Now taking on founding clients in KigaliFounding rate

Find the rust
before your users do.

Independent audits for apps, websites and platforms. We test what your users experience and what your system actually does, on the phones and networks they really use. Every problem comes back with proof, a severity and a specific fix.

  • Five lenses in every audit
  • Evidence behind every finding
  • Checked against WCAG 2.2 AA
  • Re-check included
Sample audit report: mobile banking app

Evidence

Screen-reader recording: the amount field has no label, so the form can’t be submitted.

Recommended fix

Add a visible label tied to the field, and announce validation errors as they appear.

Built for products people can’t afford to see fail.

What we inspect

Five lenses, one inspection

Most audits stop at what’s on the screen. Ours also tests the rules underneath, the habits of the people using it, and the conditions it has to survive. All five lenses, in every audit.

Can people finish what they came to do?

We walk through your most important journeys the way your customers would, and record every point where they hesitate, guess or give up.

  • Key journeys completed without help
  • Labels, steps and errors that make sense
  • Dead ends and loops found and traced

Inside the
inspection bay

Your product goes up on the lift. Each lens has its own instrument, and every reading feeds the same report.

Why Bayrust

Proof, not opinions

What makes a Bayrust report something your team acts on the same week, instead of a document that sits in a folder.

Every finding is a tagged part

An ID, a lens, a severity, replayable evidence and a specific fix. Nothing vague, nothing to argue about.

Tested where your users are

Low-cost Android phones, slow and dropping networks, shared devices, mobile money and USSD. The conditions your product actually lives in.

Written for two readers

Engineers get reproduction steps, delivered straight into Jira, GitHub, Trello or a spreadsheet. Leaders get one page on what to fund first.

Independent by design

We don’t build software or sell tools, so there’s no follow-on contract to protect. The report says what’s true, not what’s convenient.

The re-check is included

Once your team ships the fixes, we inspect every one again and confirm the rust is really gone, with fresh evidence.

When teams call us

You don’t need a crisis to need an audit

The teams closest to a product are the last to see its rust. An outside inspection is worth it at four moments.

Before a launch

The cheapest moment to find rust is before your customers do. We can inspect prototypes, staging and beta builds.

Before you accept a vendor’s delivery

An independent check that what you paid for actually works, before the final invoice is signed.

When customers complain and nobody knows why

Support calls are rising, completion is falling, and the team can’t agree on the cause. We find it.

Once a year, as a health check

Products drift as features pile up. A yearly inspection catches the rust before it spreads.

Who inspects your product

Led by a product designer, not a sales team

Bayrust is led by Aston Guevara Seka, who has spent eight years designing digital products and reviewing what development teams actually ship. Every audit is done by people who have built products themselves, so every fix we recommend is one a real team can ship.

  • Senior UX designer at a Nordic EdTech company, working on its design system and reviewing the quality of what teams ship
  • Former lead product designer of a vehicle telematics platform
  • Product designer since 2018, across food tech, software and education
  • BSc (Hons) Entrepreneurial Leadership, First Class, African Leadership University
