Thanks, Chris, and thank you, everyone, for joining us today. Before I begin, I'd like to remind everyone that we have posted a presentation to our Investor Relations website with supplemental financial information to accompany today's presentation. As Tim mentioned, we are very pleased with the market share gains we achieved in Q2. Advertiser spend across our platform increased 32% over the prior year period and 15% over the prior quarter, despite a deceleration in spend that we saw in the last month of the quarter, as some of our customers adjusted their spending levels due to the challenging adverse macroeconomic environment. We continue to be pleased with increased adoption of our software as evidenced by the growth in our active customer base and average spend per active customer, with both increasing year-over-year and quarter-over-quarter. Our growth in advertiser spend has been driven by our long-term strategy of new and existing customers expanding their usage of our platform through our percent of spend pricing option, which we expect to continue moving forward. We believe that the lifetime value of a customer using our percent of spend pricing option is significantly greater than that of a fixed price customer as percent of spend customers typically ramp spend over time as they consolidate their advertising budgets on our platform. Percent of spend customers have also have higher retention rates as compared to fixed-price customers. In Q2, customers using our percent of spend pricing options spent, on average, approximately 3x that of customers using our fixed-price pricing option. Increasing customer adoption of our percent of spend pricing option has always been our goal because we believe it creates a deeper relationship with our customers and provides for more consistent, predictable, long-term value creation. We are pleased to see this adoption occurring faster than we had expected. As a reminder, revenue from our percent of spend pricing option is recorded after deducting traffic acquisition costs, or TAC, whereas fixed price revenue is recorded before deducting TAC. Therefore, as the percent of spend pricing option continues to make up a larger part of our advertiser spend mix relative to the prior year period, we will have a corresponding drag on our revenue and contribution ex-TAC growth rates. While the impact of this mix shift has negatively impacted revenue and contribution ex-TAC growth rates in '22 relative to advertiser spend growth rates, we expect this to significantly improve beginning in 2023 as such growth rates begin to converge as the impact of the mix shift becomes less significant over time. This afternoon, I will be discussing some of the highlights of our Q2 performance, the key financial and operational drivers during the quarter, and our current expectations for Q3. In terms of top line metrics for the second quarter, as I said, advertisers spend across our platform increased 32% over the prior year period and 15% over the prior quarter. On a year-to-date basis through June 30th, advertiser spend has increased 37% from the prior year period. In the second quarter, revenue was $51.2 million, an increase of 2% over the prior year period and 20% over the prior quarter. And contribution ex-TAC was $31.7 million, a decrease of 1% over the prior year period and an increase of 15% over the prior quarter. Growth in advertiser spend on our platform continues to outpace the overall growth of the U.S. programmatic market. Again, this is being driven by increased adoption and accelerating growth across our percent of spend pricing option. From an industry vertical perspective, during the quarter, we saw broad-based strength across all key customer verticals outside of automotive and CPG, which continued to be negatively impacted by pandemic-induced supply chain issues and other adverse macroeconomic developments. Advertiser spend across all customer verticals, excluding automotive and CPG, increased 51% in Q2 versus the prior year period. Spend from our automotive and CPG customers, although down 13% on a year-over-year basis for the quarter, did show some improvement during the quarter, increasing 13% from Q1 levels and 3% from Q4 of last year. Spend across our largest customer vertical, retail, grew an impressive 84% in Q2 versus the prior year period. During the quarter, we also saw solid growth in advertiser spend across all key digital channels as customers are increasingly using the full omnichannel capabilities of our platform. Advertiser spend across mobile and desktop grew 56% year-over-year as we continued to benefit from the market disruption created by Apple's IDFA deletion. Across emerging channels such as streaming audio and digital out-of-home, advertiser spend grew 80% and 214%, respectively, during the quarter. CTV growth slowed, in part due to the difficult year-over-year comp, but also as a result of continued weakness across automotive and CPG. Excluding automotive and CPG, CTV spend grew 28% year-over-year. Investments in our sales, marketing and technology teams also continued to pay dividends during the quarter as evidenced by the significant increase in the number of active customers. At the end of Q2, we had 336 active customers, which compares to 288 in the prior year period, representing a net increase of 48 customers over the past 12 months for an increase of 17% year-over-year. Sequentially, the number of active customers increased by 9 compared to Q1, representing a quarter-over-quarter increase of 3%. Active customers using our percent of spend pricing option increased 37% year-over-year and 3% quarter-over-quarter. Average spend per active customer also increased 13% on a year-over-year basis. Moving down the P&L. Non-GAAP operating expenses, which is defined as the difference between contribution ex-TAC and EBITDA, totaled $34.8 million in the quarter, representing a year-over-year increase of 46% and a quarter-over-quarter increase of 11%. The year-over-year increase is primarily attributable to the investments we have made over the past 12 to 18 months across the organization to enhance our product capabilities and expand our sales team. As we have stated in the past, we have been investing to scale the business to accelerate growth and drive market share gains. However, as Tim discussed, given macroeconomic conditions, we intend to slow the pace of such investment in the second half of the year, focusing investments primarily across our product and engineering teams to ensure that we continue delivering on our long-term product vision, while maintaining profitability in the near term. Adjusted EBITDA of negative $3.1 million for the quarter was at the high end of our expectations, with lower non-GAAP operating expenses offsetting lower-than-expected revenue and contribution ex-TAC. For the quarter, our non-GAAP net loss, which excludes stock-based compensation, totaled negative $5.9 million and non-GAAP loss per diluted share of Class A common stock was negative $0.08 for the quarter. From a liquidity perspective, we ended the quarter with $207.2 million in cash and no debt. During the quarter, we repaid $17.5 million of outstanding debt previously drawn on our $40 million credit facility. With that, I'll now turn to guidance. As I mentioned earlier, we began seeing some marketers begin reducing budgets in June, and that trend is continuing into Q3. Our Q3 guidance reflects slower growth in advertiser spend across the platform relative to Q2 given these headwinds. For the third quarter of 2022, we expect year-over-year growth in advertiser spend of 20% to 25%. We expect revenue in the range of $47.5 million to $50 million, which represents a year-over-year decline of 2% to 7%. We expect our non-GAAP operating expenses to be consistent with what we saw in Q2 of 2022. And we expect adjusted EBITDA in the range of negative $1 million to $2 million. The uncertain macroeconomic environment is currently making it difficult to predict spend levels more than a few months out. As a result, we are only issuing guidance for Q3 at this time and are withdrawing our previously issued fiscal year 2022 guidance. In closing, we remain confident in our long-term targets of at least $500 million in revenue and 35% EBITDA margins by 2025. Our conviction is based on how marketers and their agencies are responding to our solution. We continue to win new customers and our existing customers continue to consolidate budgets across our platform and grow their spend. Our total addressable market provides significant opportunity to us, and we firmly believe that our solutions uniquely and effectively address many of the challenges that marketers are facing across today's dynamic digital landscape. That concludes our prepared remarks today. And with that, I will now turn it back over to the operator to open the lines for questions. Operator?
