Thanks, Tim. And thank you everyone for joining us today. Before I begin, I'd like to remind everyone that consistent with last quarter we have posted supplemental financial slides to our Investor Relations website to accompany today's presentation. As Tim mentioned, we are pleased to report that once again, we exceeded our previously issued guidance across all metrics in Q3 and are again raising our guidance for the full year. We continue to see increased customer adoption of our platform. And believe we are well positioned for a strong Q4 and 2022 as our investments in personnel and technology mature. This afternoon, I will be discussing some of the highlights of our Q3 performance as well as some of the key financial and operational drivers during the quarter. I will also be reviewing our current expectations for Q4 and for the full year 2021. With that, let me discuss some key highlights for the quarter. During the quarter, we began seeing the benefits of our world without cookies software release with customers increasing adoption across multiple channels where cookies or device identifiers do not exist such as Connected TV, mobile, streaming audio and digital out-of-home. Our continued investment in our team and technology also continues to pay dividends as evidenced by our solid increase in the number of active customers for the second quarter in a row. For the quarter, total platform spend increased 28% versus last year. GAAP revenue for the quarter was $50.9 million, an increase of 26% compared to Q3 of 2020. And contribution ex TAC was $34.1 million for the quarter, an increase of 22% on a year-over-year basis. In terms of our previously discussed COVID-impacted customer verticals. We continue to see a solid recovery in Q3 across our retail and travel customer verticals. However, our auto customer vertical continues to be negatively impacted by the ongoing chip shortage. In Q3, we also saw a pullback in spend with some of our CPG customers attributable to supply chain issues. As such, whereas in recent quarters, we've been reporting the impact of COVID across 3 customer verticals, retail, auto and travel. This quarter, we will report the impact from COVID and supply chain-related issues across two customer verticals, auto and CPG. Contribution ex TAC associated with our auto and CPG verticals declined 43% in Q3 as a result of supply chain-related challenges. These 2 customer verticals represented 46% of our total contribution ex TAC last year. And as a result of the declines in Q3 of this year these 2 verticals represented just 21% of our total contribution ex TAC this quarter. In terms of CPG, based on what we are seeing in Q4 thus far, we believe these issues were largely contained within Q3 across a limited number of customers. And we expect stronger performance out of CPG in Q4. Across all other customer verticals outside of CPG and auto, which includes retail, travel, health care and entertainment, among others, we saw a 76% increase in contribution ex TAC during the quarter. These non-impacted verticals represented 54% of total contribution ex TAC last year and now represents 79% of the total. While these supply chain-related challenges impacted our growth during the quarter. The fact that we exceeded our previously issued guidance and are raising our guidance for the full year speaks to the resilience and differentiation that our platform brings to the market. The headwinds created by the supply chain impact of verticals will create an additional tailwind for growth as these issues are resolved in the coming quarters. From a channel perspective, our WWC software release during the quarter drove an increase in omnichannel adoption by our customers as they can now leverage our unique household ID to seamlessly buy and measure their ad spend across digital channels where cookies or device identifiers do not exist. In Q3, we saw broad-based strength across all of these channels. Contribution ex TAC from mobile, streaming audio and digital out-of-home grew 56% in Q3, while CTV grew 28% during the quarter. Growth in mobile during the quarter was partly driven by an influx of dollars coming on to the platform as a result of some of the market dynamics that the social and mobile ecosystems are facing as a result of Apple's recent IDFA changes. Marketers are testing and adopting our people-based approach as an alternative solution to better target and measure in this important channel, which we believe is another important tailwind for our business going forward. In terms of CTV, we did see a slowdown in growth of contribution ex TAC relative to last quarter. This is largely as a result of a change in customer mix during the quarter created by the supply chain issues I previously mentioned. With CPG and auto marketers historically being big CTV buyers, the declines across these 2 important verticals during the quarter certainly muted our CTV growth rates in the quarter. CPG and auto customers