, with the partner program in place, Tumbleweed saw a greater number of bookings among small- to mid-sized enterprises – and a 31% increase over 2006. This is a trend Tumbleweed expects to continue. As organizations mature and regulatory pressures move down market, there exist large pockets of opportunity for Tumbleweed’s suite of differentiated products, notably the managed file transfer product SecureTransport™.
