Business Description

Our Company We are an advertising technology company. Our cloud-based demand side platform ("DSP") enables the programmatic purchase of advertising, which is the electronification of the digital advertising buying process. Programmatic advertising is rapidly taking market share from traditional ad sales channels, which require more staffing, offer less transparency, and involve higher costs to buyers. Our DSP is used by marketers and their advertising agencies to centralize the planning, buying and measurement of their digital advertising across most channels. Through our omnichannel platform, a marketer can easily buy ads on connected TV ("CTV"), streaming audio, digital out-of-home, mobile and desktop. Our DSP is an easy-to-use self-service platform that provides our customers with transparency and control over their advertising campaigns. Once a marketer describes their campaign objectives, they can choose to maintain hands-on control over every campaign detail or have our platform autonomously execute, optimize, and measure their advertising investments. Our platform offers customers unique visibility across a variety of inventory, allowing them to create customized audience segments and leverage our proprietary Household ID ("HHID") and strategic partner data to reach target audiences at scale. Our platform delivers a full suite of forecasting, reporting and automation that provides our customers with insights into available inventory based on the desired target audience. We offer advanced forecasting and reporting that empowers our customers with functionality designed to ensure they can accurately measure and improve their return-on-advertising spend (“ROAS”) across channels. Marketers use our platform to deliver advertising campaigns to their desired target audience across channels and formats. Through platform integrations, we offer our customers access to omnichannel advertising inventory, which refers to media available across devices, channels and formats. Our platform supports a full range of transaction types including real-time bidding, private marketplace and programmatic guaranteed, allowing customers to easily source and integrate ad inventory directly from publishers and private marketplaces. We enable deep data access through our data integrations to authenticate user identities across a range of devices. Our HHID enables us to be the nexus point with more than 70 data partners, providing customers with deep access to data across market verticals such as automotive, entertainment, professional services, retail, consumer packaged goods, travel and tourism, and healthcare. Our HHID solution empowers marketers to reach people across their devices, whether individuals are at home or away from home, without the use of cookies. Leveraging patented technology, our HHID technology cuts through more than 1.8 billion IP addresses and other identifiers and translates them into 125 million households. Our identity graph links these households to an estimated 1 billion connected devices. Our customers are advertising buyers including large advertising holding companies, independent advertising agencies, mid-market advertising service organizations as well as marketers that rely on our self-service platform for their programmatic ad buying needs. We are a trusted partner to our customers as exemplified by our customer satisfaction rating of over 90% in 2025 based on Viant’s Annual Customer Satisfaction Survey. Many of our customers use us as their primary DSP. Using our identity resolution capabilities led by our patented HHID and identity graph, marketers and their advertising agencies can identify targeted consumers using real-world identifiers rather than relying primarily on cookies to track users. We believe the industry is shifting to replace cookies in delivering personalized advertising, particularly for identification. Our HHID allows marketers to deliver personalized advertising while being able to accurately link ad impressions across multiple devices and to customer sales and measure the impact of their ad spend. Many of our competitors rely on cookies for the targeting and measurement of digital advertising but this technology has not been effective at accurately measuring the real impact of a marketer’s ad spend on their business results. Apple’s web browser, Safari, has added controls that algorithmically block or limit some cookies, and other browsers and platforms have added similar controls.…
