Thank you, Erica. And welcome to everyone joining us on the call today for Appfolio's fourth quarter and fiscal year 2018 financial results. We had a strong fiscal year 2018 with full-year total revenue of $190.1 million, a 32% increase year-over-year and full year GAAP net income of $20 million or $0.56 per diluted share compared to $9.7 million and $0.28 per diluted share in fiscal 2017. Included in our 2018 results, is revenue of $400,000 and net loss of $1.4 million attributed to the acquisition of WegoWise. Also included in our fiscal year 2018 results is $6.3 million of non-cash charges related to stock-based compensation. For those of you who track non-GAAP results, our Form 10-K was filed today and includes more detailed financial data points that you may find helpful in calculating non-GAAP results on your own. In addition, as previously disclosed we adopted ASC 606 using the modified retrospective method on January 1, 2018 and our Form 10-K provides the reconciliation of the impact of the adoption on our current year results, which may be helpful. When comparing to prior year results. We ended the year with approximately 13,050 real estate property manager customers, managing an aggregate of 3.91 million units in their portfolios, compared to approximately 11,700 customers and 3.25 million units under management reported a year ago. The year-over-year increase in the average size of net new customers acquired is the result of our continued efforts and success acquiring higher unit count customers. As a reminder, we define our real estate property manager customer base as the number of customers subscribing to our core solution. Legacy legalized customers and the related units are not included in our customer and unit count. In the legal vertical, customer count increased 10% year-over-year to approximately 10,300. As of December 31, 2018 our annual dollar based net expansion was 116% for our property manager customers and 113% for our law firm customers. This compares to 112% and 113% respectively in fiscal 2017. I encourage you to visit our 8-K filing today for more information on how we calculate annual dollar based net expansion. Turning to the fourth quarter, we reported total revenue of $50.4 million, which represents a 33% increase year-over-year and GAAP net income of $2.6 million or $0.07 per diluted share. Included in these fourth quarter results is $1.9 million of non-cash charges related to stock-based compensation and approximately $800,000 of net loss related to the WegoWise legacy business. As a reminder, we expect the acquisition of WegoWise, will serve as the building blocks for a utility analytics and management Value+ service that will be offered to Appfolio real estate customers in the future. Core Solutions revenue was $19.4 million in the fourth quarter, a 26% increase year-over-year primarily due to a 20% increase in property manager units under management related to 11% increase in the number of property manager customers. Fourth quarter Value+ services revenue was $28.8 million, a 38% increase year-over-year. Revenue from each of our Value+ services increased year-over-year with the majority of growth derived from increased usage of electronic payments, screening and insurance services by a larger base of property manager customers and a higher number of units under management. Turning to expenses, total costs and operating expenses for the fourth quarter increased 34% year-over-year on a GAAP basis compared to an overall 33% increase in total revenue. Our year-over-year increasing cost is primarily related to incremental third-party costs associated with the delivery of our Value+ services, additional headcount growth in support of our growing product offering and customer base, performance-based incentive compensation recorded during the period, increased professional service fees associated with expanded audit services due diligence and acquisition-related activities and increased facilities expenses and other costs to support our overall 36% increase in headcount year-over-year, which includes employees that joined the Appfolio team via acquisition. We continue to expect that cost and operating expenses will fluctuate from period to period, as we evaluate and invest in growth opportunities including expanded product offering, new Value+ services, adjacent markets or new vertical markets. Moving to the balance sheet, we close the fiscal year with approximately $102 million in cash, cash equivalents and investment securities and $48.6 million of long-term debt. During the fourth quarter, we generated a $11.7 million from operating activities drew $15 million from a term loan issued late in the quarter and used $21.6 million to repurchase shares of our Class A common stock. We also use $400,000 to purchase property and equipment and invested $3.3 million in additional product innovation via capitalized software. Following the close of the year, we used approximately $54 million in cash for the acquisition of Dynasty Marketplace is a leading provider of our advanced artificial intelligence solutions for the real estate market. We believe the acquisition of Dynasty strengthens our system of intelligence capabilities and lays the foundation for AI based Value+ services over time. Like WegoWise, Dynasty related revenue will be included in other revenue unless our customer is using our AppFolio Property Manager or AppFolio Property Manager Plus as their system of record at which time we would include the related revenue as part of our Value+ services revenue. On February 28, of this year, our Board of Directors authorized a $100 million share repurchase program. The program allows for repurchases at prices that are below intrinsic value conservatively determine but does not obligate the company to repurchase any specific dollar amount or number of shares and may be modified or suspended at any time. We have not initiated any repurchases under this program as of today. The $100 million repurchase program includes any remaining amounts available under our prior repurchase program. To recap our results for the fiscal year, total revenue increased 32% year-over-year to $190.1 million and GAAP net income of $20 million or $0.56 per diluted share. We are pleased with our results and continue to focus on delivering great software and services that meet the needs of our growing base of customers. As we look to 2019, we expect full-year revenue in the range of $250 million to $255 million which represents year-over-year revenue growth of 33% at the midpoint of the range. We expect our weighted average diluted shares for the full year to be approximately $36 million. We expect to continue to invest in growth opportunities that we believe will positively impact long term stockholder value including APM plus utility management and real estate related artificial intelligence services. In addition, in support of our growing employee base, we expect an increase in facilities related capital expenditures. As a reminder, investors are invited to submit questions via the Investor Q&A form located on the Investor Overview section of our website. With that, I will turn the call over to Jason for additional comments.
