Design the metrics, not the screens

We start with the number, then work back to the brief. Senior design and development for funded founders.

Why founders work with us

We find what's broken before we touch the interface

Three situations bring people here

  1. Before the raise
  2. After launch
  3. After a bad agency

“Investors keep asking about the product”

The deck says Series A. The product still reads as a prototype.

“People sign up and then disappear”

Acquisition works. Activation does not.

“After four months of work, we've only got screens”

You are managing five tools instead of building.

What we build

  • The brand

    “The deck, the site, and the product look like three companies”

    One system: positioning, identity, visual language, and the assets your team uses daily

  • The website

    “It still describes the company we were eighteen months ago”

    We rewrite the argument and build it in Framer or any other tool

  • The product

    “Trial conversion sits below the category and nobody can say why”

    We map the activation funnel and redesign the path to first value

  • The app

    “Day 7 retention keeps moving the wrong way”

    We design for the first session, before any feature list. iOS and Android.

Two things sit alongside this work: a design system, for teams about to hire their first internal designer, and full build, for teams with no engineering function or no appetite to coordinate two vendors.

Our best work is under NDA

We built this process for founders with real advantages to protect.

  1. 1

    What we build stays private

    Pre-launch products, internal tools, unannounced features, advantages that only work while nobody has seen them.

    Publishing that would undo the reason founders hire us. Judge us on something else instead.

  2. 2

    On the call

    Bring the product. We tell you what we see in it, live, before you have paid anything. It's a principal on the call, not a salesperson.

  3. 3

    In the first two weeks

    You get a written document mapped against your own analytics, and you keep it whether or not you continue.

  4. 4

    In the terms

    Fixed scope, a defined output every two weeks, and a guarantee on the entry point. It's refundable if it doesn't pay for itself ten times over, in writing.

Every two weeks, the same loop

Established process

The people on your first call do the work. There is no handoff to juniors.

We agree the numbers before anything gets designed

  1. 0

    Runs once

    Clarity Sprint

    Two weeks inside the product, before the loop starts.

    Helps assess the actual state of things, expectations, and market opportunities.

  2. 1

    Scope

    Agreed before anything starts.

    You see the price and the deliverable before a single screen gets designed. Nothing to renegotiate once the sprint starts.

  3. 2

    Build

    Two weeks, one output.

    A finished, implementable design your engineers can start building the day the sprint ends, not a set of directions to argue over.

  4. 3

    Walkthrough

    A recorded video, not a status call.

    Rewatch it, forward it to a co-founder, or send it straight to an investor asking about progress, on their schedule and yours.

  5. 4

    Go to 1st step

    Feedback

    Consolidated in Figma, then back to scope.

    Every comment from your team lands in one file instead of five inboxes. The next scope starts from what this one shipped, not from zero.

The guarantee

Every engagement opens with a two-week Clarity Sprint: we go inside the product, benchmark against your category, and come back with what to fix and what each fix is worth.

Run on its own it is refundable, under the terms you sign beforehand, if it does not surface improvements worth at least ten times its cost in annual impact.

Frequently asked questions

What does this cost?

The Clarity Sprint runs from €5,500 to €8,500, depending on whether it includes a technical architecture review alongside the design audit. What comes after depends on what the Sprint finds, and we quote a specific number rather than a range once we know.

What happens next?

You send the form and hear from us the next morning, Central European Time. The call is half an hour with Ivan or Valeria — a principal, not a salesperson. Bring the product and we will tell you what we see in it, live, before you have paid anything. If it is a fit, the engagement opens with a two-week Clarity Sprint. If it is not, we say so on the call.

Can we talk before we share anything sensitive?

Yes. Tell us when you book and we will send a mutual confidentiality agreement ahead of the call.

How long does a project take?

Work runs in two-week sprints, and how many depends on scope. We will tell you on the call once we understand what you are building.

We have not raised yet. Is it too early?

No. Some of the founders we work with are pre-launch and building toward a raise.

How is this different from a freelancer or an in-house hire?

A freelancer executes the brief you hand them. A first in-house designer takes months to find, costs a salary before shipping anything, and covers one discipline out of the several a product needs. We work out what the brief should be from your own data, then design and build against it, starting in two weeks.

Let's talk about what you're building

“Some of these calls end with us saying you don't need us yet. That is a real outcome, and thirty minutes is a cheap way to find out.”

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

The product, the problem, and what you've already tried

No deck, no obligation. One conversation, confidential if you want it to be.
