Thanks, Brian, and thank you, everyone, for joining us today. In the third quarter of 2025, Appian's cloud subscriptions revenue grew 21% to $113.6 million. Subscriptions revenue grew 20% to $147.2 million. Total revenue grew 21% to $187.0 million. Adjusted EBITDA was $32.2 million. This quarter, Appian made big strides on our 2 efficiency metrics. Our go-to-market productivity ratio rose to 3.5. This is the ninth consecutive quarterly increase, see Slide 4. We keep getting more from our sales and marketing dollars, an intended outcome of our strategy over the last few years. In Q3, our weighted Rule of 40 score was 39, up from 31 last quarter. As a reminder, Appian's weighted Rule of 40 puts double weight on cloud subscriptions revenue growth compared to adjusted EBITDA margin. The AI revolution took an important turn this summer. Businesses started to realize that AI isn't as valuable unless it's connected to real work and that you need a process or a workflow to make that connection. The most important factor was probably the July MIT report that told us that 95% of AI implementations were getting no return. As MIT wrote, "The standout performers are those embedding themselves inside workflows. And people are getting the message. Looking at Google Search trends, the term AI moderately increased over the past 12 months, but the combination of AI in terms like process and workflow spiked this summer. News outlets like Forbes and Fast Company are publishing headlines like why AI isn't delivering the value you expected and good AI innovation means focusing on workflow, not cutting jobs. This trend also matches my personal experience and customer conversations. I see corporations quickly losing interest in stand-alone AI deployments and favoring the use of AI in the context of a process. This new realization is not a surprise to Appian nor to you if you've been listening to our calls for the last couple of years. We have said consistently that AI forms one corner of an essential trio of technologies and AI triangle, if you like, in which AI is dependent upon each of the others. I've never had trouble convincing people that AI is only as good as the data you give it. It's obvious that AI agents cannot research cases, reach conclusions, solve problems or get smarter without 360-degree access to data. Our data fabric remains the gold standard in providing data to AI without having to migrate it. Only recently have people started naturally agreeing with my second assertion that AI is only as good as the work you give it. AI will add more value if it works on the more valuable tasks. And the most valuable tasks involve many workers and many steps and are coordinated in a process. As such, process is an essential tool in connecting AI to meaningful work. With industry-leading process technology, we offer the missing link between AI and today's most important jobs. When you combine AI, data and process, you can address bigger work and create bigger value. We call this serious AI. It's an exciting crossroads at which to do business, and we are not new here. Appian has orchestrated enterprise business processes for over 2 decades. We are recognized by industry analysts as a leader in process orchestration, business workflow automation, digital process automation and most recently, the inaugural Gartner Magic Quadrant for business orchestration and automation technologies. I'd like to share with you a few examples of serious AI. First, a global pharmaceutical company and 7-figure cloud ARR customer manages its global anti-bribery and corruption practices on our platform. Appian already automates the company's highly regulated process for approving interactions with external health care practitioners and vendors. However, cycle times are slowed. By the many human reviews the customer built into its process. In Q3, it purchased a 7-figure software deal to deploy Appian AI. Now our agents will ingest hundreds of thousands of requests, validate compliance and recommend a status. This major pharma company expects to speed up the critical process by 80% with Appian. Next, a U.S. military command became a new Appian customer in Q3 and will use our platform to automate end-to-end warehouse fulfillment processes. Upon receipt of goods, Appian AI agents will extract shipment data and open a case on our platform, so warehouse workers can validate the package and approve it for distribution. Meanwhile, back-office staff will track fulfillment status and coordinate logistics. Before Appian, the organization had prolonged distributions because its processes were disjointed and manual. Now the combination of Appian AI and data fabric will reduce processing time from weeks to minutes. Customers see strong quantifiable value using Appian AI in their core processes. Organizations have reported 36% reduction in invoice processing times, 83% faster patient intake, 3x faster audit processing and 95% automation of the order management process, good ROI, and they're willing to pay for it. Today, over 1/4 of our customer base pays for Appian AI. Of those paying AI users, nearly half use our AI-powered intelligent document processing or IDP. This is a really powerful offering. Appian IDP agents can ingest a wide range of complex documents from unstructured e-mails to medical reports and insurance claims. Our agents read documents with 95% to 99% accuracy, which is significantly better than the 60% accuracy rate of traditional document recognition technology. For example, one international insurer uses Appian IDP to optimize its underwriting processes and save millions of dollars a year. These strengths are why Gartner ranked Appian #1 in automated processing use cases for IDP in their 2025 Critical Capabilities report. Appian IDP agents take autonomous action. They explore data from across the enterprise to inform their decision-making on each new document. Once they contextualize and understand the incoming document, they launch actions in the form of Appian processes. For example, a global insurer purchased a 7-figure cloud software deal to automate its underwriting process and became a new Appian customer in Q3. Appian's AI agents will ingest e-mails and policy forms, open cases and automatically decline ineligible submissions. The insurer expects to improve its auto declination rate by 20% and grow its written premiums practice to $10 billion within the next 3 years using Appian. Early in 2024, we launched an AI product for improving government procurement. You may remember it, it's called ProcureSight. We collected a ton of publicly available government procurement data sets and connected that to our process technology so our users could publish smarter RFPs. 96 U.S. government agencies and sub-agencies have adopted it so far. Now customers are purchasing advanced levels of the offering to embed the AI into their procurement workflows and connect it to both public and private data sets. For example, a U.S. Air and Space agency already automated its contract writing process with Appian technology. This quarter, it signed a 7-figure deal to automate additional phases of its procurement process with more prebuilt Appian solutions featuring AI. I usually talk about releases after they happen, but we have a big one in 10 days, and I'd like to share it with you now. We're launching a major feature called Agent Studio that's going to enable the most powerful agents we've ever made with easy code-free natural language configuration. This is a highly anticipated feature judging by the oversubscription on the beta program and the widespread pre-GA deployment. The technology is poised for broad usage on release to triage customer complaints, initiate credit checks and loan applications and conduct background reviews. Most of you are familiar with Appian's multiyear quest to focus on the top end of our market. Appian has a particular advantage upmarket, and it shows in the data. Appian suits the needs of the executive buyer and the large enterprise and the mission-critical use case. Compared to last Q3, Appian booked over 50% more new 7-figure software deals. We're pleased with our federal sector performance this fiscal year, which grew faster than our overall business. Our upmarket strategy will continue to drive momentum in the U.S. public sector once the government reopens. I'll share 2 big wins from Q3. First, a major restaurant franchise operator plans to open 1,000 new locations next year. In Q3, it purchased Appian Cloud licenses and became a new customer after the Chief Technology Officer of a peer organization endorsed our platform. The customer's restaurant opening process used to take several months because the franchise and third parties worked across siloed systems. Now it will use Appian to unify the enterprise and create a comprehensive workflow to reduce opening time lines by 40%. Finally, a U.S. military branch and existing Appian customer is under executive mandate to modernize core systems and improve operational agility within a fixed time period. This quarter, it purchased Appian software to decommission and flexible systems supporting its complex incident management process. Now Appian will provide a consolidated and more feature-rich application to manage hundreds of thousands of cases annually. Appian's serious AI offering and upmarket strategy continue to drive our growth while expanding margins. I think you can see in the fact that 25% of our customers now pay for AI and in our 50% increase in 7-figure deals. and in our 9 quarters of rising go-to-market efficiency and in our adjusted EBITDA margin of 17% the power and timeliness of our business model. With that, I'll hand the call to Serge.
