Twilio has made the difficult decision to restructure and reduce its workforce by approximately 11% due to rapid growth, which led to a lack of focus on company priorities. The layoffs are aimed at aligning investments with four key priorities: platform reliability and trust, messaging profitability, Segment adoption, and Flex customer scaling. Twilio's CEO, Jeff Lawson, takes responsibility for the decision and acknowledges that it will be hard for impacted employees but believes it is necessary to ensure the company's future success.
