Non-technical founders face one funding question: pay in full, or find a build partner. Upfront costs EUR 15.000 to EUR 80.000 cash; you keep 100 %. Build-partner cuts cash to EUR 5.000 to EUR 30.000 for 5-15 % equity or 10-20 % revenue share. Neither is universally better.
What “build partner” actually means
A studio that takes reduced cash in exchange for a stake in the product’s success. Cash covers direct costs (salaries, infra, tools); equity or revenue share is the upside, aligned with growth. It is not a free agency, not a technical co-founder (a team, not an individual, with smaller stake), and not an investor (work, not capital).
How the models compare
| Factor | Pay upfront | Build partner |
|---|---|---|
| Cash for v1 | EUR 15.000 - 80.000 | EUR 5.000 - 30.000 |
| Your ownership | 100 % | 85-95 % or 100 % minus rev-share |
| Partner incentive | Deliver on scope | Deliver a successful product |
| Speed to start | Immediate | Slower (alignment required) |
| Ongoing relationship | Ends at delivery | Long-term |
| Best for | Clear scope, full budget | Strong idea, partial budget |
When pay-upfront is the right call
You have the budget without stretching runway. Scope is well defined after a Discovery sprint. You want clean ownership without cap table complications. The idea is proven - customers exist, you need execution. See custom software cost in Croatia.
When a build partner makes sense
The idea is strong but the budget is tight (EUR 10.000 to EUR 20.000, not EUR 50.000). You bring domain expertise and distribution: market knowledge, access to first customers. You want long-term alignment - a partner with 10 % cares about post-launch success differently than a paid vendor. The product needs validation, and pivots are likely.
Typical deal structures
Cash + equity. EUR 10.000 to EUR 25.000 cash, partner gets 5-15 % equity vesting over 2-4 years. Unvested shares return if partnership ends early. Cleanest for venture-track ideas.
Cash + revenue share. EUR 5.000 to EUR 20.000 cash, partner gets 10-20 % of net revenue for 3-5 years, capped at 2-3x the work value. Works for profitable businesses that may never raise capital.
Red flags
Partner wanting more than 20 % equity for v1 - that is co-founder territory. No vesting - they can walk after the first sprint with full equity. No defined scope. From the partner’s side: founder has no distribution, treats the partner like a free agency, or refuses a written agreement.
Frequently Asked Questions
Can I buy back the partner’s equity later? Yes, if the agreement has a buyback clause tied to revenue multiples or a fixed formula. Always negotiate this before signing.
What if the product fails? Both sides lose - founder loses cash, partner loses hours. Equity in a failed product is worth zero. That is exactly why the model aligns incentives.
How do I find a build partner? Start with agencies that explicitly offer this model. Most are strictly fee-for-service. Ask: “Do you take projects on a build-partner basis?” Then ask to see a sample deal structure.
Does EU funding work with this model? The cash portion may qualify for reimbursement; the equity portion does not. See EU funds for SME digitalisation.
