What Seedtag does

Seedtag is a global AdTech company headquartered in Madrid, Spain, founded in 2014 by Jorge Poyatos and Albert Nieto. It builds and operates a Neuro-Contextual advertising platform anchored by its proprietary AI engine "Liz," which combines artificial intelligence with neuroscience principles to interpret interest, emotion, and intent signals across the open web, online video, and Connected TV (CTV). The platform serves two primary customer segments — advertisers/brands/agencies seeking privacy-first, cookieless targeting across display, OLV, and CTV; and premium publishers (30,000+ globally) monetizing inventory via contextual audiences, contextual profiles, dynamic placement optimization, and brand-safe ad serving. Notable customer logos include Unilever, Gillette, Heineken, NBA, JetBlue, Applebee's, Renault, Orange, The Washington Post, Marie Claire, Sky, and Forbes.

Seedtag's core technology stack centers on Liz, supported by an AI Intention Models layer (April 2025), Custom AI for personalized machine learning models (October 2022), Contextual Audiences and Contextual Profiles, computer vision and image recognition for brand safety, and the Extra Blend creative effect. The April 2026 launch of NeuroX, a Neuro-Contextual Exchange that embeds Liz directly into programmatic infrastructure before impressions enter the bidstream, marks a strategic shift toward an exchange-based, hybrid self-serve distribution model. The March 2026 launch of Liz Agent, a RAG-based agentic AI interface, extends Liz from a targeting engine into a strategic collaborator for media planning. The company integrates with measurement and supply partners including xpln.ai, HUMAN Security, Adelaide, Nielsen, Lumen, IMPACT+, and Xandr Curate, and operates Beachfront's CTV supply-side platform following its June 2024 acquisition. The CTV channel is monetized via Beachfront's premium inventory and the Contextual TV solution (March 2024).

Seedtag's business model is advertising-driven and quote-based, monetizing Liz AI and NeuroX through programmatic and direct contextual campaigns (Display, OLV, CTV) for advertisers and agencies, alongside publisher monetization services via login.seedtag.com. Revenue is usage/transaction-based, with disclosed regional growth signals including +120% YoY in North America (2024), +88% in the US (Q1 2025), +38% in the UK (H1 2025), and +46% YoY in North America (2026). The company operates 15 offices across 16 markets (EMEA, North America, LATAM, Middle East, APAC) with 700+ employees, and has raised over €250M from Advent International (July 2022) and $40M Series B from Oakley Capital (2021). Enterprise field sales remain the dominant go-to-market, complemented by event-led demand generation, thought-leadership content (AdTech Collective blog, Seedtag Insights, Seedtag Academy), and an emerging programmatic/PLG motion via NeuroX.

Revenue model

1. Programmatic & direct contextual advertising: Primary revenue stream: Seedtag monetizes its Liz AI / Neuro-Contextual platform by delivering targeted advertising campaigns (Display, OLV, CTV) for advertisers and agencies via programmatic channels (NeuroX exchange, direct deals) and through publisher inventory. Reported revenue growth indicators include 120% YoY growth in North America in 2024, 88% US revenue growth in Q1 2025, 38% YoY growth in UK in 2025 H1, and 46% YoY growth in North America in 2026 — pointing to a usage-based / transaction-driven advertising model.
2. CTV advertising (Beachfront inventory): CTV-specific advertising revenue following the Beachfront acquisition in June 2024, which integrated direct premium CTV inventory and sell-side ad platform capabilities for streaming and connected TV advertising, with CTV ad spend referenced as expected to exceed $30 billion in 2024.
3. Publisher monetization services / supply-side platform: Seedtag also generates revenue from the supply side, providing publishers with contextual targeting and monetization tools (Contextual Audiences, Contextual Profiles, Dynamic Placement Optimization) and offering publisher access via login.seedtag.com.

Seedtag offers a Neuro-Contextual advertising platform anchored by its proprietary AI called Liz (the core intelligence that interprets interest, emotion, and intent signals). Built around this AI are several connected products: NeuroX, the Neuro-Contextual Exchange that embeds Liz directly into programmatic infrastructure; Liz Agent, an agentic AI conversational interface for media strategy built on a RAG framework; LAB, a strategic services program that uses AI to define cookie-less strategies; the Curation Platform for self-serve agency capabilities; and channel-specific solutions including Contextual TV for CTV and offerings for OLV (Online Video) and Display. Supporting products include Contextual Audiences, Contextual Profiles, Custom AI, AI Intention Models, and Dynamic Placement Optimization. Acquired platforms that have been integrated include Beachfront (CTV sell-side platform), JustEggs (Australian creative intelligence), and KMTX (French AI for performance optimization). Together, these form a unified neuro-contextual OS spanning advertisers, publishers, and channels (CTV, OLV, Display).
