Thank you, operator. Good afternoon, and thank you for joining us today to review Appian's third-quarter financial results. With me on the call today are Matt Calkins, chairman and chief executive officer; and Mark Lynch, chief financial officer. After prepared remarks, we will open up the call to a question-and-answer session. During this call, we may make statements related to our business that are forward-looking statements under federal securities laws and are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, including statements related to our financial results, trends and guidance for the fourth quarter, and full year 2020, the impact of COVID-19 on our business and on the global economy, the benefits of our platform, industry, and market trends, our go-to-market and growth strategy, our market opportunity and ability to expand our leadership position, our ability to maintain and upsell existing customers and our ability to acquire new customers. The words anticipate, continue, estimate, expect, intend, will and similar expressions are intended to identify forward-looking statements or similar indications of future expectations. These statements reflect our views only as of today and should not be reflected upon as representing our views as of any subsequent date. These statements are subject to a variety of risks and uncertainties that could cause actual results to differ materially from expectations. For a discussion of the material risks and other important factors that could affect our actual results, please refer to those contained in our Q3 2020 10-Q filing, our 2019 10-K filing, and our other periodic filings with the SEC. These documents and the earnings call presentation are available in the investors section of our website at www.appian.com. Additionally, non-GAAP financial measures will be discussed on this conference call. Please refer to the tables in our earnings release and the investor relations portion of our website for a reconciliation of these measures to their most directly comparable GAAP financial measures. With that, I'd like to turn the call over to our CEO Matt Calkins. Matt?
