A smart mattress is a stack, not a feature
Why sensing hardware, apps, data infrastructure and agent interfaces have to be designed together.
6 minThe visible feature is only the last mile
A sleep score inside an app depends on installation, signal quality, identity, report boundaries and a stable data contract. Treating the score as an isolated feature pushes integration risk into every customer project.
One model across every surface
A member, device assignment, report and activity should mean the same thing in iOS, Android, REST, CLI and MCP. A shared model prevents downstream teams from rebuilding domain logic.
A platform still needs boundaries
A complete stack does not mean one process. Device ingestion, customer data, scoring, cloud configuration and agent access should have explicit trust and failure boundaries.
