OuterSignal, the agentic customer intelligence platform helping consumer businesses personalise to every customer, has announced the acquisition of Monocle, an AI-powered lifecycle marketing platform that replaces rules-based flows with autonomous, 1:1 customer journeys across email, SMS, and web.
Two Halves of the Same Problem
For years, brands have faced the same gap: surface-level or stale customer data led to generic marketing execution and lacklustre customer experiences. OuterSignal was built to close the first half, deploying agents to harness publicly available data to understand, segment, and engage with the actual person behind every purchase.
Monocle closes the second: its AI agents evaluate purchase intent, discount sensitivity, and engagement timing for every individual customer, then act without waiting for a marketer to build a flow.

When unified, the platform delivers true 1:1 personalisation – identifying who customers are and what they care about, and then activating them when, where, and how they want to be messaged.
“Generative AI makes possible the long-standing promise of 1:1 personalisation, but requires a deep understanding of each and every human on the other side,” said Zach Zelner, OuterSignal’s Co-Founder and CEO.
“OuterSignal tells you who your customers are. Monocle takes action with that intelligence. We’re excited to combine our platforms to enable marketers to scale highly personalised experiences, agentically.”
“When OuterSignal approached us, the fit was obvious,” said Noam Szpiro, Monocle’s Co-Founder and CEO. “They’ve taken a unique approach to tackling the upstream customer intelligence opportunity that makes a product like ours even more powerful. Together, the story is complete.”
What This Means For Monocle Customers
Existing Monocle customers will continue using the product without disruption. OuterSignal will take over account management and support immediately, with deeper platform integration planned over time.
