In 2019, we celebrated our 20 Year Anniversary and our incredible journey from a start up to a global market leader with over $8 billion of completed transactions, more than 3.6 million registered buyers and over 13,000 sellers from across the globe. Our vision to deliver a Better Future For Surplus for our buyers, sellers and the planet has been reinvigorated through our continued delivery of innovative solutions to our customers driven by technology and data. This year we launched our enhanced LiquidityOne platform that leverages powerful marketing technology and new services such as our Scan-n-$ell app and Seller Self-Service to support our customers and scale the reach of our platform.
During 2019, the execution of our RISE growth strategy, focused on four key pillars: Recovery maximization, Increasing sales, Service expansion and Expense leverage, continued to deliver strong benefits. This strategy delivered more efficient operations, more effective asset promotion to drive higher recovery, a broader choice of seller services, and an increased flow of assets from sellers. As we look to our next 20 years, we remain committed to delivering strong growth while never forgetting the importance of our core values of Integrity, Customer Focus, Relentless Improvement, Innovation to Support Leadership, Mutual Trust and Accountability, Shared Success and Doing Well and Doing Good in our communities.
