Ad Tech

Ad tech, a child sector within Superscout's Marketing & Advertising Tech category, encompasses the technology platforms that automate the buying, selling, targeting, measurement, and optimization of digital advertising across display, video, social, connected TV, retail media, and emerging channels. With 48 funders actively investing in ad tech startups tracked in Superscout's database, the sector draws capital from media-focused venture funds, consumer internet investors, and enterprise software generalists who see advertising as a massive and increasingly technology-driven market. Ad tech companies raised $786 million in equity funding across 72 rounds in 2025, a 151% increase compared to 2024, driven by the AI transformation of creative production, targeting, and measurement in a post-cookie advertising landscape.

The ad tech investment thesis in 2025-2026 is defined by two structural shifts: the deprecation of third-party cookies and mobile advertising identifiers creating demand for new targeting and measurement approaches, and generative AI transforming creative production and campaign optimization. Global digital advertising spend reached approximately $740 billion in 2025, growing 15% year-over-year, with AI-powered creative production ($85 billion subsector), programmatic optimization, connected TV advertising, and retail media networks representing the fastest-growing categories. Koah raised $20.5 million in Series A funding from Theory Ventures and Forerunner for its AI-native advertising platform, illustrating the category of AI-first ad tech companies that is attracting the most venture interest.

Superscout's stage data shows 39 funders (81%) at seed, 27 (56%) at pre-seed, 20 (42%) at Series A, 4 (8%) at Series B, and 7 (15%) at growth equity. The median minimum check is $175,000, median maximum is $1 million, and the 75th percentile reaches $2.75 million. The modest check sizes reflect the software-first nature of ad tech startups, which can often reach product-market fit with relatively small teams and limited capital. The steep drop from Series A (42%) to Series B (8%) reflects the challenge of scaling ad tech companies to venture-relevant outcomes in a market dominated by Google, Meta, Amazon, and The Trade Desk.

Privacy-first advertising technology represents the most structurally important investment category. With third-party cookies being phased out across browsers and Apple's App Tracking Transparency limiting mobile identifier access, the entire digital advertising ecosystem needs new infrastructure for targeting, attribution, and measurement. Companies building first-party data platforms, contextual targeting engines, clean room technology for privacy-preserving data collaboration, and new measurement methodologies that do not rely on individual tracking are addressing mandatory demand from advertisers and publishers adapting to the post-cookie world.

Retail media networks, where retailers monetize their first-party purchase data and on-site traffic by selling advertising to brands, have become one of the fastest-growing channels in digital advertising. Retail media ad spending exceeded $50 billion in 2025, with Amazon, Walmart, Instacart, and dozens of other retailers building advertising businesses. The technology infrastructure powering retail media, including ad serving, audience management, campaign optimization, and measurement platforms, represents a growing venture opportunity.

For ad tech founders, the 2025-2026 funding environment rewards AI-native products with demonstrable performance advantages, proprietary data or workflow integration that creates switching costs, and clear unit economics. Investors want crisp revenue recognition (distinguishing gross from net revenue), strong payback periods, and defensible competitive positions in a market where the dominant platforms control most of the ad spending and can replicate point solutions as features.