represented 51% of CTV-related contribution ex TAC in 2020 and 42% of CTV-related contribution ex TAC in the first half of '21. In Q3, CPG and auto customers only represented 22% of our CTV-related contribution ex TAC. Excluding the impact of CPG and auto, CTV-related contribution ex TAC across all of the customer verticals grew 92% in Q3. Notably, we are already seeing a reacceleration of growth in CTV in Q4 with growth rates accelerating well beyond Q3 levels thus far into the quarter. With growth in CTV ad spend expected to outpace overall programmatic growth in the near term we believe our people-based approach will continue to drive adoption across our platform, thus providing another driver of our growth going forward. On the customer front, the number of active customers and the average contribution ex TAC per active customer saw strong momentum in the quarter. At the end of Q3, we had 305 active customers versus 258 in the prior year period, representing an increase of 47 customers or 18% on a year-over-year basis. Sequentially, the number of active customers increased by 17 compared to the end of Q2, representing our second consecutive quarter of double-digit growth in the number of active customers. We have now added a total of 39 active customers since the end of Q1. The biggest driver of new customer additions in the quarter had to do with our continued success across mid-market agencies, which Chris will discuss further in a moment. Average contribution ex TAC per active customer at the end of Q3 totaled 433,000 versus 404,000 at the end of Q3 last year representing an increase of 7%. As we continue to ramp our sales and technology investment in 2021 and beyond. We expect further momentum around new customer acquisitions and average contribution ex TAC per active customer. Now turning to operating expenses. I will be discussing operating expenses, excluding the impact of stock-based comp and also excluding traffic acquisition costs, which are included in platform operations but are deducted from revenue to arrive at contribution ex TAC. Total operating expenses, excluding stock-based compensation and traffic acquisition costs totaled $30.5 million in the quarter, an increase of 51% or $10.2 million versus the prior year period. The year-over-year increase in operating expenses is primarily attributable to the planned investments we are making across the organization with a particular emphasis on ramping our sales and technology infrastructure. Given the significant market opportunity in front of us, we believe these investments will drive growth in the quarters ahead. Adjusted EBITDA for the quarter was $6.5 million, and our adjusted EBITDA margin as a percentage of contribution ex TAC was 19% in the quarter. While 2021 is certainly an investment year in terms of scaling the business our mid- to long-term targeted adjusted EBITDA margin remains at 35%. For the quarter, non-GAAP net income, which excludes stock-based compensation, totaled $3.1 million and non-GAAP earnings per diluted share of Class A common stock totaled $0.04 for the quarter. From a cash flow perspective, we generated $6.5 million of net cash from operating activities in Q3 and ended the quarter with $243 million in cash. We believe that our growth profile and healthy balance sheet position us extremely well to take advantage of the rapidly growing market opportunity in front of us. In terms of share count, we had an average of 13.5 million Class A common shares outstanding during the quarter and we expect the Class A common share count to increase to approximately 13.8 million in Q4, primarily as a result of RSUs vesting. And finally, I'll now turn to our outlook for the remainder of 2021. As Tim discussed, we feel great about our strong positioning in the market, and we are in very early stages of capitalizing on the market opportunity for programmatic advertising. Given the increasing momentum we are seeing across the business, despite some macro challenges, we are once again increasing our guidance for the full year. For the fourth quarter of 2021 we now expect GAAP revenue in the range of $71 million to $74 million, which represents year-over-year growth of approximately 26% to 31%. Contribution ex TAC in the range of $47.5 million to $50 million, which represents year-over-year growth of approximately 21% to 28%. And adjusted EBITDA in the range of $13.5 million to $14.5 million or a margin as a percentage of contribution ex TAC of 28% to 29%. And for the full year, we now expect GAAP revenue in the range of $212.4 million to $215.4 million, which represents year-over-year growth of approximately 29% to 30% and contribution ex TAC in the range of $140.5 million to $143 million, which represents year-over-year growth of approximately 27% to 29% and adjusted EBITDA in the range of $33.2 million to $34.2 million or a margin as a percentage of contribution ex TAC of 24%. With that, I will now turn the call over to Chris.
