Our take
Traditionally, it has been difficult for businesses to establish communications systems in-house. Twilio was founded from frustration with this expensive and cumbersome process, providing easy-to-use APIs to let businesses send and receive telephone and text communications.
From these beginnings, the company has expanded through acquisitions and product development to provide a suite of services around market data and customer engagement. It is now a market leader in this space, and has developed a customer base of more than 150,000 businesses including enterprise brands such as Deliveroo, Duolingo and Toyota.
Although aggressive expansion and lack of maturity in some of its products in the past impacted the company's efficiency, a 2023 restructuring addressed these problems and allowed it to remain competitive. The company has since focussed on profitability, streamlining decision making and R&D to put itself in good stead for future success.
