In 2026, Mark Ritson utilized Mutinex to conduct a marketing mix modeling (MMM) analysis on his MiniMBA platform. The study found that a 25% increase in paid channel spending generated only a 2% increase in revenue, highlighting the diminishing returns of scaling paid acquisition.
Why it matters
Marketing organizations are increasingly adopting aggregate measurement strategies as signal loss and weakened user-level attribution make traditional tracking less reliable. This shift reflects a broader industry movement away from granular targeting toward econometrics to validate spend effectiveness.
MiniMBA trained 50,000 marketers over a decade, with an annual enrollment of 8,000 to 9,000 students. The global marketing mix modeling software market is estimated at $2.23 billion for 2026, projected to grow to $4.22 billion by 2031.

Mark Ritson

MiniMBA

The details
The analysis integrated CRM data, owned and earned media, and external economic factors into a 12-week program curriculum. Organizations are utilizing frameworks like Google's open-source Meridian, released in January 2025, to normalize disparate data sets. This transition toward econometrics allows companies to quantify the performance of broader campaigns, despite Forrester’s forecast that marketing measurement confidence will decline by 7% in 2026.
Timeline
January 2025 marked the release of the Google Meridian framework.
Early 2025 served as the period for MiniMBA's 25% increase in paid channel spending.
2026 is the year of the Cannes Lions conference and the $2.23 billion market estimate.
2031 is the year the MMM software market is projected to reach $4.22 billion.
Market Landscape
The move toward econometrics is a response to the erosion of third-party tracking, positioning tools like Google's Meridian framework as essential infrastructure. This trend signals a departure from granular attribution toward aggregate analysis as the industry prepares for a forecasted decline in measurement confidence.
Operators should review whether their current attribution models rely too heavily on user-level data that may be failing. Use this period of market transition to re-evaluate the ROI of paid channels using econometrics rather than simple click-through metrics.
The takeaway
Marketing performance often follows a curve of diminishing returns that requires constant econometric auditing to identify. Track the percentage of your budget allocated to high-reach, low-attribution channels versus direct-response efforts to ensure your spending remains efficient.
