Fixed-price software. An MVP in 14 days, a price set before we start.
A public price list, four lines, no quotes: MVP at €15k, €20k or €25k depending on the flows, extra sprints at €5k, continuous evolution at €5k a month.

Whoever buys software by the hour doesn't know what they'll pay until the end.
| Variable | Hourly vendor | DN3 |
|---|---|---|
| Price | Variable estimate, known only after delivery | Public price list, fixed from day 0 |
| Time to first release | Months, sequential phases | 14 days |
| Scope | Negotiated during the project | Locked in writing on day 0 |
| Code ownership | Varies, often at the end of the project | The client's from the first commit |
| Vendor incentive | More hours, more revenue | Deliver by day 14 |
With a fixed price list and a release in two weeks, the cost of testing an idea with real users is known before starting and does not change during the work.
14 days, 5 phases, 3 client approvals.
A pipeline of agents writes the code; a senior 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
45-minute scoping 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 review by a senior engineer.
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.
Standard sprint delivery.
- Web or mobile app in production on the client's domain
- Backend, database, authentication and payments already wired
- Client-owned repository, with documentation and deploy pipeline
- Product analytics set up from the first user
- Test report with five real users and first metrics
- Backlog of the next three iterations, with estimates
- No lock-in: the client can continue with DN3, with their own team or alone
- One recorded hour of handover with the sprint's lead engineer
The price list. Four lines, the same for everyone.
Full MVP in 14 days. The price depends on a single variable, the number of core flows:
Set on the scoping call, it never changes.
- 50% at kickoff, 50% at release
- 1 dedicated senior engineer and agent pipeline
- Standard delivery listed above
SPRINT+: one extra feature in 7 days, fixed price. STACK: maintenance and continuous evolution in small steps, one release a week on a shared backlog.
- Paid upfront
- STACK: 30 days' notice to cancel
- Reserved for clients who completed a SPRINT
For 3-4 startups a year selected by DN3: SPRINT at a reduced price in exchange for a minority stake.
- Full-time founder with an identified market
- Standard term sheet
- Access to the DN3 network
The day-14 rule. If on day 14 the product is not in production with the scope locked on day 0, the remaining 50% is not owed* and DN3 completes the work at its own expense. Scope is written and signed by both parties on day 0.
Conditions
* The rule does not apply when the delay is not attributable to DN3: scope-change requests during the sprint, client approvals or answers not delivered within the gate timelines, or outages of third-party services outside DN3's control, including AI service providers, cloud platforms and network infrastructure. In such cases the remaining 50% remains due under the contract terms.
Good fits and poor fits.
Good fit for
- Founders with a defined idea to validate with real users
- SMEs or corporates wanting to test a digital service with set budget and timing
- Existing products needing a module or a new vertical in two weeks
- Clients able to respond to each gate within 24 hours
Not a fit for
- Projects requiring a complete product at first release: an MVP covers only core flows
- Projects requiring a large team managed by the hour
- Projects whose scope can't be locked on day 0
- Systems where each release needs compliance audits longer than the sprint
Questions we hear on scoping calls.
Any product that fits on one page and has three to five core flows: marketplaces, vertical SaaS, service apps, B2B portals, internal tools. Hardware, firmware and systems requiring certification before release are excluded.
A pipeline of coding agents, led and checked by a senior engineer who is accountable for it. The engineer reviews every day and approves the release. Code is delivered with tests and documentation.
45 minutes for the scoping call, half a day to approve the spec, about 15 minutes a day for the report, one hour on day 13 to approve the release. Under two working days across two weeks.
The client, from the first commit. The repository is created in the client's account and DN3 joins as a collaborator. Access can be revoked on day 14.
If on day 14 the product is not in production with the day-0 scope, the balance is not owed. If the product works but the market doesn't respond, the cost of the test is capped at the sprint price.
With an hourly model the vendor earns more the longer the project runs. With a fixed price, DN3's margin depends on delivering by day 14.
Three questions. Then pick a date and time.
