FIELD NOTES

Turning sleep technology into a shippable product.

Engineering perspectives on smart mattresses, private data platforms, mobile experiences and agent interfaces.

A smart mattress is a stack, not a feature

Why sensing hardware, apps, data infrastructure and agent interfaces have to be designed together.

Data residency becomes simpler when the architecture separates a customer data plane from a narrow cloud control plane.

How to expose useful sleep tools to agents without turning MCP into an authorization bypass.

What mattress brands should preserve—and what they should customize—when launching a sleep app.
