Well, thank you James and thank you everyone for joining us today. We are pleased to report another record quarter and the best fiscal year in our history. There is a lot of highlights, but just a selected few. Total revenue grew 33% over the fourth quarter last year, exceeding the high-end of our guidance. Full year revenue increased 34%. And if you take out small business, which is now less than 6% of revenue, we increased 38% in the fourth quarter and approximately 40% for the full year. And we generated nearly $31 million of operating cash flow in the fourth quarter alone, which is by far a record for us. And we are reporting our first full year of positive operating cash flow, an important milestone as we prove the power of our business model. This quarter, we signed 128 new enterprise logos. Now, that is an astounding 68% increase from the fourth quarter of last year and it's our best quarter ever for new logos. The strong close to the year was also reflected in the very strong growth of our deferred revenue which Steve Cakebread will detail in a moment. Our momentum has never been better and the best-known brands around the world are choosing to work with Yext, including this quarter new logos like NewYork–Presbyterian Hospital, Allegheny Health, Adidas, Nationwide Insurance, PNC Bank, Dunkin' Brands, Chick-fil-A, Chipotle and many, many more. And we also signed renewals and expansions with Farmers Insurance, T-Mobile, Marriott, Tesco in the United Kingdom, Denny's, Panera, 7-Eleven and many, many more. For instance, one of the world's largest banking and financial services firms, it's in the same tier as the Morgan Stanley, signed a major expansion with us, three times their previous contract to go broader across their organization with more products and services from Yext. Given our strength in the quarter, we entered the year feeling very positive about the state of our business and the size of this opportunity. The Internet today is an incredible resource and it provides vast amounts of information. For every query you can think of, there is a dizzying array of results. But all too often, this results in too much information and not enough verification. Consumers looking for answers about a brand or its product don't have a way to distinguish fake from fact or bad information from good. Their questions deserve verified answers that are easy to get. With Yext, brands can enable a single source of truth online to ensure accurate answers are provided to consumers' questions. When your search for information starts with a question like, is this particular menu item gluten-free, you should expect to get verified answer back. Not a guess from a third-party who really doesn't know the answer. That just makes sense. Yext is uniquely positioned to provide brands and consumers with brand verified answers. As of January 31, our customers were storing more than 185 million authoritative facts in our platform. That's an increase of approximately 50% from a year ago. Now to put this in perspective, our customers have added, on average, more than 172,600 facts into our platform every single day for the past year. Before this quarter, we have been periodically reporting attributes like, when a customer provided information to us such as their hours of operation we counted that as a single attribute. It didn't matter how much information was provided. Everything in the field was aggregated together as one attribute. But the actual amount of information that our customers have been giving to us was much greater. So now we are tracking the atomic level of this data and we call that facts. If a customer gives us opening hours from Monday through Friday, that's five facts. If they us what school they went to and when they graduated, that's two facts. Facts are the foundation of verified answers. And when consumers have questions about a business, increasingly they are getting verified answers from Yext. Recently, we did a study on how the consumer experience has changed. We looked at a global example of hundreds of thousands of customer locations and compared the ways that consumers interacted with those businesses in 2018 to how they did just a year ago. The results were stunning. In discovery, customer actions with knowledge cards, that include clicks to call and clicks for directions grew more than 20%. In the transaction stage, customer actions on local pages, like booking appointments or placing orders, they were up 30%. In the post transaction stage, this is new reviews per business location, they increased an incredible 87% compared to the prior year 2017. And this means the acquisition funnel is no longer a company's own website exclusively and that's why verified answers are becoming critical. The way we see it, there are two kinds of companies, those that structure their data for verified answers online and those that will. In the search for truth, Yext provides brand verified answers. If the Internet and AI powered voice assistants are going to review information about a brand that doesn't come from the brand's website, that information should be verified by the brand, period. Our mission is to provide perfect answers everywhere. Our purpose is define the chaotic results consumers see today into the verified answers of tomorrow and our vision is to ensure there is a single source of truth online. Our platform has been built to provide billions of verified facts everywhere so that consumers searching for answers can get the truth from the source itself. For more than a decade, Yext has innovated to put the truth online by putting brand verified answers everywhere. We always have now and we always will. Now I would like to turn the call over to our President and Chief Revenue Officer, Jim Steele.
