Case Study: Outschool saves 3,000 engineering hours and personalizes user experiences with Twilio Segment

How Outschool saves 3,000 engineering hours annually and delivers more relevant experiences with Segment

Outschool, a San Francisco–based online education marketplace, faced a massive surge in demand during the COVID-19 pandemic (2,000%+ increase in class bookings) and an influx of customer data from multiple sources and regions. To better understand users and scale quickly, the company needed a Customer Data Platform (CDP) fast and chose to buy rather than build to avoid diverting engineering resources.

By adopting Twilio Segment, Outschool centralized first‑party data to power personalized class recommendations, 1:1 messaging, and targeted marketing integrations (Iterable, Google, Facebook). The platform sped integrations from months to weeks, saved about 3,000 engineering hours per year, and made the organization more agile—boosting engagement, retention, and the ability to rapidly test and deploy new experiences.
