I'm Craig, founder of Fluke Design.

Based in Haarlem, NL. Let's chat over a coffee ☕️

I've been designing complex products from the ground up for over 10 years, most often in the earliest stages of a company's life. When priorities are still shifting and you're learning who your customers are every day.

I work as a partner to founders and founding teams, blending real product thinking with high quality hands-on design execution. Utilizing the tools of the day to maximize speed and efficiency.

When we work together, you're working directly with me, not a team or account manager. I ramp up fast, get invested in your success, and aim to contribute as a full member of the team.

Who I partner best with

Good fit if…

  • +You're an engineering-led team: strong technical execution, no one in-house owns product design
  • +You're still early, but product progress is lagging behind the business
  • +Your product is young, but it's functional, and you know the UX is not up to your standards
  • +You don't have a senior designer owning the system yet. Or, you're looking, but feel how hard it is to hire for this role.
  • +Your product is starting to get into your users' hands, and you want to give them confidence in your solution
  • +Your engineers are shipping with AI tooling, but the product is drifting with every push. Inconsistent patterns, decisions nobody owns, things reused in the wrong place

Not a fit if…

  • ×A visual uplift is your primary motivation. I'm not a branding or graphic design shop
  • ×You're still at the idea stage, no product, no team building it yet
  • ×You prefer a design agency that works with big brands or later-stage companies
  • ×Your product value is solely in the engine, not the experience

Questions founders usually ask.

How is this different from hiring a full-time designer?+

Hiring the right full-time product designer is hard: most candidates haven't worked in the chaos of an early-stage startup, and a bad hire costs months. I bring startup-tested judgment and start quickly. When you do hire, they walk into a working design system, clear patterns, and product decisions they can build on, so they're effective from their first week.

What's the difference between the three offerings?+

Diagnostic is a one-time expert assessment. Strategic Advisor is ongoing support, either alongside your in-house designer or through regular working sessions with your team. Embedded is a full hands-on design partnership, working as part of your team.

Do you do visual or branding design?+

No. I focus on product usability, interaction design, and the underlying system, not visual identity or brand design.

Do you work with companies outside Europe?+

I'm focused on working with European founders and supporting the ecosystem where I live, which also means I can kick off engagements on-site with your team. However I'm always happy to connect with founders building compelling products from anywhere in the world.

Do you only work with technical founders?+

No, I also work well with domain-expert founders: people who deeply understand the problem or industry but not the UX/product layer.

What if we already have a designer?+

That's fine, I'm happy to support them as part of the engagement. I have years of experience managing design teams — product designers, content designers, researchers, PMs, even engineers — and enjoy contributing through coaching, mentorship, and design/product direction, not just hands-on execution.

How fast can you start?+

That depends on current availability, which changes often. Best way to find out is to book a call: we can talk timing alongside what you're looking for.

Why don't you over-invest in research cycles or heavy process?+

I believe in a ship-to-learn mentality. Design systems and foundational patterns matter, and I invest in them early, but I don't believe in over-researching before you've shipped and learned from real usage. A few deliberate foundational decisions save months of rework later; endless research cycles just delay learning what actually works.

Let's talk about
what you're building.

Where you're at today, where you want it to go, and how I can help you reach your next major milestone. I'll get back to you within one working day.
