ResponseTap

ResponseTap is a UK-founded call-intelligence and call-tracking technology company that connects digital marketing touchpoints to phone-call conversions so marketers and contact centers can measure and optimize the calls that drive revenue.[3][5]

High-Level Overview

ResponseTap builds a call-intelligence platform that links online customer journeys to inbound phone calls, providing campaign-level and visitor-level call tracking, speech analytics, and phone-call attribution for marketers and call centers.[3][5] Founded in 2008 and today part of the Infinity group, ResponseTap’s product helps organizations attribute calls to channels/keywords, improve campaign ROI, and optimize call-handling to increase sales and reduce call time.[2][3] The company serves marketers, performance agencies, and contact centers—customers include large brands across industries—and emphasizes integrations across martech stacks so phone conversions are visible alongside digital conversions.[5][7]

Origin Story

ResponseTap began from a conversation between two university friends, Ross and Richard, who saw a disconnect between online behavior and offline phone sales; within two years they launched campaign-level tracking and later visitor-level tracking, earning early recognition such as placement in the Telegraph’s Tech Start-Up 100 list.[3] The company was founded in 2008, grew to serve over a thousand brands, raised institutional funding (total disclosed around $15.29M), and in March 2021 was acquired by Infinity to combine call tracking and speech-analytics capabilities.[2][3] Early traction included rapid customer acquisition and the first European integrations with Google Analytics for visitor-level call attribution.[3]

Core Differentiators

• Call-intelligence focus: Provides granular campaign- and visitor-level attribution that ties web touchpoints to the phone call, not just aggregate call counts.[3][5]
• Integrations and martech compatibility: Built to integrate with analytics and advertising platforms so call data feeds into bidding and marketing optimization workflows.[3][5]
• Speech analytics and AI features (post-acquisition enhancements): The Infinity acquisition expanded access to more advanced call analytics and speech-insight features for customers.[3][2]
• Enterprise credibility and customer base: Used by large brands and agencies (G2 cites major clients such as Aviva and Virgin) and widely reviewed in the martech community.[7][5]
• Operational tooling for cost and engineering efficiency: Example customers have used cloud-cost intelligence and operational tooling to drive product-margin improvements while scaling the service.[4]

Role in the Broader Tech Landscape

ResponseTap is riding trends around measured multichannel attribution, the persistence of phone-driven conversions for high-value purchases, and the need to unify online and offline conversion data for accurate marketing ROI.[5][3] Timing matters because marketers increasingly optimize paid spend with machine learning models that require accurate offline conversion signals—call attribution supplies a high-value, previously opaque signal.[5] Market forces in their favor include sustained mobile and voice usage for purchase journeys, growth in contact-center automation and speech analytics, and stronger integration expectations across martech stacks.[2][5] By making call conversions analyzable and actionable, ResponseTap helps bridge a longstanding gap in marketing measurement and influences how agencies and brands value phone-driven revenue in performance models.[3][5]

Quick Take & Future Outlook

ResponseTap’s immediate path is continuing product integration and capability expansion under Infinity—especially deeper speech analytics and tighter martech integrations—to keep phone calls first-class conversion data for performance-driven marketers.[3][2] Trends that will shape their journey include greater use of AI for real-time call routing and conversation insight, continued pressure for unified attribution across channels, and the commoditization of basic call-tracking (which favors vendors offering analytics, speech intelligence, and enterprise integration).[4][5] If ResponseTap continues to evolve its AI/speech features and preserve strong integrations, it is well positioned to remain a leading call-intelligence provider for brands that still rely on phone sales—keeping phone conversions visible in increasingly automated, data-driven marketing stacks.[3][5]
