SAYEMANS is a digital product studio from Eindhoven, the Netherlands. We design and build websites, SaaS platforms and apps for B2B companies and growing startups, from the first sketch to launch day and long after.
Why SAYEMANS
We work with B2B companies, SaaS teams and founders to turn complicated ideas into products that are simple to use. One small team researches, designs, builds and launches it, and stays with you afterwards. No handovers, no templates. Honest work, done with passion.
What we do
Strategy, design, engineering and growth. One team and one process, so nothing gets lost between agencies.
UI/UX, in practice
Twelve fields and five steps, or one tap. Drag the handle to see what a redesign changes.
Illustrative example.
Dutch for expats, built for inburgering.
TaalMeester is a language-learning app built specifically for Dutch. It was not adapted from a generic template. Every exercise, content unit and progression rule is designed around the real challenges learners face on their way to A2, from ordering at a café to registering at the gemeente.

We design and build the product, the website and the landing pages. Mentic brings the right people to them. Clients who need both get one conversation instead of two agencies.

How we work
Six clear phases, weekly demos and one shared roadmap. You always know what is happening, what is next and what it costs.
Workshops, user research and a technical audit. We define goals, users, constraints and success metrics together.
We translate insights into scope: information architecture, user flows and a prioritised backlog with a fixed quote.
Wireframes become polished UI and interactive prototypes, tested with real users before development starts.
Two-week sprints with live demos. Clean, tested code on a staging environment you can click through at any time.
Performance, accessibility and SEO checks, then a zero-downtime launch with analytics and monitoring in place.
We measure, learn and iterate. Care plans keep your product secure while growth sprints push metrics up.
Engagement models
Fixed-scope projects, monthly product subscriptions or hourly consulting. Pick the model that fits your stage.
