Building Interfaces That Actually Make Sense

We started Manthex because we kept seeing the same problem. Talented developers creating products users couldn't understand.

Since 2019, we've worked with businesses across the UK to fix that disconnect. Our approach combines research with practical design thinking to create digital experiences people can use without thinking twice.

How We Got Here

Back in 2019, our founder was debugging user complaints for the third time that week. The code was perfect. But users kept abandoning the checkout process at the same spot.

Turned out the button placement made no sense to actual humans. That realisation sparked something. What if we flipped the process and started with how people think instead of how systems work?

We pulled together a small team in Wolverhampton and started testing that idea. Six years later, we're still at it. The problems got more complex but the principle stayed simple: design for humans first, then figure out the tech.

What Drives Our Work

Research Over Assumptions

We test designs with real users before writing a single line of code. Saves months of expensive revisions later.

Honest Feedback

If your idea won't work for users, we'll tell you straight. Then we'll help you find something that will.

Practical Solutions

We design within your constraints. Budget limits, technical debt, tight deadlines. We work with what you've got.

Our Process

Most agencies start with pretty mockups. We start by watching people struggle with your current setup. That tells us more than any stakeholder meeting ever could.

From there, we prototype fast and test faster. You'll see working designs within weeks, not months. And we keep refining based on actual user behaviour until it clicks.

  • User research sessions that uncover real friction points
  • Rapid prototyping to test ideas before commitment
  • Iterative design based on measurable user behaviour
  • Implementation support that works with your developers
