Twilio (TWLO)

Programmable communications APIs (SMS/voice/email/CPaaS) plus a model-agnostic agentic conversation layer — embed messaging, voice and AI agents in apps; usage-based

AI exposure 8% — derived from reported segment revenue, not asserted.

Where it sits

Software Stack → Enterprise & Business Software · figures rebased to Q2 2026, reported 2026-08-06

Programmable communications APIs — Messaging (SMS/WhatsApp/RCS), Voice, Email (SendGrid)… leads 2 businesses in this sub-tier that together are 100% of revenue, so Enterprise & Business Software is effectively the whole company rather than one leg of it.

Reported segments

Twilio Communications — 93% of revenue
Segment (customer data platform) — 7% of revenue

Twilio (~$5.6B TTM; Q2 2026 revenue $1.499B, +22% reported / +17% organic) — communications platform (CPaaS) now positioning as the conversation layer for AI agents. Communications ~93% (Messaging SMS/WhatsApp/RCS + Voice + SendGrid email APIs, usage-based, carrier fees passed through) + Segment CDP ~7% — note Twilio stopped disclosing the Communications/Segment revenue split from Q3 2025, so the 93/7 is rolled forward from the last disclosed quarters, not a current disclosure.

How the 8% is built

Twilio Communications — 93% of revenue × 8% AI-driven (estimate). No disclosed AI revenue. Raised from 5% because Q2 2026 organic growth accelerated to 17% and the FY organic guide went 9.5-10.5% -> 13-13.5%, with management attributing the step to AI-native voice cohorts (ConversationRelay call volume tripled QoQ, self-serve voice above 50%, AI-native customers +~60% YoY in voice…
Segment (customer data platform) — 7% of revenue × 12% AI-driven (estimate). Segment profiles now feed Conversation Memory, the agentic layer's persistent-context product, and Twilio was named a Leader in the 2026 IDC MarketScape for AI-enabled CDP — but Segment revenue is no longer separately disclosed and no AI contribution is quantified

Investment read

Moat. CPaaS developer lock-in and carrier-interconnect scale — embedded application code, registered A2P campaigns and deliverability reputation make migration real work — plus a Segment CDP attach and, since SIGNAL 2026, a conversation layer (Orchestrator, Memory, Intelligence) that holds cross-channel state. Q2 2026 showed the switching cost compounding rather than eroding: DBNE 116% and customers spending $1M+ annually up more than 20%. The messaging itself is commoditised, and Agent Connect is deliberately open-source and model-agnostic, so the lock-in lives in the integration and the state…

Bottleneck / pricing power. Moderate and structurally squeezed at the transport layer: US A2P carrier fee pass-throughs cut non-GAAP gross margin 160bps YoY to 49.1% in Q2 2026 (+60bps excluding them), with roughly 210bps of full-year drag guided and ~$250M of incremental gross-up for the year. The offset is expansion rather than price — DBNE 116%, up from 114% and 109%, of which only about 5 points is carrier fees, with $1M+ customers up more than 20% and software add-ons growing 25%.

Role in the AI stack. The communications-API (CPaaS) layer for apps + AI agents.
