Joining me today are Khozema Shipchandler, Chief Executive Officer, Aidan Viggiano, Chief Financial Officer, and Thomas Wyatt, Chief Revenue Officer. Definitions and reconciliations between our GAAP and non-GAAP results can be found in our earnings presentation posted on our IR website at investors.twilio.com. We will also make forward-looking statements on this call, including statements about our future outlook and goals. Twilio had a terrific Q1, accelerating revenue and gross profit to their highest growth rates in more than three years.
We delivered over $1.4 billion in revenue, up 20% year-over-year on a reported basis, and drove 16% growth in both organic revenue and non-GAAP gross profit. We also generated $279 million of non-GAAP income from operations and $132 million of free cash flow. 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 for AI natives and enterprises alike. Our voice channel revenue grew 20% year-over-year, marking its sixth consecutive quarter of accelerated growth, with AI being a catalyst.
For example, software add-ons such as Branded Calling and Conversational Intelligence both grew revenue more than 100% year-over-year. In just three months, the agent boosted its booking rates by 39%, capturing 6,500 appointments that otherwise would have been lost and generated $8.4 million in revenue. While Bland.ai committed to a multi-year partnership to use messaging, voice, and software add-ons such as recordings and Branded Calling to power their AI agent platform. Messaging revenue growth also accelerated in the quarter, aided by strong growth in WhatsApp and RCS.
