API origins and early growth
Jeff Lawson, Evan Cooke, and John Wolthuis founded Twilio in 2008. The company launched Twilio Voice, a cloud-hosted API, on November 20, 2008. In May 2010, GroupMe launched at the TechCrunch Disrupt hackathon using Twilio’s text messaging product. Twilio released its text messaging API in February 2010 and SMS shortcodes in July 2011. The company raised $103 million in venture capital growth funding, including a $17 million Series C round in December 2011 and a $130 million Series E in July 2015 from Fidelity, T Rowe Price, Altimeter Capital Management, Arrowpoint Partners, Amazon, and Salesforce. Twilio went public on the New York Stock Exchange on June 23, 2016, with a 92 percent increase in share price on the first day. The company expanded through various acquisitions, including Authy in February 2015, Tikal Technologies for $8.5 million in September 2016, and Beepsend in February 2017. In May 2021, Twilio acquired Ionic Security for $30.2 million and Zipwhip for $850 million. The October 2018 acquisition of SendGrid for $2 billion became a $3 billion deal when the companies formally merged in February 2019.
Segment acquisition and the restructuring
Twilio acquired Segment, a customer data platform, for $3.2 billion in October 2020. This acquisition faced pressure from activist investor firms Anson Funds and Legion Partners, who pushed for a divestiture in 2023 and 2024. Between September 2022 and June 2025, Twilio shed roughly four thousand employees. This period included an 11 percent layoff in September 2022, a 17 percent cut of 1,500 employees in February 2023, and a 5 percent reduction in December 2023. The workforce dropped from a 2022 peak of nine thousand to the mid-5,000s by 2026. You know the basics of the CPaaS market, so I will focus on the restructuring. While the company leadership focuses on voice AI, much of the senior Segment engineering talent migrated to competitors like Snowflake and Databricks, marking a significant shift in the industry landscape. I find the unevenness of these cuts particularly jarring because the company restructured into Communications and Data & Applications units while Segment talent migrated to competitors. The layoffs primarily targeted the Bay Area and Dublin, though later rounds reached into Bangalore and Bogota. Displaced talent from the communications side moved to competitors like Bandwidth, Sinch, and Vonage. Segment alumni specifically moved to companies like Hightouch, Census, and RudderStack. In August 2022, attackers accessed the internal network through an SMS phishing campaign, which impacted enterprise customers like Signal. The hackers obtained data from 209 customers and compromised 93 Authy accounts during the breach.
The AI voice pivot and new era
The company pivot focuses on AI voice agents. In the first quarter of 2026, revenue reached $1.39 billion, with voice channel revenue rising 20 percent year over year. AI-native customers like Bland.ai and Scorpion signed significant deals for messaging and voice services. Scorpion’s AI agent drove an $8.4 million revenue lift for the customer. Twilio also secured a seven-figure Verify contract with a historic professional sports league. Car Finance 247 moved from private beta into a seven-figure agreement using its AI assistant, Carla, which handled roughly 288,000 conversations. Khozema Shipchandler leads the company following Jeff Lawson’s January 2024 departure. Messaging grew 25 percent on the back of WhatsApp and RCS traction. Twilio also integrates with tools like Claude Code and Replit to support developers building agents throughout their workflows. The company continues to push the Verify and ConversationRelay product lines as cross-sell motions for the sales organization. Revenue from customers spending more than $1 million annually grew more than 20 percent. Will the voice AI momentum sustain the company’s growth?
