Draft — pending legal review. Stratum is invite-only, and every firm signs a service agreement before it starts. These are the terms for this website and the plain-language summary of how we work; the signed agreement governs the service.
The pages, copy and sample screens on this site are Stratum’s. The sample data is a fictional firm. The leak calculator is an estimate built from your inputs, not a promise of results.
Firms use Stratum under a written agreement that covers pricing, support, data ownership and continuity. Your firm’s data is yours; you can export it at any time. We keep the system running, back it up nightly, and tell you plainly what controls are in place.
Stratum is built and run by Caleb Christen, PE, inside a working civil engineering firm. The legal entity will be named here once it is formed.
