What you'd be building

Every capability is a product your team has to own.

Each block has its own build and maintenance cost. The platform foundation is shared across everything that needs engineering—buying Coverbase means someone else owns the whole stack.

Platform foundation (shared)

Shared

The stack every engineering capability quietly depends on.

$76Kbuild$72K/yr run
Cloud environment, networking, and CI/CD deployment pipeline
Identity, access control, roles, and audit logging
Background jobs, queue processing, and scheduling
LLM API integration, prompt orchestration, and cost controls
Secrets management and encryption in transit and at rest
Monitoring, logging, backups, and disaster recovery
Your own SOC 2 program for the tool itself

Quietly serious about risk.

Buy the outcome, not the backlog.

Coverbase owns the whole stack—so your team runs the risk program instead of running the infrastructure.
