Thanks, Jonathan, and welcome everyone to our 2023 third quarter call. We reported strong results that exceeded our prior expectations. Revenue increased 19% to $120.3 million, and adjusted EBITDA reached $40.6 million at 34% margin. We are raising our financial outlook for the full year to reflect our positive third quarter performance and business momentum in the fourth quarter. Tania will provide a detailed review of our financial results and increased outlook for the full year. Let me start by highlighting some key wins and expansions that reinforce the value of our AI-backed products, platform integrations, superior service, and geographic reach. BMW named IAS as its global verification partner. BMW selected IAS for our technology, innovation with products like Total Media Quality or TMQ, vertical expertise in the auto sector, extensive international footprint, and high-quality service. We are delighted that Ferrero, a global sweet-packaged food company has named IAS as its exclusive global measurement and optimization provider. We secured a major renewal and expansion of our partnership with Mars, the home of iconic brands including M&M, Snickers, Kind and Pedigree. This multiyear exclusive agreement includes IAS's leading market measurement and optimization offerings with annual minimum impression commitments. The renewal also expands our relationship with Mars to new markets including Mexico, Brazil, Germany and the APAC region. During the third quarter, we generated a 41% year-over-year increase in social media revenue, surpassing 33% social media growth in the second quarter. The accelerated growth in social media reflects the investments we're making in our technology and integrations with the major social platforms. Our TMQ product identifies higher-quality media at a 3x rate, which leads to higher returns on advertising spend for marketers. As TMQ is AI-backed, the data becomes more accurate and adds greater value over time. We frame the social media opportunity for IAS in terms of big building blocks which are the live feeds, and the medium building blocks of short-form video. Let me update you on the latest initiatives underway. Since expanding inventory coverage of our Total Media Quality for YouTube product suite, impression growth and active accounts have doubled in September from July. We've seen strong customer adoption of TMQ in YouTube from clients including Dyson, Volvo and Kimberly-Clark. Advertisers using our TMQ products on YouTube now have access to a suitability dashboard that allows them to analyze brand suitability trends and create a custom suitability profile. During the quarter, we expanded our brand safety YouTube product suite capabilities to Google Video Partners or GBP. IAS is now providing viewability and invalid traffic, or IVT measurement, for YouTube shorts inventory and offers brand safety, suitability, viewability, and IVT measurement across GBP. In addition, we enhanced our integration with Google Campaign Manager 360. Marketers now have the ability to wrap tags, create and launch campaigns with ease. This enhancement ensures advertiser data is automatically populated in IAS Signal, our UI dashboard, and creates greater efficiencies and reduced campaign creation time. We continue to drive customer adoption of our TMQ brand safety and suitability measurement product on TikTok. TMQ is now available to advertisers in 50 markets, up from 30 at the end of second quarter and ahead of our expectation of 40 markets by year-end. Active measurement campaigns on TikTok have more than doubled year-to-date, and impressions have quadrupled. In August, IAS announced an exclusive first-to-market partnership with X to provide pre-bid brand safety and suitability for video across the social platform. We are currently in beta testing, expect to move quickly to launch in the coming weeks, with a host of blue-chip clients. IAS was selected by X based on the sophistication of our TMQ product. With this expansion, IAS leads the industry in providing end-to-end support for marketers on X with a full array of solutions from measurement to optimization. IAS plans to offer brand suitability verification on Meta for both Facebook and Instagram Feed and Reels. We remain on track to begin client testing in Q4 of this year. Turning to optimization, we are prioritizing ease of activation and transparency, which are particularly important for mid-tier performance-based marketers. We are driving product adoption and streamlining customer activation with a single point of integration. Our differentiated total visibility product enables marketers to optimize campaign spend with greater insights into the quality, supply path and cost of programmatic ads and now with an overlay of marketing outcomes. We've expanded our total visibility offering with our new performance dashboard, which allows marketers to analyze metrics such as success rate over time and cost per action alongside financial and media quality insights. We are also increasing the number of contextual segments, which allows