MarketOS unifies identity, journeys, sending and attribution for 412 B2B teams across 24 countries — so finance, marketing and product argue from one number.











“We replaced three tools with MarketOS in six weeks. The Governance Gate caught a suppression mistake that would have cost us a regulator letter. Maria Konstantopoulou's onboarding team is the most rigorous I have worked with in fifteen years of CRM.”
“We were sending 4.1 million emails a month and apologising for half of them. After Attribution Studio showed us the incrementality of the bottom 60%, we cut sends by 42% and revenue per send went up 11%. Andreas Vlachos personally walked us through the model — that does not happen with US vendors.”
“Journey Studio is the first lifecycle tool I have used that ships with version control. We run 47 active journeys and the diff view alone has saved us two production incidents this quarter. Trial-to-paid is up 19% on the strength of three Audience Lab segments.”
“We are a regulated bank. Every vendor we evaluated failed at audit log granularity and DPA terms. MarketOS passed both, and the Sofia Halberg-led security team answered our 187-question infosec questionnaire in nine business days.”
“I have used HubSpot, Marketo, Pardot and Iterable. MarketOS is the first platform where the model my CFO sees is the same model I plan against. We retired two BI dashboards within a month of switching.”
