Our adjusted EBITDA was positive $20.3 million. The world of AI is very exciting, but it contains an unsustainable imbalance, and all of you know what it is. There's a monstrous amount of investment in AI. The largest American tech firms spent nearly a quarter of a trillion dollars of CapEx last year without a proportional return. AI does not generate enough revenue because AI does not generate enough value. And this is where Appian Corporation can help. Appian Corporation creates real value with AI, like putting it where it can do the most good. While other firms bring work to AI, we bring AI to work. I mean, we go where work happens, and that's where we deploy AI. We equip AI to make an impact directly in the places where the heaviest and most valuable work already occurs. Work happens inside of a process. A process is a high-volume flow of tasks handled individually and procedurally inside a corporation. These tasks are carefully orchestrated to serve an important goal. Process is how an insurer manages claims, and a bank validates money. It's how the government operates procurement cycles and pharma companies run clinical trials. Process is how organizations spend their money, serve their customers, comply with regulation, and build their reputations. Appian Corporation is called The Process Company, and we do a lot of processes. Appian Corporation runs 10 to 20 billion transactions per day on AWS alone. A lot of those transactions will run better when we apply AI. We used to staff our processes with digital workers like RPA and business rules. Now that we have AI, I believe that the value of process automation technology has roughly doubled. It will take years for that value to reach our accessible market, but it's real. And the value of AI can also double its use in a process. That is a bold statement, but if it sounds like an exaggeration that the value of AI could double when used in a process, then hear me out as I make the case for AI process synergy. Here are six ways AI is better when deployed in an Appian Corporation process, starting on slide five in the earnings deck. First, it's easy to instantiate AI within an Appian Corporation process. To launch an AI agent in any node of a process model takes only a few clicks. Customers can use AI to make suggestions, generate content, parse documents, or take action. We are agnostic about the AI model. Customers can use ours, usually Claude, or bring their own. We are making it easier to access AI, and if Deepseek commoditizes AI or makes it cheaper, we and our customers stand only to gain. Second, on slide six, our process gives AI structure. For AI to make value in high-volume workflows, it must have a structured process. Process gives AI a job within a coordinated effort working toward an important goal. AI gets a team of coworkers, an inbox and an outbox, an escalation path, exception handling, and human oversight. I want to emphasize this human to AI coordination. Many processes that can benefit from AI require humans as well as overseers, exception handlers, or final results checkers. For example, one of our customers, an international health technology company, uses AI in a process to allocate human attention to incoming work. They sell medical devices and supplies to healthcare providers, and they are working with us to automate order fulfillment. A third of their orders are submitted through email, and those emails will be processed by Appian Corporation AI agents whose job is to parse, appraise, and route correspondence to the right actor within the organization. Many of these requests require a human response, so the AI will frequently assign the next stage of the work to a person. The third reason why Appian Corporation Process is good for AI is data. AI needs data, and different implementations require different provisioning strategies. It's not always enough to make a heap of data and train your AI model once. Sometimes you need data from disparate systems, or you need fresh data in real-time from remote sources of record. Or you may wish to retrain periodically on a freshly assembled dataset. If you are privacy-minded, you may wish not to train at all but instead want data provided in the month. Our process platform sends AI the right data at the right time. The fourth reason AI is better in a process is that we give agents what they need to be successful. Agents seek data then act. First, they need to query and learn, and for that, our data fabric is ideal. Then they need to launch powerful actions. These actions should be far-reaching and coordinated, predictable, comprehensive, and fail-safe. In short, they should be processes. Only a process provides the power and the guardrails agents need when taking action. Appian Corporation had agents before the term was invented; we called them skills. But we did it the right way, with more structure and stronger actions. Those who let agentic AI improvise without guardrails are making a mistake. Here's an example from a top US mortgage lender that became a new Appian Corporation customer earlier this year. It uses Appian Corporation to automate audit processes for over 10,000 loans annually. Our AI agents analyze hundreds of different forms and cross-validate data with the company's origination system. With 98% accuracy, the agents flagged discrepancies so human auditors can review and correct the data before publishing loans to the secondary market. The company now runs this previously manual process more than four times faster using Appian Corporation. The fifth reason why AI is better inside a process platform is visibility. Everything that happens in a process platform like ours is tracked. Every node, every action, every delay, every read and write, every outcome. AI is typically a black box, but to understand it better, put it in a process. Then you can track what impact it has, what it does well or poorly, where it makes mistakes, where are its blind spots. And whatever you learn from this exercise, you can apply in the process platform from rerouting certain jobs to gathering a new training dataset. The data-rich environment of a process is great for validating your investment in AI and justifying your next project. And if you work in a highly regulated industry, this visibility might be a prerequisite to making any use of AI at all. Finally, my sixth reason Appian Corporation makes AI scalable. A process platform isn't just a workflow; it's an application environment. Appian Corporation gives AI up-to-date security certifications, an interface usable on any mobile device, hot failover, DDIL capability, and auto-scale for usage spikes. That's why top global organizations run their most critical and complex processes on Appian Corporation. Our customers include over half the top life sciences asset managers and insurance companies, and every US government cabinet-level agency. Speaking of the federal government, there's a lot of change in that market right now. We are cautiously optimistic about the opportunity these changes may create. For 25 years, Appian Corporation has been a vehicle for efficiency and modernization in the US government. Our Army Knowledge Online deployment was, in its day, the world's largest internet. We rescued a portion of the Affordable Care Act from a faulty technology implementation. We've become an acquisition management standard for civilian defense and state agencies. We advance efficiency from optimizing how money is spent to maximizing the efficacy of each action. For example, a US military branch and longtime customer expanded its use of Appian Corporation into a new mission area this quarter. This group runs core operations like logistics, finances, and supply chain management on a series of legacy enterprise resource planning systems. The organization will consolidate these systems into a single Appian Corporation view for hundreds of thousands of users and expects to save tens of millions of dollars annually. Appian Corporation continues to upsell our existing customer base by launching new products and identifying new use cases. Two-thirds of our customers at the beginning of 2024 purchased more software during the year. We launched a tiered pricing structure last February to monetize advanced functionality like AI. Almost half of our new customers bought in above the base tier. Going forward, we hope to increase that share and to convert more existing customers. A leading US insurance provider is one of our existing customers that upgraded its licenses in Q4. The group has been using Appian Corporation for more than a decade to manage risk and compliance and automate processes across its enterprise. The customer used Appian Corporation to expand its reinsurance business practice and generate an additional $2 billion in revenue annually. This quarter, the customer purchased a seven-figure upgrade and plans to widely deploy new capabilities like Appian Corporation AI agents. My last customer example is a medical transportation emergency response company. I mentioned them in Q2 when they became a new Appian Corporation customer. The group has since reduced its appeal disputes processing times by 88% using Appian Corporation. Now the firm signed a seven-figure software deal in Q4 to integrate siloed systems and orchestrate its full claims lifecycle. And now I'll conclude my prepared remarks. This year, Appian Corporation's focus is on the basics. Our core principles are market identity, our financial goals, our strategic priorities, and our operational rigor. We believe we have an opportunity for growth, being a leader in a growing and changing market. Growth remains our priority. If you'd like to learn more about Appian Corporation, the best place to go is our annual conference, Appian World. This year, we're meeting in Denver from April 27 to 30. You're all invited, and I hope to see you there. Now let's talk about the financials with Mark. Welcome back, Mark.
