Case Study: AT&T Mobility saves 2 million work hours annually with MuleSoft API-led connectivity

AT&T saves 2 million work hours annually by adopting API-led connectivity

AT&T faced a fragmented integration landscape where customer- and service-facing teams had to pull data from more than 50 legacy systems connected via brittle point-to-point integrations. This lack of a single source of truth caused long hold times, slow resolutions, poor ability to upsell, and a subpar experience for 180 million customers and 9,000 Mobility Services and Support agents.

AT&T deployed Salesforce Customer 360 powered by MuleSoft to create API-led connectivity, building 50+ APIs that aggregate data into a single Salesforce platform. The move delivered secure, reusable APIs (75% reuse), accelerated time to market eightfold (from ~12 months to 6 weeks), and saved about 2 million work hours annually by cutting administrative work and speeding access to customer data.
