Semasio

Semasio creates value by transforming advertiser, publisher, and partner data into addressable audience and contextual assets that can be activated across programmatic media buying workflows. Its platform ingests seed data across identifiers, enriches it through semantic modelling, and distributes resulting segments into buying environments. Around that software layer, it also offers managed media activation and curated marketplace access, allowing customers either to self-serve data activation or buy execution support.

Semasio is a Germany-based adtech company focused on privacy-safe audience and contextual targeting for programmatic advertising. Its product set includes data onboarding and modelling, contextual intelligence, audience extension, brand suitability, and audience distribution into programmatic buying environments. The company serves advertisers, agencies, publishers, and data owners that want to activate first-party or partner data without relying solely on third-party cookies.

It generates revenue through a combination of software access, data monetisation, and managed services. In addition to platform-led offerings such as Semasio Factory and contextual targeting, the company also offers media strategy and activation services and curated private marketplace access via Hypertail PMP. This gives it a hybrid model spanning SaaS-style tooling, data usage or licensing economics, service fees, and marketplace margins.