for higher avoidance in targeting customization. Lastly, we are expanding our reach via increased DSP coverage. We are excited to announce that we have enhanced our integration with Amazon Ads to include our context control pre-bid segments. In addition to our standard pre-bid segments within Amazon CSP, customers can now easily discover and avoid unsuitable content and reach contextually relevant content. In Retail Media, IAS is a leader in independent verification with coverage for viewability, fraud and brand safety with the top retail media networks. Year-to-date revenue from Retail Media Networks has grown nearly 150%. We are delighted to partner with Instacart and bring a new level of transparency to Instacart Ads, the company's advertising products and solutions. IAS will provide viewability and IVT measurement on Instacart Ads, which reaches more than 5,500 CPG brands. At Advertising Week in New York City, I hosted a panel that included Tim Castelli, VP, Global Advertising Sales of Instacart. Tim spoke to Instacart's ability to see across the grocery sales ecosystem and to provide actionable data for marketers. We look forward to helping Instacart optimize the Instacart Ads experience for our brand partners. We launched our previously announced first-to-market partnership with Criteo's Commerce Media Platform in September. IAS's partnership with Criteo allows brands and agencies to measure viewability and IVT on a retailer's site across any on-site ad format and in Criteo's network of 210 retail partners. Marketers can be assured their media buys are driving engagement and validating real users. We also launched 8 pre-bid brand safety content categories to allow marketers the ability to optimize their programmatic buying in Criteo's Commerce Max DSP. We've discussed how we are harnessing AI to accelerate the rollout of new markets and advanced capabilities for products such as context control and TMQ. In addition, our product development is fueled by AI, which is a major point of differentiation for IAS and a gamechanger for our customers. AI is a critical component of the new products we're launching in emerging areas, including attention and made for advertising or MFA. Our quality attention measurement product helps advertisers assess campaign performance and unlock superior results. We launched a quality attention beta in August, which generated a high level of interest from advertisers. Over 1.5 billion impressions have already been measured using multivariable models that identify which signals are most relevant to optimize the insights being delivered. In our early beta analysis, we found that higher retention can lead to a nearly 3x lift in success rates and 98% better cost efficiency. We launched the second phase of the measurement beta last week, which includes Lumen's eye-tracking technology. In October, IAS announced its new MFA site detection and voidance solution to align with our customers' media strategies related to this type of content. Leveraging AI and ML, IAS technology aims to improve transparency into advertiser campaign quality, identify where spend is allocated and inform optimizations to minimize waste. According to the ANA's programmatic media supply chain transparency study from June, 21% of all advertisement impressions measured were served on MFA sites. The IAS MFA product is available now as a beta measurement offering with general availability expected in early 2024. In our CTV publisher business, Publica is integrating with TV OEMs, which serve as the entry point into the CTV ecosystem and the live TV experience. OEMs often build their own proprietary advertising businesses and provide their ad-serving technology through growing number of streaming services. During the quarter, Vizio selected Publica to help operate its global CTV advertising business. We look forward to expanding our partnership with Vizio and our previously announced exclusive renewal with Samsung in addition to exploring new OEM opportunities. Publica recently announced a direct integration with Yahoo! Backstage. Via the server, server connection publishers using the Publica ad platform can now access ad budgets from the Yahoo! DSP directly within the Publica unified auction. During the third quarter, we earned our first certification from TrustArc, which conducts annual privacy-focused third-party attestations. The TRUSTe Enterprise Privacy seal certifies that IAS' data privacy policies and practices align with the standards set by the leaders in governance and compliance. To conclude, I am proud of the team for delivering a strong quarter, and we are excited about our positive outlook for the fourth quarter. We are executing against our product roadmap with highly differentiated technology and fast-growing channels, including short-form video. As we begin our planning process for 2024, we intend to prioritize investment in innovation that leverages AI to bring the most advanced products to our customers. And with that, I'll turn the call over to Tania to review the financials.
