PROS makes AI-powered pricing and selling software for large B2B enterprises and airlines. The company operates two core product areas: B2B pricing and CPQ (configure, price, quote), which represents roughly two-thirds of the business, and Travel/Airline, which represents the remaining third. On the B2B side, PROS sells price optimization and CPQ tools to manufacturers, distributors, chemical companies, healthcare firms, and technology companies, helping sales teams configure products, generate quotes, and set prices dynamically in real time. On the travel side, PROS serves over 170 airlines and offers revenue management, real-time dynamic pricing, ancillary pricing, and airline distribution and retail tools built around IATA NDC standards. PROS is primarily a SaaS business — subscription revenue was ~$266M in FY24, or about 81% of total revenue, with the remainder coming from professional services and a small declining legacy maintenance stream. PROS goes to market through a direct global sales force, supplemented by resellers, system integrators, and technology partners. The company follows a "land, realize, and expand" strategy, targeting an initial deal of ~$200K and then expanding customers across geographies, business units, and additional modules. Roughly 50-60% of bookings come from existing customers. PROS has set a long-term target of achieving Rule of 40 (revenue growth rate plus free cash flow margin ≥ 40%) by approximately 2027.
