Seam Tech Stack

Universal API layer for IoT device automation and access control

IT Services and IT Consulting San Francisco, CA 11–50 employees Founded 2020 Privately Held

Seam abstracts away fragmented IoT manufacturer APIs—smart locks, thermostats, sensors, access control systems—behind a single unified interface. The tech stack (TypeScript, Python, PostgreSQL, Z-Wave, Zigbee, BACnet) reflects deep protocol expertise; active projects span backend API maturity, design systems handling high-scale request volumes, and TypeScript tooling for faster integration. Leadership is senior-weighted with minimal recent hiring, suggesting a focus on consolidating product-market fit rather than rapid hiring growth.

About Seam

Seam provides a universal API and managed platform that lets software teams integrate IoT devices without negotiating directly with manufacturers or maintaining protocol-specific logic. The platform normalizes smart locks, thermostats, sensors, and access control systems into a single abstraction layer, then layers on workflow automation, embedded UI components, a customer portal, and direct connectors to property-management and industry systems. Founded in 2020 and based in San Francisco, Seam serves software platforms and integrators across property management, hospitality, and access control—teams that would otherwise spend months on custom device integrations per brand.

Frequently Asked Questions

What IoT protocols does Seam support?

Seam integrates Z-Wave, Zigbee, and BACnet protocols directly, normalizing them into a single API. The platform also handles direct HTTP APIs from major smart-device manufacturers and property-management systems.

What tech stack does Seam use?

Core stack includes TypeScript, Python, Ruby, and PostgreSQL for backend services. Device communication uses Z-Wave, Zigbee, BACnet, and MQTT. Monitoring and observability run on Datadog and Grafana.
