Product Strategy & Discovery

We help you find out what is worth building before you build it, using research, prototypes, and a clear roadmap, so your first release solves a real problem for real people.

Overview

Many products fail because no one needed them, not because they were badly built. Teams commit to a scope based on the loudest opinion in the room, spend months on it, and find out too late. Discovery replaces that guess with evidence: you talk to users, test ideas cheaply, and decide what to build first with clear reasons you can show to others.

Evidence before commitment
Interviews, data, and prototype tests show whether an idea is worth building before you spend on it.
A scope you can defend
Every item on the roadmap is tied to a user need and a business goal, so priorities are easy to explain.
A plan the whole team shares
Product, design, engineering, and leadership leave with the same picture of what comes first and why.

What discovery covers

The work that takes you from a rough idea to a plan you can fund and defend.

User research
Interviews, surveys, and observation to understand what people are trying to do and where they get stuck.
Opportunity and market review
A look at alternatives, competitors, and demand, to find where your product can be different.
Prototyping and testing
Clickable prototypes tested with real users, so you learn from them before writing production code.
Product vision and roadmap
A clear statement of what the product is for, and a phased roadmap with the reasons behind the order.
Measures and metrics
A small set of measures that show whether the product is working, and the tracking needed to see them.
Costing and business case
Estimates of build and running costs, and a case for investment that finance and leadership can review.

Questions we answer

The questions every product team has to answer, and the evidence we gather to answer them.

  • Who is this for, and what do they need?

    How we find out

    Interviews with your target users and a review of any data you already have on how they behave today.

    What you get

    A clear description of your users and their top problems, in their words.

  • Which idea should we pursue first?

    How we find out

    We score ideas on user value, business value, effort, and risk, and test the riskiest assumption first.

    What you get

    A ranked list with a recommended starting point.

  • Will people actually use it?

    How we find out

    A prototype tested with real users, watching what they do rather than only what they say.

    What you get

    Test findings, with what to change and what to keep.

  • What goes in the first release?

    How we find out

    We draw the line between what is essential and what can wait, and agree it with you and your team.

    What you get

    A scoped first release and a phased roadmap behind it.

  • What will it cost, and what will it return?

    How we find out

    Build and running estimates, with the measures that show whether the product is paying off.

    What you get

    A business case with ranges, not a single optimistic number.

Approach

Short, focused steps that each reduce a specific risk, so you can stop early if the idea does not hold up.

  1. Phase 1

    1 week

    Frame

    • Agree goals, constraints, and what you already know
    • List assumptions and rank them by risk
    • Plan who to talk to and what to test

    You receive

    Discovery plan and a ranked list of assumptions.

  2. Phase 2

    2 to 3 weeks

    Research

    • Interview users and the people who support them
    • Review data, feedback, and competing products
    • Map the current journey and its pain points

    You receive

    Research findings and a map of the user journey.

  3. Phase 3

    2 to 3 weeks

    Prototype and test

    • Design a clickable prototype of the main idea
    • Test with five to eight users and improve it twice
    • Check feasibility with a senior engineer

    You receive

    A tested prototype and a list of what users valued most.

  4. Phase 4

    1 week

    Decide

    • Agree the first release and the roadmap behind it
    • Estimate cost and set the measures of success
    • Present the recommendation to your leaders

    You receive

    Product vision, roadmap, estimate, and business case.

Engagement models

A short sprint to test one idea, a full discovery, or ongoing product coaching. Choose what fits your stage.

Idea check

Teams with one idea who want to know quickly if it holds up.

2 weeks

  • Assumption review
  • Five user interviews
  • A simple prototype test
  • Go, change, or stop advice

Full discovery

Teams planning a new product or a major change and needing a funded plan.

4 to 8 weeks

  • Research and prototype testing
  • Roadmap and first release scope
  • Cost estimate and business case
  • Leadership presentation

Product coaching

Teams that run their own product work and want a strategist beside them.

Monthly, rolling

  • Regular reviews with your product lead
  • Research support
  • Roadmap and metrics review
  • Scale up or down with notice

Ways of working and tools

How we make sure decisions rest on evidence, and the tools we use to gather it.

How we keep it honest

Evidence, not opinion
Every recommendation points back to something we saw, heard, or measured, and we say so when evidence is thin.
Research done properly
Participants give consent, their details are protected, and recordings are deleted when the work ends.
Your users, your findings
Notes, recordings, and prototypes are handed to you in full when the work is done.
Open to challenge
Assumptions and trade-offs are written down, so anyone on your team can question them.
Willing to say stop
If the evidence says the idea will not work, we tell you, and that is a useful result.

Tools we use

Research
Zoom, Dovetail, UserTesting, Typeform, Maze
Prototyping and design
Figma, FigJam, Framer, Miro
Analytics
PostHog, Amplitude, Mixpanel, Google Analytics, Hotjar
Planning
Linear, Jira, Productboard, Notion, Aha!
Estimation and business case
Spreadsheet models, scenario ranges, and cost breakdowns your finance team can review
Reporting
Short written findings, a roadmap, and a presentation for your leaders

We use whatever your team already uses for planning and feedback, so findings stay with you.

Frequently asked questions

We already know what we want to build. Do we need discovery?

A short idea check is often enough. It takes two weeks and can save months if one key assumption turns out wrong.

Can you recruit users to talk to?

Yes. We use your customers where we can, and recruit from outside when we need people you do not know yet.

What do we have at the end?

A tested prototype, a roadmap, a first release scope, a cost estimate, and a business case you can take to leadership.

Do we have to work with you for the build afterwards?

No. Everything is handed over in full and can be used by your own team or any other supplier.

What if discovery says do not build it?

Then you have spent a few weeks, not a year. That is one of the most valuable results a discovery can give.
