Thank you, Jonathan. Welcome, everyone, to our 2024 first quarter call. Revenue and adjusted EBITDA for the first quarter exceeded our prior expectations. Revenue grew 8% to $114.5 million, ahead of our prior outlook of $111 million to $113 million. Adjusted EBITDA was $33.1 million at a 29% adjusted EBITDA margin. As we moved through the first quarter, we benefited from increased advertiser demand for our industry-leading products, particularly in social media. Our first quarter performance includes the previously discussed factors within measurement and optimization that we anticipated. We expect favorable demand trends for our products in the second quarter, and we are increasing our full year outlook. On today's call, I'll address the importance of data integrity and our trusted AI-backed technology, the strong momentum in social media across platforms, our robust product pipeline in both measurement and optimization and several high-growth opportunities that we continue to prioritize. Marketers trust IAS to protect, measure, inform and optimize their brand campaigns. Their trust is based on the accuracy and reliability of our data. Data integrity is critical and inherent in all the reporting and insights we provide in every aspect of our business. Data science is at the heart of our business strategy. Our AI systems enable models that deliver classifications and analytics at greater speed that are scalable with extremely high precision. This in turn helps deliver the most actionable data to our clients. In a recent IAS study, our AI technology delivered up to 74% more accurate brand suitability measurement across social media platforms when compared to other provider solutions. While IAS is focused on harnessing the power of AI, we are committed to doing it responsibly. We are investing in explainable AI, which ensures that our customers can trust our models. The accuracy, reliability and integrity of our data is anchored in our AI innovation as well as in our critical role as an independent third-party provider. This allows us to maximize the value we offer, all while maintaining and growing the trust customers have in IAS. A few weeks ago, I presented a TikTok Second Annual Beyond Brand Safety Summit, along with TikTok's Head of Global ad tech partnerships and brand innovation product lead. TikTok selected IAS is the only third-party measurement partner to speak at the event highlighting the essential role IAS play in supporting TikTok advertisers. Our leading partnership with TikTok as well as our recently announced exclusive first-to-market partnerships with X and Snap demonstrate the trust's major platforms placed in IAS, which fuels our innovation. At IAS, we lead with customer obsession, putting the customer first and ensuring we're at the forefront of innovation has resulted in a highly sticky customer base with an average tenure of 8-plus years for our top 100 marketers. We have increased wallet share with our large customers as a result of organic volume growth, upsell cross-sell of new products, expansion into new global markets and channels as well as land to expand within existing customer brand portfolios. Since 2019, we've seen a 55% increase in average annual spend in year 2 of new contracts based on our advertiser customer data. We're pleased to have secured several recent wins and renewal expansions across industry verticals, including CPG, telecommunications, automotive and financial services. We have also proven our ability to grow with our customers as they shift advertising budgets to capture the explosive growth of social media, including short-form video. Social media measurement revenue represented 21% of total revenue and grew 40% in the first quarter due to the rapid adoption of our total media quality TMP product suite. IAS is leading in social media with integrations across the major social platforms, including Meta, YouTube and TikTok. IAS has also established industry-first partnerships with X and Snap further validating the superiority of our social media offerings. With Meta, we've achieved strong adoption of our AI-driven TMQ brand safety and suitability measurement product across Facebook and Instagram Feed and reels total volume of impressions on Meta increased more than 50% in the first quarter since brand safety and suitability measurement launched on February 5. We're delighted to announce that we've expanded availability of our brand safety and suitability measurement on Meta to include 21 new languages for a total of 28 supported languages. In April, we've also expanded to include our GARM-Aligned misinformation measurement to meet growing advertiser demand ahead of the upcoming U.S. elections. With TikTok, we expanded our global industry-leading brand safety and suitability measurement to 12 GARM categories and 15 vertical sensitivity category exclusion segments in April. We added 11 countries for total coverage of over 60 countries. We also expanded our measurement ease of activation with automated suitability profiles and enhanced reporting capabilities, validating that our customers' adds are appearing in brand suitable environments. With YouTube, we earned MRC accreditation in March for our integrated third-party calculation and reporting of YouTube video viewability for desktop and mobile, including web and app using Google's ads DataHub for measurement partners. In February, IAS launched its exclusive