You describe the outcome; Softermii breaks it into a named, itemised Feature list — each Feature a complete, business-ready capability, built and tested together, not a single task. You prioritise a first-launch scope and get the price up front, attached to that list before a line of code — not guessed from a 20-minute call. One fixed price agreed before we start (Softermii absorbs its own underestimates), working software in week one, and you own every line on payment.

You can validate first. A Softermii APEX Proof — $2,995 — is real working software (never a prototype) for a narrow, clearly defined scope (~15 Features), delivered in 5 working days. Priced in Features, testing an idea costs a fraction of a full build, and you can put it in front of a customer or an investor. If you continue within 30 days, the full Proof fee is credited toward a Build or Scale pack — so you lose nothing for validating first.

Both are settled in the contract. Your code and data run through the engine ephemerally on Anthropic Claude under commercial terms with a zero-retention posture — nothing is stored or reused, and neither Softermii nor its providers train on your code or data (one disclosed legal-retention exception). Transport is TLS 1.3, access is least-privilege, and each customer is isolated. And you own every line outright on payment — assignment, non-assertion, exclusivity and an IP indemnity, no licence back and no dependency on the engine. What we don’t do is badge a certification we don’t hold, so you’ll see no SOC 2, ISO or HIPAA claim here — only what we can stand behind.

A copilot speeds up one engineer typing; it doesn’t own an outcome. Softermii APEX is agentic engineering: work is decomposed and routed to purpose-built agents under a deterministic control layer — not a model — that holds the specification as the single source of truth, and nothing advances until it clears fixed quality gates (spec conformance, static analysis, security, tests, duplication and complexity). Senior specialists own the architecture and every decision that carries real risk. You’re buying a finished, tested, maintainable outcome — not faster typing.

The Softermii APEX engine produces and verifies volume behind fixed quality gates, but named Softermii experts own the architecture, review everything that carries real risk, and are accountable for what you accept. Anything hard escalates to a person with the full failure history. Maintainability is a contracted, measurable standard verified at handover — so an engineer new to the project can build, test and deploy from the delivered documentation alone.

There isn’t one. We absorb our own underestimates, new scope is only ever a new Feature you price and approve, and each release carries a defect warranty — 15 days on Proof, 30 on Build, 60 on Scale. Your protection is the contract, not a claim. And we will tell you when we are not the right fit: if you have a strong in-house team and a stable roadmap, hire; if your scope changes weekly by design, buy hours.
