Machine learning is leveling the ad measurement landscape for disruptor brands
A first-of-its-kind experiment demonstrates how new technology is lowering traditional barriers to entry for marketing mix modeling as access to user data declines.

For large organizations, marketing mix modeling (MMM)—a statistical technique that quantifies the impact of marketing and nonmarketing activities—has long been a powerful tool for measuring and optimizing ad campaigns across channels. In recent years, as marketers have grappled with declining access to personal data amid a rapidly evolving advertising landscape, MMM has emerged as a vital, privacy-centric alternative to user tracking because it does not not depend on cookies or unique identifiers.
But disruptor brands—startups that are born online and use innovative approaches to challenge established companies—have traditionally shied away from MMM, viewing it as too time- and resource-intensive to build and implement.
Now, a large-scale first-of-its-kind experiment commissioned by Meta and conducted by Accenture shows that MMM, when coupled with machine learning techniques and granular data, can produce budget-friendly and actionable insights for marketers across all sizes and verticals, without requiring the use of personally identifiable information.
The work highlights that technical innovations have democratized marketing mix modeling and significantly reduced the resources required to deploy MMM. Today’s models can deliver highly accurate, cost efficient predictions that can be customized to include variables especially valuable to disruptor marketers—such as purchases, app installs and subscriptions. These insights can then be used to optimize strategies ranging from budget allocation and campaign tactics to creative approaches and messaging.
Barking up the right measurement tree
The experience of Bark showcases how today’s marketing mix modeling can deliver valuable insights for brands of all types. A company best known for its monthly subscription services for pet owners—including BarkBox, Super Chewer, BARK Bright and BARK Eats—Bark also sells its products via direct-to-pet-parent channels, online marketplaces and a network of retailers.
In 2021, Bark wanted a budget-friendly approach to measure the effectiveness of its marketing spend and determine the optimal budget allocation mix. Specifically, the company was looking to evaluate its customer acquisition costs in a consistent way across channels, including Meta, search, email, linear TV and e-commerce platforms. It also wanted to understand what impact efforts such as press releases, news blurbs, website content and promotional offerings were having on driving subscriptions.
Bark turned to Robyn, Meta Open Source's MMM code, which uses machine learning algorithms to limit human bias and ensure accurate reporting. This free and open source approach is highly customizable and ideal for analytical teams that are resource-strapped.

With Robyn, Bark was able to build its first model in just three months. It rapidly delivered cost-efficient, actionable insights, such as recommending a budget to optimize for new subscriptions, along with a prediction for how many new subscriptions a channel’s suggested budget would yield. These insights helped drive a 30% increase in subscriptions and powered sustained growth for the business.
Four best practices for getting started with MMM
With new technologies and online resources available, brands can now take multiple approaches to building their own MMM. These range from a complete DIY strategy where everything is handled internally to partnering with a full-service consultancy, to handle all building, management and reporting—or a hybrid path where the internal analytics team fills in any gaps in expertise with semi-automated, self-service tools.
While getting started with MMM can seem daunting—especially for disruptor brands—the measurement approach is accessible if the right foundation is put in place, according to study results.
Here are four recommended best practices to get started with MMM:
As the advertising ecosystem evolves and access to personal data continues to decline, brands that wait to embrace MMM will increasingly face measurement challenges. By starting along the path now, disruptor brands can determine which solutions best fit their goals, timelines and budgets. Once this foundation is laid and MMM is in place, marketers will gain rich cross-channel insights, discover valuable optimizations and position their businesses for lasting success in the privacy-first age and beyond.
