Jeroen Riemens

Product Designer & Advisor

Hoi! I'm Jeroen—a Dutch digital product designer and advisor. I have been hired by 100+ start-ups and product teams to help them ship the right things, fast. The products I worked on are used by over 5 million people worldwide. When I'm not designing I like to ride bikes, make music, travel and eat sushi 🍣

I partner with founders and product teams to ship the right things, fast.

For 1 to 4 days a week, I join teams in a hybrid manner — combining in-person strategic work (like brainstorms and team alignment) with remote focus work (like prototyping, user research and crafting production designs).

Shaped by fifteen years of experience, I use a simple yet effective approach to accelerate shipping velocity in startups and product teams:

01 Strategy
02 Validation
03 Production
What do we build next?How do we make it right?How do we ship it fast?
We prioritize and ideate based on user and market research, usually in a recurring founder/PO call or in a brainstorm session.I create small, interactive prototypes, test internally and with users, and iterate. This ensures we solve the difficult problems first.Leveraging my technical background, I have regular sessions with developers to provide them with what they need and get it shipped, fast.

I work with founders and product owners as:

  1. The sole designer in a startup, partnering with the founder on product strategy. I turn ideas into tangible prototypes, validate them with users, and align with developers to ship features fast—accelerating the path to product-market fit.
  2. A member of a small design team, focusing on product strategy, early-stage prototyping/validation, and optimizing development handover—typically working alongside designers who refine prototypes into production-ready designs.
  3. A product advisor, providing strategic guidance through weekly calls or ongoing support. I help shape product direction, refine priorities, and improve design-development workflows without being embedded in the team full-time.

If this sounds like a fit, let's start with a quick call or a small pilot to see how we can work together. No commitment—just exploring if it's a good match.
