Hiring a team or paying by the hour makes the cost of each iteration variable.

| Cost | Variable hours each month | €5,000 a month, fixed |
| Cadence | Releases depend on availability | One release a week |
| Priorities | Negotiated with each request | Shared backlog, ordered by the client |

| Code | Depends on the contract | Client-owned, in the client's repository |
STACK is for clients who already have an MVP in production with DN3 and want to iterate every week without building a team.
First a SPRINT, then STACK.
SPRINT, 14 days. MVP in production for €15,000, €20,000 or €25,000, with code, tests and documentation delivered.
STACK, every week. After the SPRINT, one release a week from a shared backlog for €5,000 a month, paid in advance.
Requirement. STACK is available only to clients who have completed a SPRINT. The feasibility call starts with the SPRINT or, if it is already complete, the backlog.
The initial SPRINT: 14 days, 5 phases, 3 client approvals.
A pipeline of agents writes the code; a DN3 engineer leads it and is accountable for it. The client brings a one-page brief; on day 14 they receive a product in production that they own.
Brief
60-minute feasibility call. Scope is locked in writing.
Spec
Agents produce PRD, data model, API and flows. The client approves.
Build
Parallel agents on a fixed stack. Daily human review.
QA
Automated tests, load tests and a session with five real users.
Release
Deploy on the client's domain, analytics on, handover of repository and docs.
Gate 1, D0. Scope locked. Later requests become a new sprint.
Gate 2, D2. Spec approved by the client. From here the build runs with a daily report.
Gate 3, D13. The client approves the production release.
Every week, throughout the subscription.
- One release to production a week
- Shared backlog, with priorities set by the client
- Weekly summary of what has been released and what comes next
- Maintenance: dependency updates and fixes
- Automated tests updated with every release
- Code always in the client's repository
- Documentation updated with every change
Common questions about STACK.
One or more backlog items sized for a week of work: a small feature, improvements, fixes or technical updates. Larger items are split across several weeks or become a SPRINT+.
The backlog is shared with the client, who sets its order. At the start of the week, the release contents are agreed. At the end of the week, they are released to production.
Yes, on 30 days' notice. The fee is monthly, paid in advance.
It remains yours. The code is in your repository from the first commit, with tests and documentation. DN3's access is revoked on cancellation.
Three questions. Then choose a date and time.
The call starts with the initial SPRINT, or with the backlog if the SPRINT is already complete.
