The Chief Marketing Technology Officer of a major European retail conglomerate recently shared, with the mixture of pride and exhaustion common to survivors of corporate transformation programmes, that her organisation had reduced its marketing technology stack from two hundred and seventeen applications to one hundred and nine over the preceding eighteen months. The target, she noted, was eighty.

This trajectory — from excess to consolidation — is playing out, with varying degrees of speed and pain, across virtually every enterprise marketing function of scale. The era of "best-of-breed" point solutions, which defined MarTech procurement philosophy from approximately 2010 to 2023, has given way to an era characterised by three forces simultaneously: budgetary pressure from CFOs who view SaaS sprawl as an unacceptable operational risk; the maturation of platform vendors whose AI-augmented suites now legitimately replicate the functionality that had previously required specialist tools; and the growing recognition, among marketing leadership, that data fragmentation across dozens of systems imposes integration costs that consume the efficiency gains those systems were purchased to deliver.

The Gartner MarTech survey for 2026, released in June, found that enterprises reported using an average of forty-two marketing technology tools, down from sixty-three in 2024. More significantly, the utilisation rate — the proportion of purchased capability that was actively used — rose from thirty-one per cent to forty-seven per cent over the same period. The two trends are related: reducing the number of tools concentrates usage on those that remain.

The consolidation has been particularly acute in the middle of the stack — the layer of analytics, content management, and automation tools that sat between the customer data platform and the execution channels. Historically, this middle layer was where specialisation thrived: a tool optimised for email deliverability, another for landing page testing, a third for marketing attribution. What AI has done to this layer is to make it economically viable to build all three functions into a single platform, because the marginal cost of adding an AI-powered capability to an existing system is substantially lower than it was when those systems required hand-coded feature engineering.

The vendors accelerating through this consolidation share certain characteristics. They have invested heavily in data integration, ensuring that the platform's AI models have access to unified customer data rather than siloed slices. They have prioritised explainability — not in a technical sense but in a business sense, ensuring that marketing professionals can understand and trust the recommendations the AI produces. And they have built governance workflows that allow human override without creating the friction that would cause practitioners to circumvent them.
