↓ -6%Twilio has unveiled new AI-powered customer engagement platform capabilities for Latin America, aiming to address persistent communication challenges in customer service. The company is introducing four features: Agent Connect, Conversation Orchestrator, Conversation Memory, and Conversation Intelligence, designed to maintain conversation continuity across different channels and touchpoints. A Twilio Customer Insights Series report revealed nearly all surveyed businesses struggle with understanding customer preferences and unifying data across channels. For Q3, Twilio projects revenue between $1.505 billion and $1.515 billion, representing 16% to 16.5% growth year-over-year, with organic revenue growth expected at 11% to 12%. However, analysts note risks from intense competition with Zendesk, Salesforce, and cloud providers, alongside exposure to Latin America's economic uncertainties and regulatory challenges.
Twilio has surged 57% in 2025, outperforming Palantir Technologies (down 3%) and SoundHound AI (down 29%) as demand for AI software accelerates. Gartner projects AI software spending will jump 60% this year to $453 billion. The cloud communications specialist reported second-quarter revenue of $1.5 billion, up 22% year over year, with non-GAAP earnings per share rising 23% to $1.47. Organic revenue grew 17%. Twilio's improving growth stems from its AI tools, which help clients predict customer behaviour, build AI agents, and automate workflows. One automotive fintech client using Twilio's conversational AI platform saw lead conversion increase 1.6 times, leading to a seven-figure deal. The company has expanded beyond its core application programming interfaces for voice, text, email, chat, and video communications.
