Thanks, Nick, and thank you all for joining us today. We achieved excellent results in the second quarter, setting new records across all metrics and surpassing the midpoint of our adjusted EBITDA guidance. Revenue increased 18% year-over-year and contribution ex-TAC increased 16% year-over-year, both in line with our quarterly guidance. This strong growth was fueled by demand for our unique CTV offering, increased adoption of Viant's addressability solutions and wider use of the ViantAI product suite. Adjusted EBITDA increased 18% year-over-year to $11.3 million for the quarter. Operationally, we continue to execute against our strategic priorities. We further advanced our CTV Direct Access premium publisher program through new publisher integrations. We expanded the presence of our industry-leading audience and content addressability solutions, Household ID and IRIS_ID. And we successfully launched the third phase of our ViantAI product suite, AI Measurement and Analysis, designed to revolutionize reporting with on-demand insights. Our innovative solutions are resonating across the marketplace, enabling Viant to actively pursue and secure new business from advertisers with more pronounced ad budgets. More than ever before, we are engaging with major U.S. advertisers and proactively expanding our addressable market beyond the mid-market advertiser. In a moment, Chris will discuss our evolving go-to-market strategy influenced by the ongoing rollout of ViantAI and provide an update on our growing business pipeline with major U.S. advertisers. Before that, I will provide a detailed update on our key strategic priorities: CTV, addressability and ViantAI. CTV was the strongest driver of top line growth in the quarter. We continue to position Viant as the preeminent DSP for CTV advertising. And once again, our results demonstrate that we are doing just that. In the first half of 2025, approximately 45% of total ad spend on our platform was CTV, and approximately half of that spend ran through our direct access premium publishers. Unique to Viant, the Direct Access premium publisher program connects advertisers directly to premium CTV inventory, significantly reducing supply side fees. This means more ad spend goes directly toward working media, increasing impression win rates without the need to raise bid prices, improving return on ad spend for our customers. Notable Direct Access premium publishers include the likes of Disney, Paramount, Peacock, Roku and many, many others. We recently welcomed LG, a major CTV OEM to our Direct Access premium publisher program. This partnership offers our advertisers an efficient supply path to reach LG's 45 million connected devices across the U.S. The integration also incorporates data matching, which further enhances the efficacy of Viant Household ID for audience targeting and measurement. Furthermore, LG has integrated Viant's leading content identifier, IRIS_ID, allowing advertisers to target and measure based on content relevance. This leads me to our expanding leadership position in addressability. Viant Household ID, our patented audience targeting and measurement solution continues to see strong utilization amongst advertisers. Household ID identifies approximately 95% of U.S. households and boasts availability across about 80% of biddable ad inventory, significantly exceeding alternative identifiers and enabling sophisticated audience targeting and measurement at unmatched scale. In the second quarter, ad spend linked to Household ID increased 15% year-over-year as we continue to activate Household ID matches with our premium Direct Access publishers, making their inventory both biddable and addressable. We anticipate continued growth in utilization of our Household ID as data-driven advertisers increasingly prioritize the CTV channel. Our content targeting and measurement solution, IRIS_ID, continues to ramp across publishers. Building on existing momentum, IRIS_ID is now integrated with Wurl, a leading CTV content distributor. Under the AppLovin umbrella, Wurl powers over 3,000 FAST channels across more than 55 streaming services and significantly expands the reach of IRIS_ID. Notably, this partnership marks the first time Wurl's premium FAST supply is available via programmatic real-time bidding within any DSP, a testament to our ability to bring new innovative solutions to market. Since acquiring IRIS.TV in November 2024, the presence of IRIS_ID across all available CTV bid requests has grown substantially, and we expect it will continue to climb as we onboard new publishers. As a reminder, IRIS_ID allows advertisers to target CTV ad inventory at the video level, enabling advertisers the ability to align their brand, product or service with contextually relevant content. In doing so, advertisers have been shown to experience a 5x lift in brand favorability, a 3x lift in ad recall and a 2x lift in brand awareness and consideration versus CTV control groups. As IRIS_ID continues to be integrated amongst publishers, advertisers gain the ability to deploy contextual campaigns at greater scale, which we believe will lead to increased utilization. Finally, I'd like to provide an update on our ViantAI product suite. We have now successfully rolled out 3 phases of