What is user research?
Understand user needs and uncover product opportunities
User research means studying the people who use your product: their goals, their context and the problems they work around today. In product discovery it comes before the solution and shows which problems are worth solving. Interviews and diary studies are qualitative, so every report makes clear which findings are observed, which are interpretation and which need further validation.
Unmet needs
What people struggle with today and what they work around.
Context and motivation
Why people choose, hesitate or drop out in their real situation.
Opportunities worth solving
Which problems matter most to users and to your goals.
When is user research right for your product?
A good fit if
You are planning a new product, feature or market and want to know what people actually need.
Customer feedback is scattered and nobody sees the full journey.
Analytics show what users do, but not why.
The roadmap rests on assumptions nobody has checked with users.
Not the right fit if
You already have a prototype and want to know if it works. That’s usability testing.
You need to measure how a change performs. That’s an A/B test.
The decision is already made and you only need approval.
You need market sizing or sales forecasts.
Already have something people can try? Usability testing shows whether it works for them.
What I research
What can discovery research help you understand?
Qualitative and quantitative methods, chosen for the product decision at hand, in German, English or Polish.
In-depth user interviews
Needs and motivations
What people are trying to achieve, what drives their decisions and what makes them hesitate. My background in psychology shapes how I ask and interpret.
Diary studies
Behavior over time
How people use a product in their real context over days or weeks, including the moments interviews miss.
Stakeholder interviews & journey mapping
Customer journeys and touchpoints
Where the experience works across channels and where it breaks, mapped from research instead of internal assumptions.
Card sorting
Navigation and information architecture
How people group and look for information and which structure matches their mental model.
User surveys
Patterns at scale
How widespread a need or problem is, measured with surveys designed to complement the interviews.
Measurement framework
Experience measurement
Which signals show whether the experience improves over time, turned into recurring measurement your team can track.
How the user research process works
STEP 1
Frame the decision
We define the product decision, the critical assumptions and the research questions together with your team.
STEP 2
Design the study and recruit
I choose the right mix of methods, define participant criteria, write the research plan and plan recruitment with you.
STEP 3
Run the research
I moderate interviews, run diary studies and field surveys remotely in German, English or Polish.
STEP 4
Analyze and synthesize
I connect what people say with what they do and turn the evidence into patterns, needs and opportunity areas, with uncertainty clearly documented.
STEP 5
Turn findings into decisions
We review the evidence together, prioritize opportunities and agree on the next research or product steps.
What you’ll receive
Research deliverables your team can plan with: every insight is linked to the evidence behind it and to the product decision it informs.

Ready to understand what your users need?
User research cost, timeline and scope
Every project starts with a clear question and a defined scope. Before we start, you receive a proposal with the approach, deliverables, timeline and investment.
What drives the cost
The methods, the number of participants, how specific your target audience is and the depth of analysis. Recruitment and participant incentives are billed separately.
What you need
A product question worth answering, access to your users or a research panel and time for a live readout with your team.
How long it takes
A research sprint takes 2 to 3 weeks, depending on recruitment. Broader studies run over several weeks or rounds.
Prices are net; VAT is added based on your country and tax status.
