Persona.ly worked with our long-time partner, digital marketing agency Pipar\TBWA, to re-engage users of the Waitr app. These users had installed the app but never converted to paying customers by purchasing Waitr’s food delivery service.
Our ultimate goal was to bring users, living in specific US cities where the service is available, back to make their first purchase and become engaged, recurring customers.

Our in-house DSP is integrated with all the major SSP platforms and is constantly processing more than 1.5M QPS of in-app inventory. For each auction, we apply user-level targeting via our machine-learning algorithms to run effective UA and retargeting campaigns. Our algorithms are based on real-time request data and aggregated data from our DMP.
With Dynamic Audiences — our proprietary segmentation engine available to our clients at no extra cost, eliminating the need to use a third-party tool — we quickly defined user segments based on their in-app behavior and current stage in the Waitr funnel. By analyzing unattributed data provided by the client as well as insights from past campaigns, we generated a segment of users in the later stages of the funnel who hadn’t completed it. This allowed us to drive a high volume of first purchases.
Shortly after gathering a representative number of conversions (re-engagements and re-installs), we were able to leverage our attributed data to narrow down our target audience and focus on users with a higher probability of becoming loyal, returning customers. This allowed us to consistently reduce the CPA and exceed the KPI by a significant margin.
Once we had collected enough sample data for our machine learning models to classify between 1) users who were likely to convert by making a first purchase and 2) non-converting users who would not make a purchase, the bottom line KPI—the CPA—began to steadily decrease. The original segmentation already produced results well below the KPI, and the additional layer of optimization from classification allowed an even steeper decrease.
Two different CPA KPIs were provided – one for the initial exploration period of one month, and another, 25% more aggressive, for the following period when enough data was accumulated.
Within the first weeks of running the campaign, we were able to exceed the exploration KPI, generating CPA 19% lower than the target. During the second month of running the campaigns, we were able to exceed the aggressive KPI, generating conversions at 19% lower than the target CPA.
An additional layer of optimization was required due to the prominence of first-price auctions, an auction model recently adopted by most SSPs. In first-price auctions, the highest bidder wins the impression for the exact price they bid. This is opposed to second-price auctions, where the first bidder still wins, but the price per bid is determined by the second-highest bid (+$0.01). This increases the risk of significantly overpaying for impressions.
Bid shading is a technique of predicting the market price of an auction and allowing DSPs, which can forecast bid price, to avoid overpaying while maintaining scale. Processing 1.5M requests per second, Persona.ly’s DSP has both machine learning models and enough data to efficiently predict the lowest price to win the impression.
Due to careful, personalized creative selection, we immediately saw high CTR that continued to improve MoM as scale increased. Shortly after the campaign started, we analyzed the data to predict best-performing hours where the budget should be spent and set up proper time-based pacing.