our AI product suite with the recent launch of AI Measurement and Analysis in late June. Recall, the rollout of ViantAI consists of 4 total phases, including AI Bidding, AI Planning, AI Measurement and Analysis and AI Decisioning. I'll very briefly touch on all 4. Nearly 2 years after launch, AI Bidding automates approximately 85% of the ad spending on Viant's platform. With AI Bidding, advertisers enable Viant's algorithms to find and buy optimal ad placements across the open Internet, aiming for the lowest cost while meeting their desired KPIs, which often include reach, frequency and targeting specifications. With surging use, contribution ex-TAC generated from AI Bidding has doubled year-over-year. Early in the third quarter, we rolled out our most impactful AI Bidding model yet. While competing DSPs tout 1% tech fees, our latest AI Bidding model delivers up to 46% reductions in media costs. We believe we are just scratching the surface with AI Bidding. And through continuous innovation, we can deliver even greater savings for our clients. Advertisers can only expect to achieve these types of savings from a buy-side-only platform that doesn't own the ad inventory like Google and Amazon. In Q3 2024, we launched AI Planning, which enables advertisers to create enterprise-level campaigns in seconds. As we have continued to build awareness across the marketplace, we have seen major U.S. advertisers express interest. Relative to our existing customer base, these are bigger brands with more pronounced ad budgets. We are engaged with various CPGs, QSRs, retailers and more. They all see how ViantAI can transform their business. And the feedback is consistent. There is simply nothing else in the market like ViantAI. AI Planning streamlines the workload of media planning and execution teams. Users need only provide an advertiser name, budget, time frame and goal and within seconds, an enterprise-level media campaign designed to maximize return on ad spend is fully constructed, inclusive of budget allocation across all digital channels and publishers, audience segmentation, frequency capping, dayparting, CPM pricing and more. With a single click, the media plan is directly exported into the DSP for immediate execution, automating and streamlining tasks traditionally handled by teams of media planners and traders. It's clear to see why agencies and advertisers of all sizes are eager to work with Viant. AI Planning improves workflow, drives operational efficiency and delivers a higher return on ad spend. We are very encouraged by recent momentum and expect to win material ad spend from major U.S. advertisers moving forward. AI Measurement and Analysis launched in late second quarter and revolutionizes reporting with on-demand insights. Historically, campaign performance data has been spread across multiple dashboards, buried in spreadsheets and has required the expertise of specialized data scientists to interpret results and identify actionable insights. AI Measurement and Analysis is the easy button, built to surface actionable insights and optimization opportunities in an instant via a simple, user-friendly, chat-based interface. For agencies and advertisers, AI Measurement and Analysis provides on-demand answers to all campaign performance-related questions and offers optimization recommendations. These features represent a significant improvement to the user experience, and we believe they will further drive our customers to consolidate their ad spend on the Viant DSP. And finally, we expect to launch AI Decisioning in the second half of 2025. We are on the cusp of providing advertisers with a fully autonomous ad solution for deployment across the open Internet. AI Decisioning enables advertisers to grant ViantAI the autonomy to plan, build, execute and optimize ad campaigns in full. ViantAI is dynamic and is designed to proactively react to market conditions, adjusting campaigns as necessary to deliver the best possible outcomes. And in contrast to big tech black box competition, ViantAI is transparent, providing advertisers with unrestricted insight across campaign performance data, including publisher allocation, clearing prices, return on ad spend metrics and more. To summarize, we delivered a strong quarter and made significant progress expanding our product capabilities across our strategic priorities, CTV, addressability and ViantAI. Our commitment to innovation is driving unprecedented engagement with major U.S. advertisers, presenting an opportunity for Viant to take share in a new addressable market. With demand ramping across our platform, we believe we remain well positioned to deliver sustainable long-term growth. Before turning it over to Chris, I would like to take a moment to welcome Brett Wilson to Viant's Board of Directors. Brett is an experienced entrepreneur, executive and investor with almost 30 years of experience in technology, advertising and digital media. He is the former Co-Founder, President and CEO of TubeMogul, an ad tech company he led from inception to IPO to a successful exit. His extensive knowledge in ad tech and AI will be crucial as we continue to innovate and accelerate our growth, and we're thrilled to have him on the board. With that, I will pass it over to Chris.
