Chord buys Zenlytic and its data analyst agent, Zoë

AdExchanger puts the price at $5 million. Chief executive Bryan Mahoney told it the combined business has an annual run rate nearing $10 million, with some 60 customers and around 30 full-time employees. Mahoney said Zoë “largely replaces” the analyst agent Chord built itself.

Chord now calls itself an agentic version of a CDP (customer data platform), the software that gathers a brand’s customer records in one place. One Chord client, Sonos, uses it to add detail to its own customer data, for instance to notice when a buyer is moving home, a moment Mahoney sees as right for an email or text about new products. Mahoney wants Zenlytic’s larger clients to adopt Chord for segmenting audiences for campaign targeting and measurement.

Chord bills by usage, and its agent now receives a question about every 20 seconds, Mahoney said. In the release he warns brands against handing control of their business knowledge to OpenAI and Anthropic.

Klaviyo sells its own marketing agent on a usage meter too. On our AI email tools page, its Composer add-on is $20 a month for four times the free plan’s usage, and the free plan carries $5 of Composer usage a month, our 8 November check.

Because Chord bills by usage, a Zenlytic client that moves onto Chord pays more the more its staff ask, the same pattern Klaviyo’s Composer tiers show on our sheet.
