Through focused sprints, we work side by side with founders to turn promising ideas into tested propositions, stronger decisions, and faster traction.

What you sign up for
No surprises or hidden terms here. There are three ways to sprint, you just pick the one that fits your state.
Model 01 · Fee-Based
You pay for the sprint. You keep the company.
What WIP brings
The full co-build team — product, design, tech, GTM. Sprint architecture and methodology. Behaviour change measurement at close. The network.
What you bring
Sprint fee (structured in tranches tied to phase gates, not upfront). Active founder commitment across all 100 days. A problem worth solving.
Best for founders who have access to capital and want to retain full ownership from day one.

Model 02 · Sweat Equity
WIP co-invests effort. We take a small stake.
What WIP brings
The problem, the domain knowledge, and the founder commitment. No sprint fee. The equity stake is the agreement.
What you bring
Everything in the fee model plus WIP's stake means we are aligned with you for the long term and not just one for one sprint.
Best for founders solving an urgent problem with limited capital and want a co-builder with skin in the game.

Model 03 · Impact Trading
You create the impact. We bring the expertise & capital.
What WIP brings
The domain expertise. The community. The user relationships that no outsider can build. Your access to the problem is the asset.
What you bring
Everything in the other models plus capital partners who fund the sprint because the impact case is strong enough to back.
Best for domain experts who are not traditional founders but have direct access to the problem and community.

All models end with a real validation of on ground behavior change.

What stage is your innovation in?
Four starting points. Same sprint principle. Different first conversations.
What a typical sprint looks like
What to expect from our intense time bound validation formula.
Locate
We find the real constraint: user behaviour, field context, operating friction, and the outcome worth measuring.
Decision gate
Are we solving a problem that matters enough to build?
Shape
WIP brings the expertise you do not have yet - product, design, engineering, research, and domain knowledge; through our partner network. You make the decisions. We build what needs to be tested.
Decision gate
Are we still solving the right problem?
Confront
You put it in front of real users in real context. WIP sets up feedback loops and impact measurement so you capture what actually matters, not just opinions.
Decision gate
Is it shifting behaviour in the real world?
Resolve
What changed? You leave with evidence you can take to investors, partners, or your next sprint.
Decision gate
What worked, what failed, and what happens next?
This is an intense time bound commitment. The constraints are in the model and thats what makes the outcomes real and measurable. Founders who cannot give at least a 100 days of commitment should not apply.
What a typical sprint looks like
What to expect from our intense time bound validation formula.
Resolve
We turn the learning into a decision of what should be built or tested next.
Decision gate
What is the evidence telling us to do next?
Confront
We put the artefact against real users to see validation evidence.
Decision gate
What changed when it met the real world?
Shape
We make the assumptions testable by building the smallest artefact.
Decision gate
What needs to be made real to test?
Locate
We strip away the noise to find the uncertainty that matters most

What must be true for it to move forward?

You won't build alone
When you sprint with WIP, you plug into a network that has been building in your domain for years. No generalists. Domain experts who have been building in your specific problem space.
Expert Network
Design, technology, research, strategy, operations, and venture-building partners.
Institutional & Impact Network
Organisations led by their domains are ready to help build your idea into impact.
The goal is simple: move faster from problem to proof without losing rigour.

Amsterdam-based. Globally active.
WIP is headquartered in Amsterdam. We sprint remotely and in-person. We have worked with founders from across Europe, Africa, South Asia, and North America.
We do not filter by geography. We filter by commitment and problem quality.
Questions founders ask before they build with WIP.
Start your application
Every question will help you refine your idea. And we respect your time so check your inbox for a response within 48 hours.
By submitting this form you are starting a conversation, not signing anything. WIP will respond within 48 hours with a short intake call invitation or a follow-up question.
Our sprints run because of partners who believe impact deserves infrastructure
WIP does not fund sprints from a single source. Capital partners like banks, foundations, impact funds, and HNWs who back the sprint model because they believe in what it produces. When you sprint with WIP, you are not funding a small studio from a personal account. You are plugging into an infrastructure that was built before you arrived.
