Product design agencies in Leipzig compared
The most expensive mistakes in software development don't happen while coding. They happen before it, when the wrong product gets built. These agencies guide the concept phase that comes before actual development, sorted by process, industry, and verified proof of expertise.

What discovery delivers before the first line of code
A discovery phase systematically checks whether a product idea actually solves a real problem, for whom exactly, and how it could be built most economically, before budget flows into development. That includes conversations with potential users, an assessment of the market, early concept sketches, and often a clickable prototype that tests real user reactions without any real code behind it. At best, the result is either a validated, sharpened concept, or the realization that the original idea needs adjusting before you commit a larger budget.
What matters in the discovery phase
Being open to any outcome is what separates a genuine discovery process from mere sales prep for a development project. A good agency is willing to conclude that the original idea should be reworked, instead of confirming every idea it's handed.
Testing with real potential users, rather than just your own team or colleagues, produces far more reliable insights. Ask specifically how these people are found and brought into the process.
A tangible result, such as a tested prototype, clear recommendations, or an honest feasibility assessment, matters more than an elaborate presentation deck. And clarify how the findings from the discovery phase carry over into later development, so the work you invested doesn't go to waste.
What a discovery phase costs
€110 to €180 per hour is typical. A compact discovery phase with a handful of user interviews and a simple prototype costs €8,000 to €20,000 and takes two to four weeks. A more comprehensive validation with several rounds of testing and market analysis runs €20,000 to €50,000.
Typical discovery projects
Validating a new product idea before investing in development. A concept phase for a major extension of an existing product. A clickable prototype for presenting to investors or internal decision-makers. Prioritizing several possible product directions based on real user reactions.

Frequently asked questions
Product design agencies: questions and answers
What does a discovery phase cost?
A compact discovery phase costs €8,000 to €20,000 and takes two to four weeks. A more comprehensive validation with market analysis runs €20,000 to €50,000. Agencies charge €110 to €180 per hour.
Is a discovery phase worth it if I'm already convinced of my idea?
Especially then. A discovery phase costs a fraction of what a failed development effort would cost, and it often surfaces assumptions your own team has stopped questioning. A convincing idea that survives real user testing then moves into development with far more confidence behind it.
What happens if discovery shows the idea doesn't work?
Then it did its job. A failed test in the discovery phase costs a fraction of a failed product after months of development. Often it also reveals how the concept would need to change to work, rather than requiring you to scrap it entirely.
Do I need a separate discovery phase for every project?
Not for every small extension of a proven product. But for new product ideas, larger strategic investments, or cases with real uncertainty about actual user needs, validating up front pays off almost every time.
