Twilio -- How the Business Works
Twilio is the global leader in CPaaS, providing programmable APIs for messaging, voice, video,
email, and identity/authentication. ~85% of revenue is usage-based (pay per API call/message/minute),
creating natural operating leverage as customers scale. The company serves 400K+ active customer
accounts across 180+ countries via 4,800 carrier interconnections. FY2025 revenue reached ~$5.1B,
with the usage-based model creating a direct link between customer growth and Twilio revenue.

Revenue by Product -- FY2025
| Product | Revenue | % of Total | YoY Growth | Trend |
|---|---|---|---|---|
| Messaging | $2,878M | 57% | +22% | Accelerating (carrier fees + AI volume) |
| Voice | $616M | 12% | +13% | Accelerating (AI catalyst, +20% in Q1'26) |

Revenue Model -- Usage-Based Pricing
| Product | Pricing Model | Unit Economics |
|---|---|---|
| Messaging | Per-message fee | ~$0.0079/msg US (SMS), varies by country. Carrier surcharges passed through. |
| Voice | Per-minute fee | ~$0.0085/min inbound, ~$0.014/min outbound US |
| Email (SendGrid) | Tiered plans + overage | Subscription tiers with per-email overage pricing |
| Verify | Per-verification fee | Per authentication event, channel-dependent |
| Segment (CDP) | Subscription + usage hybrid | Platform fee + tracked user volume |
Key dynamic: ~85% usage-based means revenue scales directly with customer activity.
More AI agents making calls, sending messages, and verifying identities = more API calls = more
revenue with minimal incremental cost to Twilio. This is the ideal business model structure for
the AI agent thesis.
Key Business Metrics -- Quarterly Trend
| Metric | Q1 '24 | Q2 '24 | Q3 '24 | Q4 '24 | Q1 '25 | Q2 '25 | Q3 '25 | Q4 '25 | Q1 '26 |
|---|---|---|---|---|---|---|---|---|---|
| Active Customers | 305K | 309K | 313K | 317K | 328K | 342K | -- | -- | -- |
| DBNE | 103% | 102% | 106% | 108% | 108% | 109% | -- | -- | 114% |
DBNE inflection: Dollar-based net expansion bottomed at 102% in Q2 2024 and has
re-accelerated to 114% in Q1 2026 -- the highest level since 2022. This reflects both organic
customer growth and AI-driven volume expansion on existing accounts.

AI Agent Infrastructure Thesis
Twilio as AI Agent Infrastructure
Twilio is positioning as foundational infrastructure for AI agents. Voice AI revenue is growing
60%+ YoY. AI natives -- Sierra, Bland.ai, Retell AI, PolyAI -- are deepening
platform relationships and scaling rapidly on Twilio's infrastructure. ConversationRelay and
Conversational Intelligence add-ons are growing 100%+ YoY. Multi-channel
orchestration with persistent memory is launching at SIGNAL in May 2026.

Per-call / per-msg revenue
Reality check: Management says AI contribution is "not super meaningful" yet --
estimated ~$60-80M on a ~$5B revenue base. Early innings. The thesis is about trajectory, not
current contribution.
Assessment
Usage-based model is the ideal structure for the AI agent thesis -- more agents
= more API calls = more revenue with minimal incremental cost to Twilio. The 400K+ customer base
across 180+ countries with 4,800 carrier interconnections creates a regulatory and operational
moat that's nearly impossible to replicate. Multiproduct adoption accelerating (29% growth)
and DBNE at 114% show platform stickiness.
The risk: messaging at 57% of revenue has the lowest margins, and its share is growing -- creating a structural mix headwind on gross margins even as volume and revenue accelerate. Carrier surcharge pass-throughs inflate the top line but dilute margins. The bull case requires Voice and Verify (higher-margin products) to grow faster than Messaging over time, and for AI agent volume to accelerate that shift.
