In two-sided markets, such as accommodation or mobility platforms, the relationship between increased supply and business outcomes (transactions, revenue) is not trivial. Factors such as seasonality, product quality, or local competition introduce biases that traditional statistical methods fail to isolate. This is where causal machine learning offers a decisive advantage: it allows estimating the incremental effect of adding a supply unit, controlling for confounding variables and heterogeneity across product segments.
The combination of double machine learning (also known as debiased ML) with a hierarchical Bayesian framework proves especially powerful. By incorporating prior knowledge (priors) and measures of geographic similarity between segments —taken from the geospatial literature— more stable estimates with better out-of-sample performance are obtained. This approach, applied for example at Airbnb, can be generalized to any marketplace that needs to understand the return of expanding its catalog.
Implementing this type of model requires a robust technological ecosystem. Not only is a causal inference engine needed, but also the capacity to process large volumes of data, integrate geographic sources, and deploy models in production. At Q2BSTUDIO we develop custom applications that address precisely these challenges: from building data pipelines to orchestrating AI models. Our team combines expertise in artificial intelligence with deep business knowledge to design solutions that truly deliver value.
Additionally, to scale these solutions safely and reliably, we offer AWS and Azure cloud services, which guarantee the elasticity needed to train complex models. Cybersecurity is another fundamental pillar: when handling sensitive transaction and user data, we implement protection measures from the design stage. And once estimates are ready, Power BI dashboards or our business intelligence services allow product teams to clearly visualize the impact of supply.
The trend toward intelligent automation also drives the use of AI agents that, based on these causal models, can recommend in real time which new supply units to launch or in which segments. At Q2BSTUDIO we accompany companies on this journey, from conceptualization to the implementation of AI for businesses with a practical and measurable approach. If your marketplace truly needs to understand the return on its supply, having custom software that integrates causal ML, cloud, and BI is the most solid path.
