Thank you, Belinda. Good afternoon, everyone, and thank you for joining us on today's call. I'm proud to share that we delivered a strong start to 2023. We grew subscription revenue by 15% and total revenue by 10%, while delivering a 75% improvement in adjusted EBITDA year-over-year. We're laser focused on fueling our own profitable growth and our performance in the first quarter is a testament to this focus. As a result, we're raising our full year 2023 guidance across all metrics, which will cover in his remarks. Underpinning the success of our team is our platform strategy, we continuously extend our market leadership position by consistently driving new innovations to market through our platform. For modularized capabilities to deliver real quantifiable value to our customers, creating the flywheel effect that is our landing expands sales strategy. At the heart of the PROS platform is our AI. Our AI algorithms have been trained across industries to drive immense value for businesses. We have productized AI algorithms that predict demand, optimize supply chains, drive customer cross-selling, upsell recommendations, detect customer attrition, and predict customer willingness to pay among many others. Our algorithms, not only drive credible value, but are explainable, extensible, and highly scalable. Our explainable AI approach is what drives high customer adoption of our market leading algorithms. Our AI is extensible, enabling our customers and partners to infuse their own algorithms into our platform, bringing new innovations to life. Our AI platform is extremely scalable and supports mission-critical availability to deliver results in real-time to businesses around the globe. To put our scalability and availability in perspective, we're now processing 5.9 million transactions per minute with platform uptime of 99.97%. Annualize, that puts us at over 3 trillion transactions process in a year. That's more than two and a half times the 2022 equity trading volume of the New York Stock Exchange. There has been an acceleration of market interest in AI technology to drive business outcomes, and I believe the growing acceptance of AI will be a long-term tailwind for PROS. In Q1, we launch a new generation of PROS dynamic pricing for ancillaries powered by AI. For airlines, ancillary revenues an increasingly important growth driver, with ancillary revenue as a percent of global airline revenue increasing 40% in the last five years. PROS dynamic pricing for ancillaries uses reinforcement learning techniques to explore and percent ancillary service prices to passengers, aiming to drive more overall ancillary sales at more optimal prices over time. Dynamic pricing for ancillaries extends PROS leadership position in our offer optimization for airlines, along with our digital offer marketing, dynamic offers in digital retail capabilities. In Q1, we made our innovations even more accessible to customers across industries by enabling businesses to embed PROS Smart CPQ solution in a Microsoft Power App. Businesses can now integrate our market leading capabilities with other applications in selling workflows using a low-code no-code development approach, further extending the digital footprint of PROS platform. Now I'd like to talk about some of the incredible new customer lands we had in Q1. Europcar, one of the world's largest rental car companies selected PROS to optimize B2B and B2C selling. Europcar will benefit from our expertise in the rental car industry, using our AI models for demand forecasting, fleet optimization and fleet distribution, empowering them to optimize revenue management and capacity controls. With our pricing and CPQ capabilities, Europcar will also streamline the buying experience for corporate agreements to drive a higher conversion of sales. With addition of Europcar, PROS now powers commerce for three of the top five rental car market leaders globally. We also continue to welcome new customers across areas of manufacturing and distribution. Meyle, a manufacturing distributor of automotive parts selected PROS to optimize pricing and fueled their profitable growth in the wake of inflationary pressure and supply chain disruption. Another example is Nature's Touch, leading manufacturer of frozen fruit, who selected PROS to streamline and deliver market relevant prices to customers around the globe. We also welcome QuidelOrtho, a leading manufacturer of diagnostic healthcare products. QuidelOrtho is beginning their journey with PROS powering high volume quotes to integrated delivery networks and group purchasing organizations. Now I'll share a few examples of expansions from Q1. Air Europa expanded their solution to incorporate our latest innovations in group sales optimization, including dynamic pricing, ticketing and payment capabilities to enable a fully digital end-to-end experience for their customers. With this expansion, Air Europa is now driving value from every airline centric capability of the PROS platform. We continue to see success in the energy space where PROS provide solutions to five of the top 10 largest oil and gas companies in the world. In Q1, we expanded our relationship with Phillips 66, with their decision to migrate to our cloud solution to take advantage of our latest AI innovations for fuel price optimization. A core component of our land and expand strategy is value realization. PROS commission Forrester consultant, part of leading global market research company, Forrester Research to independently interview several PROS customers to access the value generated from the PROS platform. The Forrester Total Economic Impact study showed an investment in PROS paid for itself within nine months and generated a 400% return on investment in the first three years for the interviewed customers. Most enterprise software solutions have a hard time to demonstrate direct and quantifiable value, but this study conducted by Forrester showed once again the direct correlation between PROS solutions and a quantifiable improvement to revenue and margin. We're going to share more about our new innovations and how industry leading companies are leveraging these new innovations to drive profitable growth at our upcoming Outperform conference scheduled for later this month. Outperform is one of the preeminent AI conferences in the world, and we're looking forward to bringing together experts from across industries to discuss how AI can drive business forward. Before I close, I'd like to thank our incredible global team for their passion and dedication to PROS or customers in our communities. I'd also like to thank our customer partners and shareholders for their ongoing supportive PROS. With that, I'd like to turn the call over to Stefan to cover financial performance and outlook.
