Thank you, David, and good afternoon, everyone. We have a lot of exciting information to share on our 2024 results and Zeta 2028 plan. But before I get into the details, I want to lead with three main themes. First, consistency. Zeta has been incredibly consistent, beating and raising guidance for 14 consecutive quarters and increasing revenue 20% or greater, while also expanding our free cash flow margin for four straight years as a public company. Second, momentum. Our investment in an all-in-one marketing platform with AI and data at its core is creating accelerating momentum in our business, driving our fourth quarter record results and positioning us to target continuing to increase revenue at a 20% organic compound annual growth rate over the next four years. And third, rarity. There are over 500 public U.S. technology companies. Of those, only 23 are expected to increase revenue 20% or greater annually from 2021 to 2025. Of those 23, only 8 are expected to also expand their free cash flow margin annually from 2021 to 2025. Zeta is 1 of those 8, next to other great companies like Cloudflare, GitLab and Samsara included in this list. And as you will see with our Zeta 2028 plan, we expect to continue to do this for the next four years. Let's get into the fourth-quarter and full-year results. In 4Q, we delivered revenue of $315 million, up 50% year-to-year or 31% excluding LiveIntent and political candidate revenue. The full year revenue was just above $1 billion, up 38% year-over-year or 30% excluding LiveIntent and political candidate revenue. This exceeded our initial 2024 guide of $875 million by $131 million or 15%. Total scaled customer count grew to 527 as of December 31, 2024, up 17% year-over-year and 52 sequentially. LiveIntent added 34 customers to our scaled customer count and excluding this contribution, our scaled customer count increased 9% year-over-year. Super-scaled customers of 148 as of year-end were up 13% year-over-year and up 4% sequentially. LiveIntent added three customers to our super-scaled customer count. And as a reminder, we count each customer spending at least $1 million with us over the trailing 12 months as one super-scaled customer regardless of how many brands they are using us for. The number of brands spending at least $1 million with us over the trailing 12 months increased 28% year-over-year. Although customers using us for multiple brands does not benefit customer count, it does have a positive impact on ARPU. Scalable customer quarterly ARPU of $577,000 increased 27% year-over-year as reported and 32% when removing the impact of LiveIntent. Net revenue retention for the year was 114%, at the high end of our 110% to 115% range, an increase from 111% in 2023 and our highest level as a public company. From an industry perspective, in 2024, seven of our top 10 industries grew faster than 20% year-over-year with automotive, consumer and retail, insurance, political and advocacy, and technology and media growing the fastest. We ended the year with 180 quota carriers, an increase of 32% year-over-year, partly driven by our LiveIntent acquisition. Excluding LiveIntent, quota-carrying reps increased 20% year-over-year. Our direct mix in the fourth quarter climbed to 74%, up from 70% in the third quarter and slightly higher than 73% in the fourth quarter of 2023. For the full year, our direct revenue mix was 70%. Our GAAP cost of revenue in the quarter was 40%, a 20 basis point improvement from the fourth quarter of 2023 and up 60 basis points from the third quarter of 2024. For the full year, GAAP cost of revenue was 39.7%, up 210 basis points from 2023, mostly driven by a higher mix of integrated revenue due to our agencies initially adopting the social channel prior to increasing spend to direct channels over time. Leverage in other areas of our operating expenses resulted in our 16th straight quarter of expanding adjusted EBITDA margins year-over-year. In the fourth quarter, we generated $70.4 million of adjusted EBITDA at a margin of 22.4%, 110 basis points higher year-over-year and $4.5 million better than the midpoint of our guidance. We exceeded our adjusted EBITDA guidance despite incurring $2 million of additional expenses related to defending against the short seller report. To this point, our Audit Committee oversaw a review of the allegations, which involved engaging an independent forensic accounting firm to evaluate our shared customer and vendor accounting practices and internal controls. Additionally, we hired a leading data and privacy firm to assess our data and privacy practices. The reviews corroborated that our accounting practices were consistent with U.S. GAAP and that the data and privacy allegations in the short seller report were without merit. Additionally, the findings reinforced the strength of Zeta's internal controls and data privacy practices. For 2024, adjusted EBITDA was $193 million, representing a margin of 19.2% and a 49% increase year-over-year. In the fourth quarter, we achieved positive GAAP net income for the first time as a public company. Our fourth quarter GAAP net income was $15.2 million, which translated to earnings per diluted share of $0.06 in the quarter and a loss of $0.38 per share for the full year. Finally, fourth quarter cash from operating activities was $44 million, up 62% year-to-year with free cash flow of $32 million, up 74% and representing a margin of 10%. This translated to a free cash flow to adjusted EBITDA ratio of 45%. It's worth noting this includes a $22 million working capital headwind driven by growth with agencies and the industry's longer payment cycles. Absent this, cash flow conversion would have been 76%. This dynamic can be seen on Slide 26 in our earnings supplemental. For 2024, our free cash flow was $92 million at a margin of 9.2% and up 69% year-over-year. Now let's get into the details of our Zeta 2028 plan and 2025 guidance. I'll start with the Zeta 2028 plan, as many of the growth drivers and margin levers we will discuss for our medium-term plan are also applicable to 2025. Slides 15 through 20 in our earnings supplemental provide additional details. For revenue, we're targeting over $2.1 billion, which equates to