Saperly
The first phone carrier built only for AI agents — real numbers, real caller ID, MCP-native.
Video Review
About
Saperly launched on May 5, 2026 with a claim no other telco can make: every line on the network belongs to an AI agent. Not a human with a chatbot bolted on. Not a call-center IVR. An agent — and the carrier was designed around that fact from the protocol up. Here is the problem Saperly fixes. If you have ever wired a Twilio or Vonage number into an AI agent, you already know the pain. The phone number was provisioned for humans. The caller ID rotates. The voice stack assumes a human picks up. The compliance layer (TCPA disclosures, consent capture, audit log) is your job to build. By the time the agent is legally clean and operationally stable, you have written a thousand lines of glue code and your customer service agent still gets flagged as spam. Saperly's stack assumes the caller is the agent. Each agent claims a real, stable phone number. The caller ID stays consistent across every call and SMS the agent sends, so carrier reputation builds the way it does for a small business. Voice, SMS, intelligent routing and compliance all live behind one MCP-native API — a single account, a single bill, no separate Twilio + Vonage + compliance vendor + audit-log SaaS stack. The compliance layer is the part most teams will care about. It is optional, but if you turn it on, every line gets disclosure scripts, consent capture and a structured audit log without you writing any of it. For an outbound agent calling US numbers, that is the difference between "passes legal review" and "blocked at the GC's desk." Setup is the unsexy part Saperly nails. Create an account, claim a line, wire a webhook, your agent is live in seconds. Number rental and monthly usage settle on the saved card — no separate procurement workflow, no multi-day porting wait, no purchase order. Compare that to the typical Twilio enterprise onboarding (verified-caller registration, A2P 10DLC campaign approval, shaken/stir attestation) and the gap is a week of paperwork versus an afternoon of webhook config. The honest critique: Saperly is brand new. As of launch on May 5, 2026, the network is single-region and the founder — Vaibhav Sisinty — announced it on X with a working demo, not a multi-year case-study reel. Twilio and Vonage have a decade of carrier relationships, redundancy and global coverage Saperly cannot match yet. If your agent needs to call internationally on day one, this is not the carrier. If you are deploying a US-domestic agent and tired of building telephony glue, Saperly takes the work off the floor. Affiliate program: none yet. Saperly has not launched a public partner or referral program, and we will not link to one that does not exist. Recheck in 60-90 days as the company scales. Where it fits in the stack: for governance over the agents using these phone lines, see Microsoft Agent 365. For multi-agent orchestration that pairs well with agent telephony, look at PageIndex for retrieval and PageIndex MCP for serving long-context document search to the same agent that picks up the call.

- 5Outbound notification agents (delivery updates, appointment reminders) that need carrier-grade SMS
- 6Compliance-sensitive deployments in finance, healthcare or legal where audit logs are non-negotiable

Pros
- Designed agent-first from the protocol up — no human-handoff assumptions to work around
- Consistent caller ID per agent means deliverability improves as the agent calls more
- Compliance layer eliminates the disclosure / consent / audit-log glue every team currently rebuilds
- MCP-native API drops cleanly into Claude, Cursor, Codex and any other MCP-aware agent
- Setup is genuinely seconds — claim line, wire webhook, dial out
- Single bill replaces the typical Twilio + compliance vendor + analytics stack
Cons
- Brand new as of May 5, 2026 — no multi-year track record on uptime or carrier relationships
- Single-region focus at launch (US-domestic). International coverage is not on the public roadmap yet
- No public price list — you need to sign up to see numbers, which slows enterprise procurement
- Smaller carrier blast radius than Twilio or Vonage if a regional outage hits
- No affiliate or partner program yet — reseller economics are unclear at launch
