Martech Stack Issues Trace to Missing Ownership and Governance
MarTech examines why martech tools fail to deliver after 18 months despite initial investment in segmentation, data quality, and personalization.
A CMO confronted her martech stack after 18 months of spend produced flat campaign velocity and conflicting numbers from two reporting tools.
Overlapping Tools and Untracked Integration Costs
The stack stated that the customer data platform and marketing automation platform both built audiences from the same data yet defined segments differently. It added that API updates broke integrations and required ongoing engineering resources that had never appeared in the CMO’s subscription tracking.
According to MarTech (https://martech.org/if-your-martech-stack-could-talk-what-would-it-say/), the organization’s accounting framework captured only tool subscriptions and did not record the cost of keeping the stack running as a connected system.
Familiarity Without Capability
The stack explained that training sessions covered button-level tasks such as building a segment, setting an identity rule, and exporting to a channel. It noted that the team still lacked the capability to decide which segment to build for a campaign planned for the next quarter or to structure exports differently for the MAP versus the ad platform.
The first 60 days after go-live set the performance ceiling because no subsequent work embedded these practices into team routines.
Performance Drift and Tool Accumulation
The stack reported that it had been configured for the business at launch. New channels, volume, and expectations later emerged, yet uptime, error-rate, and throughput data received no follow-up action, allowing drift.
A tool originally purchased for a team reorganized 18 months earlier continued to renew automatically. No process existed for removing tools. The original stack owner changed roles a year ago, leaving the stack without an assigned owner.
Connecting Activity to Business Results
The stack stated that it reports activity but not capability. No role had been assigned to translate its output into outcomes the CMO could present to finance.
According to MarTech (https://martech.org/if-your-martech-stack-could-talk-what-would-it-say/), the organization requires a dedicated function with headcount, budget authority, and the power to discontinue tools that no longer earn their place.
The article concludes that responsibility for managing the stack as a system, maintaining integrations, and linking output to results must be explicitly assigned rather than left to default procurement and renewal processes.
