Twilio was founded in 2008 by Jeff Lawson, Evan Cooke, and John Wolthuis to let software developers send calls and text messages without negotiating with telecom carriers. A few lines of code against Twilio's API replaced carrier contracts and telephony hardware.
Developer-First Growth
Twilio marketed to engineers rather than executives, offering free trial credit and detailed documentation. Developers built prototypes, then brought Twilio into their employers. Ride-hailing, delivery, and messaging apps became large early customers.
Acquisitions and Expansion
After its 2016 NYSE IPO, Twilio added email with SendGrid in 2019 and customer data with Segment in 2020, aiming to move beyond low-margin message routing.
Restructuring
Revenue grew quickly through the pandemic, but losses topped $1 billion in 2022 and 2023. Twilio cut staff, faced activist investor pressure, and Jeff Lawson stepped down as CEO in January 2024. Khozema Shipchandler took over and focused on profitability.
2025-2026
Twilio posted its first full-year GAAP profit in 2025 on $5.067 billion of revenue, bought identity company Stytch, and grew Q2 2026 revenue 22% to $1.50 billion as AI agents drove more voice and messaging traffic.
