Seam

Seam provides a universal API and fully managed, no-code toolset that makes it incredibly easy for software platforms to integrate, automate, and orchestrate IoT devices across industries. Instead of negotiating with manufacturers, handling inconsistent APIs, or building custom logic for every brand, teams rely on Seam to unify smart locks, thermostats, sensors, and full access control systems under one simple layer—no integration work required.

Seam was built to solve one of the hardest problems in software: device integrations. Manufacturer APIs are inconsistent, require lengthy business development, and demand ongoing maintenance. Companies often repeat this work across multiple brands—costing months of engineering time before they can ship a single feature. Seam removes that complexity and now goes far beyond integration.

Alongside our universal API, Seam offers a suite of ready-to-use products that accelerate time to market:

A unified API that normalizes and extends manufacturer APIs

SDKs that speed up development

Embedded UI components for instant device-management interfaces

Authentication flows to connect third-party device accounts

A fully managed Customer Portal with prebuilt UI for end users to connect, map, and monitor devices—no-code

Automation Workflows that sync access with reservations, issue codes, manage climate, and more

Connectors that integrate directly with PMS and industry systems so teams can deploy automation with zero integration work

With Seam, teams can orchestrate powerful automations—issuing mobile keys, generating time-limited codes, adjusting climate, syncing reservations, or unifying building operations—without building integrations or custom workflows.

Today, Seam powers software across short-term rentals, hospitality, multifamily, commercial real estate, fitness, education, and more.

We make IoT work for software—so teams can focus on delivering exceptional experiences, not managing integrations.
