Clarity Sprint · 14 days · €5,500 to €8,500

“Is this worth paying for now?”

The Clarity Sprint is a two-week product design audit for funded startups. It costs €5,500 to €8,500, puts an ARR figure on every fix, and the fee comes back under written terms if it does not surface ten times its cost.

Every design proposal you have read answers the wrong question

You asked what the work is worth. The proposal told you what it contains: twelve screens, six weeks, a designer and a half. You still had to guess whether any of it would move the number the board will ask about.

That is the old way of buying design: priced by the screen, judged by someone’s taste how it looks, measured by nobody. It is why so many founders have a folder of nice finished screens and the same trial-to-paid rate they had last year.

The Sprint starts from the other end. First the number, then the fixes, then a price on each one. You decide what to buy after you have seen what it is worth.

What two weeks inside your product produces

On day 14 you get four things

  • Your metric against its benchmark

    Trial-to-paid, activation, onboarding completion or retention, measured from your own analytics and compared with a published category benchmark. The source is named, so you can check it.

  • Every fix ranked, with an ARR figure on each

    A table of specific changes. Each one has an effort estimate and a conservative 12-month impact figure, so the cheap, high-value fixes rise to the top on their own.

  • The next scope, ready to approve

    The flows, screens or pages the findings justify, described closely enough that work could start the following Monday.

  • A report and a recorded walkthrough

    One of our principals records the walkthrough. Send it to your co-founder, your board, or the investor who keeps asking about the product.

How the numbers are built

Every figure comes from one formula, and the report shows each step so you can rerun it with a phone calculator

Annual impact = (target rate − current rate) × monthly volume × value per unit × 12

We never plan for closing the whole gap to the benchmark. The target closes 30 to 50% of it, because a number you can defend in a board meeting is worth more than one that looks good on a slide.

Illustrative inputs, so swap in your own:

trials a month, $ ACV

Trial-to-paid at %, category benchmark %

A target that closes 30 to 50% of the gap: 11.5% to 12.5%

1.5 to 2.5 points × 400 × $6,000 × 12 = $432,000 to $720,000 in new ARR a year

Three rules hold for every number in the report. The current rate comes from your analytics, never an estimate. Volume and value per unit are your own figures or your public pricing. Benchmarks come from published research, named in the report.

The report, section by section

These are the headings of every Sprint report. What goes under them is always yours alone.

  1. Summary

    Baseline, benchmark, the total conservative upside of the top recommendations, and the one change that matters most.

  2. Audit

    Findings rated Critical, Major or Minor, at screen or page level.

  3. Competitive benchmarking

    The benchmark table and what comparable products do at the same step.

  4. User signal synthesis

    Feedback themes ranked by how often they come up. For SaaS and mobile, a jobs-to-be-done map.

  5. Recommendation matrix

    Every change, its effort, its conservative impact and its priority.

  6. Next-sprint scope

    The specific scope the findings justify.

  7. Methodology and data sources

    Every formula, input, source and assumption, complete enough to reproduce every number.

The guarantee, in writing

The Clarity Sprint carries a written guarantee: if it does not surface at least ten times its fee in annual impact, you get the fee back. Time-boxed and fee-capped, full terms in the agreement.

For a €5,500 Sprint, the bar is €55,000 in conservative annual impact. For €8,500, it is €85,000.

The terms, as you sign them:

  • We measure the conservative 12-month figures in section 5 of the report, using the method in section 7.
  • We measure them when the report is delivered. This guarantees the Sprint’s own arithmetic. It does not promise revenue after you implement.
  • You give us read-only analytics access before the Sprint starts, and your input figures are accurate as far as you know.
  • If you dispute a figure, you get the calculation workbook within 5 business days. A real error that drops the total below 10× triggers the refund.
  • The refund is the full fee, paid within 10 business days of your written request. You keep the report.

The guarantee applies when the Sprint runs on its own, under the Clarity Sprint Agreement.

Price

€5,500 to €6,500 for a design audit. €8,500 with a technical architecture review alongside it.

The agreement carries one number, not a range, and the fee is invoiced in advance on signature. If you continue within 90 days, the fee is credited in full and the report becomes your first sprint, so you never pay for discovery twice.

You can treat the Clarity Sprint as our onboarding in just two weeks with 360° view.

Before you book: three questions

  1. Do you know this month’s number for the metric your round depends on, or only the one in your last deck?

  2. Can you give us read-only access to your analytics before the Sprint starts?

  3. Is the roadmap about to change under the product you want audited?

    If it is, hold the budget. Audit the product you will still be selling in three months, not the one you are about to replace.

How it runs, from call to report

  1. A 30-minute call

    Bring the product and one number. A principal tells you what they see in it, live, before you have paid anything.

  2. The agreement

    One price, the metric we will measure, the benchmark source and the start date, all in writing.

  3. Fourteen days inside the product

    Analytics, flows, competitors, user signals.

  4. The report and the walkthrough

    Then you decide what happens next, with the numbers in front of you.

Where it can lead

The report scopes what comes next, and there are three ways to continue. GENESIS, for Pre-Seed and Seed teams, is product design that makes the product tell the story the round needs. EVOLUTION, for Series A and B teams, is a product overhaul against the metric the Sprint priced. Strategic Partner is post-launch design on a monthly retainer, with the scope agreed in writing each month.

Or you stop, keep the report and hand it to your own team. That is a good outcome too.

Who does the work

The two principals on your first call run the Sprint and record the walkthrough. Nobody junior picks it up halfway.

  • Valeria Shumska

    Co-founder, Head of Product Strategy and Design

    MSc in computer engineering, 10+ years in systems and product design.

  • Ivan Kraskov

    Co-founder, Design and Communication Principal

    20+ years designing for startups and scale-ups, across product design, UX strategy and front-end.

We take three projects at a time, because the principals do the work themselves. A mutual NDA comes before any sensitive conversation, and here is why we work that way.

FAQ

What does a product design audit cost?

The Clarity Sprint costs €5,500 to €6,500 as a design audit, or €8,500 with a technical architecture review. The price is fixed before work starts and does not move once it does.

What if the Sprint finds nothing worth fixing?

Then the report says so. If the conservative figures fall short of ten times the fee, the guarantee applies and the fee comes back. You keep the report either way.

What do you need from us?

Read-only access to your analytics (GA4, Mixpanel, Amplitude, Hotjar, Firebase or similar), your current volume and revenue figures, and one person on your side to review the findings.

What if we cannot share analytics access?

We still run the audit with heuristic and qualitative methods. The guarantee then does not cover the revenue figures, and we confirm that with you in writing before the Sprint starts.

Can we hand the report to another studio to implement?

Your own team can act on it freely. If a third party is hired to implement the specific recommendations and you do not continue with us, a licensing fee applies under the agreement. We would rather you read that here than discover it later.

How fast can it start?

Once the agreement is signed, the invoice has cleared and analytics access is in place. Tell us your deadline on the call and we will say honestly whether two weeks fits before it.

Let’s put a number on it

Bring one metric you need to move before your next raise. We will tell you whether design can move it, and roughly what that would take.

Tell us about your project and the number you’re trying to move. You don’t need a finished brief, just a specific problem.

You talk to Ivan or Valeria, not a salesperson. Write today and you hear back the next morning, Central European Time.
