Realize your full data potential.

Semasio is on a mission to harness the power of predictive intelligence now and in the future. We help data-driven marketers connect and build trust with consumers safely by creating access to a world where ads align with the content customers consume - the responsible way to drive growth in a privacy-first world.

Beyond targeting. Customer connection.

We’re helping advertisers and agencies move beyond the status quo. Our next-generation semantic intelligence delivers a better understanding of your customers–so you can plan and execute more successful advertising campaigns or do more to leverage your first-party data.

With expertise that lies at the intersection of human behavior, semantic technology and real-time targeting, Semasio delivers a suite of solutions that enables marketers to effectively reach consumers across devices, now and in the future. Operating across 50 countries and delivering semantic targeting in over 30 languages, our capabilities have earned the trust of a diverse and global client base, including Fortune 500 companies, agency networks, emerging brands and leading data partners.

Founded in 2010 in Hamburg Germany, Semasio was acquired in 2022 by Casters Holdings, Inc., a US-based company operating under the Fyllo brand name. The combined entity, now called Semasio, is the leading provider of next-gen targeting solutions.
