SessionM

A leading enterprise loyalty and customer engagement platform bridging AdTech and MarTech, with strong traction in retail, QSR, and CPG verticals prior to its acquisition by Mastercard.

SessionM was a Boston-based customer loyalty and engagement platform founded in 2012 that helped brands design, manage, and optimize loyalty programs and personalized marketing campaigns. The platform enabled enterprises to collect and analyze customer behavioral data across multiple touchpoints — including mobile apps, web, and in-store — and use those insights to deliver targeted rewards, offers, and experiences that drove repeat engagement and purchase behavior. The company's core offering evolved from a mobile advertising and rewards network into a comprehensive customer data and loyalty management platform. SessionM's technology allowed brands to unify customer profiles, track engagement across channels, and automate personalized outreach through a combination of loyalty mechanics, gamification, and CRM-style segmentation tools. This positioned SessionM at the intersection of AdTech, MarTech, and loyalty technology — a differentiated niche that attracted major enterprise clients in retail, restaurant, CPG, and financial services. In 2019, Mastercard acquired SessionM, integrating its loyalty and customer engagement capabilities into Mastercard's broader suite of data and services products. The acquisition reflected Mastercard's strategic interest in expanding beyond payments into loyalty, personalization, and merchant marketing services. Following the acquisition, SessionM's technology and team were absorbed into Mastercard's loyalty and engagement solutions portfolio, effectively ending its existence as an independent brand.
