Buying an ad takes a moment. Everything around it can take weeks. Centro, now Basis Technologies, built its business in that gap.
Every beautiful website has an unglamorous back room. Cloudinary turned that room into a service, then grew to $100 million in annual recurring revenue before Blackstone bought a stake.
Basis Technologies is a Chicago-based advertising software company that builds Basis, an automation and intelligence platform for digital media. Founded in 2001 as Centro and rebranded in 2021, Basis unifies programmatic, publisher-direct, search, social, and connected TV buying alongside campaign planning, workflow automation, reporting, and financial reconciliation - so agencies and enterprise marketers can run cross-channel media from a single system.
Olyzon is an AI-native adtech company building an agentic decisioning and orchestration layer for Connected TV (CTV) advertising. Founded in 2024 and headquartered in Paris with offices in New York and London, its platform sits on top of the fragmented CTV ecosystem - agnostic across every DSP, SSP and direct publisher - and uses AI agents to qualify inventory at the program level, plan and activate campaigns, adapt creative to viewing context, and normalize measurement into unified outcomes. The company has powered hundreds of campaigns for global brands and agencies, and closed a $10M Series A led by Sir Martin Sorrell and Sanja Partalo's S4S Ventures in May 2026.
