Semasio (formerly Fyllo)

What Semasio (formerly Fyllo) does

Semasio (formerly Fyllo) is a data intelligence and advertising technology platform that sells semantic and contextual targeting products to brands, agencies, and data providers operating in a privacy-first, cookieless environment. The company's core technology uses natural language processing to analyze page content and build 128-term semantic profiles for both pages and consumers, enabling audience targeting, audience extension (semantic twins), contextual targeting, brand-fit scoring, and the ContextualPLUS product that combines audience accuracy with contextual reach. Supporting offerings include the Factory platform for first-party data onboarding, modeling, and programmatic distribution; Media Strategy & Activation services; Hypertail PMP for long-tail media; and Interactive Screens for in-store retail digital signage inherited via the NineSixteen acquisition.

The company is structured as Semasio Inc. (US) and Semasio GmbH (Hamburg, EU controller), with offices in San Francisco and Hamburg and a historical Chicago headquarters from the Fyllo era. Semasio was acquired by Fyllo in April 2022; Fyllo is itself owned by Samba TV, creating a multi-tiered ownership structure. Revenue is generated through four streams: subscription/recurring SaaS for audience targeting, data monetization through the data marketplace, professional services for media strategy and activation, and managed services for data providers. Pricing is quote-based with an enterprise field-sales motion supplemented by self-service access for power marketers. The customer base spans verticals including pharmaceutical, automotive, cannabis, and travel, with named logos such as Audi Denmark, PubMatic, The Farmer's Dog, TVadSync, Poland Spring, Cityrow, and Columbia Care.

The platform holds multiple privacy certifications (ePrivacy GmbH, EDAA OBA Framework, IAB TCF #84, NAI membership via Samba TV, IAB Global Privacy Platform), which it leverages as a wedge into regulated verticals and EU markets. Headcount is reported at 51-100, and the company has raised approximately $99M across multiple funding rounds from 2019 through 2023, including a $40M Series C led by Eminence Capital in November 2021.
