Neuwo

What Neuwo does

Neuwo is a Finland-based contextual AI company founded in 2022 by Johannes Harju that builds proprietary NLP and machine learning models for semantic content classification, brand safety assessment, and audience targeting without relying on cookies or user-level tracking data. Its technology stack reads the full text — and in newer Edge API iterations, images and video — of articles and web pages to assign IAB-aligned categories, brand safety verdicts, and semantic topics from a pre-built taxonomy of 10,000+ topics across 100+ languages. Models are trained and served on the LUMI supercomputer, an EU-hosted, hydroelectric-powered infrastructure, with EU data residency and on-premise deployment available for regulated customers.

The product portfolio spans five primary surfaces: a Classification API and Auto-Tagging API for document-level classification; a Bid Enrichment service that injects contextual signals into OpenRTB 2.x bid requests at sub-100ms latency for programmatic monetization; a Contextual Audiences product for advertisers activating segments across the open web and CTV; and, following the 2026 acquisition of Kiosked's ad technology, a full Monetisation Platform combining header bidding orchestration, high-impact ad formats, and AI-agent-driven yield optimisation. Distribution is hybrid: a self-serve API channel for developers and mid-market customers, plus enterprise field sales targeting publishers and advertisers across DACH, Benelux, UK, US, and Latin America. Neuwo generates revenue through per-document API usage fees and fixed monthly subscriptions with annual commit options; named customers include Sanoma, Kurier, Alma Media, Colgate, Jack Daniel's, Naviga, and Newsroom AI, and the platform is embedded into PubMatic, Prebid, Xandr, Equativ, Index Exchange, Google Ad Manager, The Trade Desk, Yahoo DSP, and DV360.

Core offering

Neuwo is a contextual AI company that provides AI-powered content classification, brand safety scoring, and bid enrichment APIs for publishers, advertisers, and ad-tech platforms. Following its 2026 acquisition of Kiosked technology, Neuwo now also offers a full publisher monetisation platform combining its contextual AI with proven ad technology, header bidding orchestration, and SSP integrations. All offerings operate without cookies or user tracking, leveraging proprietary NLP models running on the EU-based LUMI supercomputer.

Product overview

Neuwo is a contextual AI and monetisation solutions company offering a platform-plus-modules architecture. The core offering combines Neuwo's contextual AI intelligence layer — which reads and understands content at depth using proprietary NLP models — with Kiosked's acquired (2026) ad technology and monetisation infrastructure. The platform is organised into publisher-facing products (Monetisation Platform, Bid Enrichment, Auto-Tagging API) and advertiser-facing products (Contextual Audiences), plus developer APIs (Classification API, Python/JS SDKs) and custom enterprise solutions. All products are privacy-safe, operate without cookies or user tracking, and are built on EU-based sustainable infrastructure (LUMI supercomputer, hydroelectric energy).
