Thanks, Mike. Good afternoon, everyone. After another strong year as a public company, I'd like to start today by revisiting the algorithm we use to achieve sustained long-term growth. Our model includes, first, expansion with our existing clients, second, annualization of clients signed the prior year, and third, revenue from clients signed in the current year. We are also adding new payer and non-client services as a fourth component that feeds our annual growth. Our growth starts with expansion with existing clients, which is driven by our primary focus on delivering exceptional solutions and service for our clients across all of our verticals. For fiscal year 2023, we recorded net revenue retention of 125%, continuing in a favorable range denoted by the 123% three-year average between 2019 and 2021 we shared at our Analyst Day, and the 124% we reported for 2022. Our technology and client service teams are obsessed with meeting our clients' needs. Their hard work and our new solutions allow us to earn clients' trust, deliver client retention that exceeds 95% per annum, grow clients effectively, and produce a net promoter score in the 60s. Next in the growth algorithm, we benefit each year from the annualization and growth of clients signed in the prior year. As Mike mentioned, we signed over 700 clients in 2023, including over 170 in the fourth quarter. Our expected revenue per client signed in 2023 remains strong, and as usual, we only realized a fraction of that revenue last year. In 2024, based on our track record of positive client experiences, we expect to benefit from both a full year's revenue from these clients, as well as further penetration of our clients' payers. Third in the algorithm, we recognize a portion of the revenue from new clients in the year we sign them. We invest in our go-to-market capabilities to maintain our long-term growth. We estimate that our penetration of the total addressable market across our four verticals is in the low single-digit percentage range. We see opportunity everywhere and plan to continue to build go-to-market teams to capitalize on these opportunities and increase our market share. Finally, as we address the needs of payers in our ecosystem, we have begun to generate meaningful revenue that is not associated with any particular client. For example, as we grow our pay-any-school capabilities rapidly, we recognize revenue from tuition paid to schools that are not Flywire clients. In other examples, we are helping students procure other needed services, such as student health insurance required in Australia, and with moving money from India to cover living expenses outside of tuition. We are excited to layer in payer services to our solution set and believe there can be a multi-year roadmap in this area. Next, I'd like to briefly discuss how we grew across our four verticals during the fourth quarter. In our education vertical, we estimate our TAM to be about $660 billion. This TAM includes U.S. cross-border education, international cross-border education, and domestic education both in the U.S. and internationally. It includes higher ed, K-12, trade schools, summer programs, and more. We are penetrating our TAM through broad integrations with best-in-class enterprise systems, as well as deeper relationships with education agents prevalent in international education. We are also expanding our TAM by offering new solutions to payers and schools. During the fourth quarter, we signed several new clients in our U.S. cross-border and domestic subsegments, as well as across Europe, Asia Pacific, and Latin America. Recently, we went live with our domestic solution at Adelphi University, a private university based in Long Island, New York, with over 7,500 students. Adelphi had been a cross-border education client of ours since 2013, representing another example of where we had been able to leverage our trusted relationship that originated with our cross-border solution to expand into a much broader offering. For our U.S. cross-border segment, we went live with Florida State University and Oklahoma State University. Outside of the U.S., we went live with George Brown College. George Brown College is a publicly accredited top 10 research college in Canada with nearly 27,000 full-time students. We are now live with both our cross-border and domestic education solutions. GBC chose to work with Flywire to add more payment options, enhanced functionality support education agent-related payment flows, and top-notch customer support. George Brown was one of the education clients that was signed in Q3 but went live after the peak season. All delayed education implementations that we referred to in our Q3 call have now gone live. In healthcare, we estimate our TAM to be about $500 billion, and we are serving many of the largest U.S. hospital systems. We are expanding how we work with partners in this channel to provide deeper integrations and even more flexible affordability solutions. We are also expanding into specialty subsegments. During the fourth quarter, we went live with OrthoNebraska, a specialty hospital based in Omaha, Nebraska, focused on orthopedic care. In implementing Flywire's payment solutions, OrthoNebraska saw nearly 80% of all payments come through the patient self-service portal. Flywire's solution has helped the specialty providers significantly reduce staff hours spent on manually reconciling payments and has received high patient satisfaction scores. Overall, we are seeing early traction in new subsegments of the healthcare market as our receivable software solution helps reduce outstanding patient balances and increase collection rates for specialty hospital providers. In travel, we estimate our TAM to be about $530 billion. We have categorized our clients as destination management companies, or DMCs, global travel operators, and accommodations providers. During the fourth quarter, we signed new clients in each of our existing subsegments. We are also exploring new areas of focus, such as ocean experiences and niche online travel agencies, or OTAs. Recently, we went live with Aqua Expeditions, a luxury travel company specializing in small ship cruises in remote and exotic destinations, such as the Peruvian Amazon and Mekong Delta of Vietnam and Cambodia, along with yachting experiences in Indonesia and the Galápagos Islands. Integrating with Flywire has helped Aqua Expeditions streamline their accounts receivable payment reconciliation process, enabling faster payment notification and funds disbursement capabilities. We are excited to tap into this new subsegment of travel and expand with ocean experience providers around the world. Finally, our B2B vertical covers a broad TAM estimated to be about $10 trillion, where we focus on providing mid-market enterprise clients with a sophisticated and integrated accounts receivable solution. Although starting from a smaller base currently, our B2B business is our fastest growing vertical, and we believe has a very promising future impact for Flywire. Within this massive B2B TAM, Flywire is gaining traction in various subsegments of the market, including insurance, software and tech, manufacturing and distribution, franchises, and others that include the public sector. We recently went live with the European Union Aviation Safety Agency, or EASA for short, which is an agency of the European Union responsible for overseeing and coordinating aviation safety across its member countries. Flywire is directly integrated into EASA's SAP instance to ensure a consistent billing and payment workflow with their existing ERP system, with a key benefit being automated payment reconciliation to remove manual processes around accounts receivable. While on the topic of ERP integrations, I'll also mention that we built out and are live with an integration with Workado [ph], a cloud automation and integration platform for enterprises that seamlessly connects to widely used enterprise accounting systems such as SAP, Sage Intact, Microsoft Dynamics 365 Business Central, Intuit QuickBooks Online, and Oracle NetSuite. We believe that further building out our integrations with leading ERP integrators and systems will help us further penetrate our large TAM opportunity. Stepping out of the verticals and moving to our efforts towards efficiency and scale, I would highlight that in 2023, while we grew revenue less ancillary services by 43%, we reduced our hiring by almost 50% in terms of incremental run rate spend versus what we added in 2022. Our paced hiring in 2023 helps drive personnel expenses as a percentage of revenue less ancillary services down by over 530 basis points when comparing 2023 to 2022. We generate these scale efficiencies by working as a very collaborative team that is focused on careful pacing of hiring and managing of expenses. We expect to continue this focusing on managing all expenses, including personnel expense, in 2024 to produce additional improvement in run rate and personnel expense relative to revenue and to improve adjusted EBITDA margin. I will now turn the call over to Mike Ellis to go over our results for the quarter and year as well as provide guidance for 2024. Mike?
