Prototype sprint

Product engineering
From prototype to platform.
We build SaaS products and platforms with sign-in, roles, tenants and billing, hosted on servers in the EU. The code lives in your repository from day one.
Typical starting point
01
“An idea or an internal tool is meant to become a product customers pay for.”
02
“An existing piece of software has grown, but roles, tenants and billing are missing.”
03
“A former service provider has the code; you do not.”
What we build
Prototype
Clickable, with real content, before actual development begins.
Sign-in and roles
Who may see and change what, cleanly separated down to the database.
Tenants
Several customers on one platform, without data mixing.
Billing
Subscriptions, plans and invoices with Stripe.
Audit log
Traceable who changed what and when, from day one.
Releases
Staging and live, with release notes for every version.
How it runs
Step 1
Prototype sprint
We clarify scope and workflows and build a clickable prototype.
Step 2
Fixed price
On the basis of the prototype you receive a fixed price for version 1.
Step 3
Build in stages
Regular intermediate states on staging; you test along.
Step 4
Launch and operations
Go-live, then further development or handover to your team.
What you hold in your hands at the end
- Code in your repository, from day one
- Staging and live environment
- Documentation for development and operations
- All access in your name
- 30 days of bug fixing after acceptance