prebid product with X, providing the opportunity for U.S. advertisers to opt in to activate prebid IAS optimization for X and the vertical video product. IAS classifieds vertical video ad agencies for brand safety and suitability aligns to the GARM framework giving advertisers maximum control over where their ads appear on the X vertical video feeds. Our relationship with X is based on trust and transparency with the foundation built on the accuracy of our data. In March, IAS announced a first-to-market partnership on Snap to provide AI-driven brand safety and suitability measurement for advertisers. By integrating our TMQ product suite, advertisers on Snap will have access to increase transparency across their Snaptrack campaigns. We're currently in development and expect to go live later this year. This announcement expands our partnership with Snap, which dates back to 2018 in which IAS launched viewability and IBT measurement. We are prioritizing offerings in measurement and optimization that drive superior results and ROI for our customers and an increasingly cookie-free world we are expanding the reach of our quality Sync product to new DSPs, which simplifies activation for our prebid optimization products, QSP revenue more than tripled year-over-year in the first quarter. In the first quarter, we increased adoption of our total visibility product. Total visibility enables customers to connect performance metrics such as conversions and sales lift, supply path and cost of media to IAS' media quality metrics. In April, IAS expand our MFA AI-driven solution to GA after an extensive beta that spanned over 100 campaigns. Our MFA solution is the first to measure and optimize against both MFA and ad clutter sites to drive maximum efficacy across the programmatic buying process. Our quality attention solution went live in early January and has experienced significant growth in active customers since launch. Our differentiated approach unifies media quality and eye tracking with machine learning to deliver proven results for advertisers. Higher attention drives better sales performance in a recent study in partnership with NC Solutions on behalf of the major CPG client, we found that impressions with higher retention scores drove an increase of 157% in incremental sales versus impressions with lower attention scores. Ahead of this year's U.S. elections, IAS is helping protect brands by enabling them to identify and avoid misinformation using a combination of AI-backed technology and human detection. IAS has been combating misinformation on the open web since 2021 in partnership with the Global Disinformation Index, or GDI and aligned with GARM standards. We've significantly enhanced our misinformation offering to include TMQ and leading social platforms. During the quarter, we realized double-digit revenue growth with our mid-tier clients. We have established new partnerships with mid-tier DSPs, including 2 in the important pharmaceutical sector. We also signed 5 mid-tier agencies as their preferred or exclusive partners. Lastly, we continue to invest in high-growth opportunities, including CTV, retail media and gaming. During the quarter, Publica by IAS partnered with CNN and Turner Sports in EMEA. Both publisher partners used Publica by IAS' unified ad [oxen's] solution to increase fields and guarantee the best viewing experience for users. We are delighted to announce that Cam Miile will be joining IAS as Chief Revenue Officer at Publica. With over 12 years in sales leadership roles at FreeWheel and OpenX, Cam possesses deep knowledge of the CTV and publisher landscape. We look forward to welcoming Cam to the team. In April, IS received accreditation for filtration of sophisticated invalid traffic and CTV environments as applied to video impressions, viewable impressions and viewability related metrics. Our latest MRC accreditations demonstrate our continuing commitment to transparency into the MRC process. In the last 12 months, we've achieved 10 third-party certification, accreditations, including 4 from the MRC. In April, IAS was one of the first companies to receive Trust Ark's trustee responsible AI certification, demonstrating our commitment and alignment with the highest standards of AI governance. The certification validates our practices for the development and deployment of AI systems are secure, fair and transparent. In Retail Media, IAS is a leader in independent verification with coverage for viewability, IBT and brand safety with the top retail media networks. In the first quarter, volume from Retail Media Networks grew 88%. Last week, IAS announced the first-to-market integration with roadblocks to provide 3D in-game viewability and invalid traffic measurement in the immersive environment. Advertisers can access best-in-class third-party measurement to verify that their immersive, in-game advertisements on roadblocks are driving engagement with real users. To conclude, first quarter results exceeded our prior outlook, and we expect accelerated growth in the second quarter. As previously discussed, we expect the measurement contract renewals to be net revenue positive in 2024. In addition, new products and recent customer wins, along with other contributing factors reinforce our confidence in our increased full year outlook. And with that, I'll turn the call over to Tania to review the financials, and then we'll take your questions.
