Houston, Texas – July 30, 2007 – PROS Holdings, Inc. (NYSE: PRO), a leader in pricing and revenue optimization software, and Advanous, a provider of pricing and margin management solutions exclusively for the distribution industry, today announced a partnership to offer a more comprehensive solution set to improve margins and revenue growth for distributors.  PROS and Advanous already serve many of the distribution customers that have implemented third party pricing software.  The new PROS-Advanous partnership will focus on offering added value to distributors, regardless of size or infrastructure, by delivering industry pricing best practices in software as well as thought leadership based on their experience gained across multiple segments of the distribution industry.

“PROS and Advanous have a wealth of experience in the distribution space,” stated Jeff Robinson, PROS Senior Vice President of Pricing Solutions.  “Pricing is a major area of profit leverage within distribution companies: margin improvements can translate to huge returns. This partnership will allow us to leverage our combined experience to deliver best-in-class pricing solutions.”

“Distribution is an industry which, in our opinion, has been largely underserved from a pricing standpoint,” added Erik Bleyl, CEO of Advanous.  “Many vendors do not fully comprehend the complexities and unique pricing challenges that distributors face.  PROS and Advanous understand these distributor challenges, having successfully implemented many effective pricing solutions. We are excited to partner with PROS to help distributors capture prices that truly reflect the value they provide to their customers.”