at least a 20% organic revenue CAGR over the next four years. To put this in perspective, our revenue CAGR between 2021 and 2024 was 30%. Importantly, there's more than enough runway in our core business to achieve this target as we estimate we only have about 1% of our existing customers' marketing and advertising spend, and there is room to increase this penetration to 5% to 15% or more over time. We also have multiple new growth levers, some of which include; creating new GenAI capabilities. More GenAI features should drive additional usage of our platform, which we monetize through our consumption revenue as highlighted by David earlier. Leveraging the Publisher Cloud. This provides us with an opportunity to better monetize our extensive publisher relationships. Introducing new channels. We're still very early in mobile and plan to continue to enhance the product while also introducing new channels. Extending our vertical expertise. Through vertical-specific functionality, we can better penetrate verticals were underrepresented today, such as CPG, healthcare, commerce, and travel and expanding our partnership ecosystem. We believe this will drive pipeline growth and be beneficial for margins. The KPIs to achieve our 2028 plan looks very similar to our previous mid-term plan. We're targeting scaled customer count growth of 4% to 8% versus our three year CAGR of 14%. The biggest factor influencing this metric is our agency business, where we expect agencies to continue to add brands to our platform. However, regardless of how many brands and agency is leveraging Zeta for, it's only counted as one customer. From a brand count perspective, our growth will likely be around our historical scaled count trend. For scaled customer ARPU, we're expecting growth of 12% to 16%, in line with our three year CAGR of 15%. Our One Zeta initiative should positively impact channel and use case expansion, aiding ARPU growth. Further, the aforementioned agency dynamic will also have a positive impact on ARPU. We continue to expect net revenue retention to be in the range of 110% to 115%, in line with the 111% to 114% range that we achieved since 2021. And we expect our direct revenue mix to be 70% to 75%, roughly in line with the 70% to 77% annual range we've been in since 2021. Much like our initial medium-term plan, we're targeting significant margin improvement with our Zeta 2028 plan. Our 2028 adjusted EBITDA target of at least $525 million implies a 25% margin, an increase of 580 basis points or an average of 145 basis points per year. We expect to leverage across all areas of our business. Cost of revenue should improve by 100 to 300 basis points. We believe this will mostly be driven by a higher mix of direct revenue, which carries a lower cost of revenue as compared to integrated revenue. This should be driven by agencies ramping usage of direct channels, our One Zeta initiative driving more adoption of direct channels and higher margins from GenAI products and consumption scaling faster over time. Across our other operating expense lines, we anticipate 280 to 480 basis points of margin improvement. One key point of leverage for Zeta has been growing headcount significantly slower than revenue and adding a higher percentage of headcount outside of the U.S. Over the past three years, our revenue has increased at a CAGR of 30%, while total headcount has only grown at a CAGR of 15% with U.S. headcount growth even slower. Implementing AI internally should enable us to gain further headcount efficiencies. Expanding our partnership ecosystem will also create a margin tailwind. We expect future partners to take on some of the professional services we provide customers today, taking additional costs out of our business. From a free cash flow perspective, we're targeting $340 million plus in 2028, which equates to a CAGR of 39% from 2024. This represents a margin of 16%, an improvement of 700 basis points from 2024. In addition to the aforementioned margin levers, there are two additional factors driving our free cash flow margin improvement. First, we expect CapEx to grow materially slower than revenue. Our capital expenditures and capitalized software development was 4.2% of revenue in 2024, a significant improvement from 5.8% in 2021. Second, the impact of agencies on free cash flow should lessen over time as that business' growth comes more in line with Zeta's overall growth. Moving on to 2025 guidance. We're guiding to the midpoint of full year 2025 revenue to be $1.24 billion or growth of 23%. This includes LiveIntent revenue of $96 million. Adjusting for the impact of LiveIntent and political candidate revenue in the year-to-year comps, our excluding LiveIntent and political growth rate is 21%. A bridge is provided on Slide 25 in the earnings supplemental. As expected, our 2025 revenue guidance assumes there is no political candidate revenue. However, we are modeling for advocacy revenue to be between $20 million and $25 million as compared to $36 million in 2024 and $13 million in 2023. We're guiding to adjusted EBITDA at the midpoint of full year 2025 to be $256.5 million or a margin of 20.7%, a 150 basis point expansion year-over-year. We're guiding full year free cash flow to be $129.5 million at the midpoint, representing a margin of 10.4%, a 120 basis point improvement year-over-year and growth of 40%. Finally, on Slide 24 in the earnings supplemental, we've included quarterly 2025 guidance for revenue and adjusted EBITDA, a practice consistent with prior years. I'd like to conclude with this reflection. Anyone can issue a multiyear plan, but executing against it is another story. At Zeta, not only are we set to materially surpass our original Zeta 2025 plan, but we exceeded one of the key targets, revenue, an entire year ahead of schedule. For our Zeta 2028 plan, we kept the same KPIs and fine-tuned them to the most realistic path to achieve our goals. Just like with our original 2025 plan, we put extensive thought and diligence into our Zeta 2028 plan, which the entire company is focused on executing against and accountable for. With that, let me hand the call back over to the operator for David and me to take your questions. Operator?
