AI-READY INFRASTRUCTURE

Anyone can build an agent. We ensure yours are reliable, secure, and compliant at global scale

74% of enterprises have had to roll back an AI deployment because the infrastructure couldn’t sustain it. (Sinch AI Study 2026)

Sinch gives you the secure foundation that removes that problem. It connects systems of action to systems of record, and AI agents to the customers they need to reach – all while ensuring context is never lost along the journey.

HOW SINCH COMPARES

Infrastructure built smarter from the ground up

Most communications providers route through four to six intermediaries before a message reaches a carrier. Sinch is built to mitigate all that unnecessary risk, routing directly to Tier-1 carriers wherever those connections exist, with smart aggregation only where they don’t.   

We own more of the value chain than any other provider in our category – which means fewer hops on average, better deliverability, and one clear owner when something needs to be fixed.

FAQ

Frequently asked questions about Sinch Infrastructure

Most providers route messages through four to six intermediaries before a message reaches a carrier. Each hop adds latency, increases the chance of failure, and spreads accountability thin. The Sinch network connects directly at one to two hops – 600+ carrier connections – which means measurably better deliverability, lower latency, and a clear owner when something goes wrong.

No. Sinch differs from aggregator-based providers in five ways: direct carrier routing (1-2 hops vs 4-6), native channel breadth, embedded compliance, native AI agent support, and same-network fallback routing.

Most providers have added AI capabilities on top of existing infrastructure. That means agents still hit the same routing bottlenecks, compliance gaps, and channel limitations as everything else. Sinch is built as an agentic platform from the infrastructure layer up. Multi-agent, multi-model environments are natively supported. AI agents connect directly to CRMs, CDPs, and systems of record – so context isn’t lost across channels or interactions.

You can bring your own. Sinch is designed as an open agentic architecture. Build with Sinch APIs, bring your own agents and models, or integrate partners into the platform. We support multi-agent and multi-model environments and don’t require you to standardize on a single AI ecosystem.

Compliance is built into the Sinch infrastructure – not layered on as an afterthought. We have local regulatory expertise in 60+ countries, with certifications including ISO 27001, SOC 2 Type II, HIPAA, GDPR, STIR/SHAKEN, and 10DLC. When regulations change in a specific market, that’s managed at the infrastructure layer. Your team doesn’t have to track it manually or rebuild integrations to stay compliant.
Fallback routing runs natively within Sinch infrastructure – on the same network, not through a third-party integration. If a primary channel fails, messages reroute automatically via SMS with no additional setup required. Because Sinch owns the network, there’s no handoff latency and no accountability gap.  

Sinch routes at one to two hops rather than through multiple intermediaries. That eliminates the markup-at-each-layer model that drives up costs with aggregator-based providers. What you’re quoted reflects the actual cost of delivery.

Yes. Sinch connects systems of action – AI agents and LLMs – with systems of record, including CRMs, CDPs, and enterprise data (HubSpot, Salesforce, Shopify, Adobe, etc.). Native connectors and an API-first architecture mean your communications infrastructure works with the tools your business already runs on. No custom integrations to build and maintain.
With Sinch, compliance controls – fraud detection, identity verification, data residency, and regulatory registration – are enforced at the infrastructure layer. They’re not optional add-ons you configure on top. That means they apply consistently across every channel, every message, and every market, without additional setup per region or per use case. For regulated industries like healthcare and finance, that distinction matters.
