The Twilio Bootcamp is a week-long course that teaches every new employee at the company how to code and build on Twilio, with a focus on Messaging - one of their most popular products. The program was created to bridge the gap between sales, marketing, and software development teams, as customer empathy became a fading value in the growing company. Bootcamp has become an integral part of the employee onboarding experience in San Francisco, but expanding it globally proved challenging due to varying SMS regulations across countries. However, the integration with WhatsApp's Twilio API provided a solution, allowing students to use internet-based messaging and eliminating local handset requirements. The program's success lies in its ease of use, reliability, seamless integration with the Messaging API, and global reach, making it an attractive tool for scaling as Twilio continues to grow globally.
