Q1 revenue of $1.41 billion grew 20% year on year, the highest reported rate since 2022, as the cloud communications platform repositions itself as enterprise voice AI infrastructure.
Twilio raised its full-year 2026 revenue growth forecast to 14-15%, up from 11.5-12.5%, after reporting first-quarter results that beat expectations across every major metric on Thursday.
The cloud communications platform reported revenue of $1.41 billion, up 20% year on year on a reported basis and 16% organically, the company’s fastest organic growth rate since 2022. Shares jumped roughly 18% in extended trading.
CEO Jeff Lawson attributed the acceleration explicitly to AI-driven demand for voice and messaging. “In Q1, we continued to see unprecedented demand for voice reimagined through the lens of AI, which is increasingly an entry point to the Twilio platform,” Lawson told analysts on the earnings call.
Voice revenue grew 20% year on year, the sixth consecutive quarter of acceleration. Software add-ons including Branded Calling and Conversational Intelligence each grew more than 100%.

The numbers behind the upgrade
Non-GAAP earnings per share of $1.50 cleared the consensus estimate of $1.27 by approximately 18%, and revenue of $1.41 billion exceeded the $1.34 billion consensus by 5.2%. The company had originally guided February investors to Q1 revenue of $1.335-1.345 billion, making the result a meaningful beat.
Free cash flow reached $132.3 million in the quarter. The dollar-based net expansion rate, a closely watched metric for SaaS investors that measures how much existing customers are spending year on year, improved to 114%, up from 107% a year earlier, indicating customers are expanding their use of the platform rather than churning.
Alongside the revenue guidance raise, Twilio lifted its full-year non-GAAP operating income outlook to $1.08-1.10 billion, up from $1.04-1.06 billion previously, and projected free cash flow in the same range.
Q2 guidance of $1.42-1.43 billion in revenue exceeded analyst estimates and implies the momentum should carry through the year. Several deals during the quarter were described by management as ‘seven-figure agreements,’ indicating substantial enterprise contract values.
CFO Khozema Shipchandler emphasised the cost discipline that has accompanied the growth. “We have achieved significant milestones in reducing stock-based compensation and controlling operating expenses,” he said.
The combination of accelerating revenue and improving margins is exactly what investors had been waiting for from a company that had spent two years rebuilding its profitability profile after years of growth-first spending.
Voice AI as the new growth engine
The strategic story behind the numbers is the repositioning of Twilio from a developer-focused communications API platform into what Lawson is now describing as enterprise voice AI infrastructure.
“Our voice AI innovations are not only driving growth but also positioning Twilio as a leader in AI-driven communication solutions,” Lawson said.
The transition is significant. Twilio’s historical strength has been programmable SMS and voice APIs that developers stitch into their own applications. The current growth driver is something different: pre-built voice AI agents that operate across customer engagement, sales, and support workflows, with conversational intelligence and branded calling layered on top.
That repositioning runs into a substantial competitive field. ElevenLabs has scaled to $330 million in annual recurring revenue and an $11 billion valuation, with the company’s ElevenAgents platform targeting customer support, sales automation, and internal enablement, the same enterprise voice AI workflows Twilio is now building into.
Sierra, founded by former OpenAI and Salesforce executive Bret Taylor, has reached unicorn status on its conversational AI platform. Anthropic and OpenAI both offer voice agent capabilities through their model APIs that any enterprise developer can build on directly.
Twilio’s defensible position in that landscape comes from its installed base. The company has the underlying telecommunications infrastructure, the carrier relationships, the global phone number inventory, the regulatory compliance work, that voice-AI-native startups need to access in order to deliver actual phone calls and SMS messages.
The strategic question is whether Twilio can convert that infrastructure advantage into a higher-margin AI applications business before the AI-native competitors build, partner, or acquire their way to a comparable telecommunications layer.
The Q1 numbers suggest the conversion is at least underway. Voice revenue accelerating for six straight quarters, software add-ons growing more than 100%, and a dollar-based net expansion rate climbing seven percentage points are all signs that existing Twilio customers are buying more, not just more of the same.
Whether that pattern continues at the rate the new guidance implies, in a market where the underlying AI capabilities are being commoditised by every model provider, will determine whether the 18% share price reaction was a momentum trade or a structural revaluation.
One pressure point worth noting: increased carrier fees continue to weigh on gross margins, the company said. The economics of voice AI scale through Twilio’s platform are partially exposed to telecommunications carrier pricing power that Twilio does not control. Management did not characterise this as a near-term threat to the guidance, but the dynamic is one investors will want to track as voice AI volumes ramp.
