The guarantee

Conversion lift in 90 days — or we keep working free.

You're already paying for the traffic. We rebuild the funnel around how people actually decide — trust, friction, proof — and ship A/B tests at AI speed instead of agency speed.

The numbers on the right aren't projections. They shipped, in production, for real founders.

Why Onyx · 2026

23 years of judgement at AI speed.

We ship in days, not months — without trading away the senior thinking that makes the difference between a redesign and a result.

Pillar 01

23 years of shipping what works.

  • 23 years of UX across FinTech, e-commerce, B2B SaaS, EdTech and InsurTech.
  • Worked with Walmart, Porsche, S&P Global, Pepperfry, TerraPay, Briq.
  • 15+ FinTech apps, 20+ B2B SaaS products, $600M+ raised by clients.
  • Not a CV — pattern recognition. We look at your problem and probably already know the answer.
Pillar 02 · Our moat

A founder's brain, inside the LLM.

Over two years our founder encoded 23 years of product decisions, conversion patterns and case outcomes into a private knowledge base that powers our AI workflow.

So when we use Claude or GPT-5, the model reasons with our founder's actual playbook — not generic internet training data. AI-fast, plus a senior mind that has seen this problem before.

Result — 87% time saved on research, wireframes and MVP design, at the same quality bar.

New practice area

High-Stakes UX — when a misclick is more than an inconvenience.

Most UX optimises for engagement and conversion. High-Stakes UX optimises for zero errors, decisions under pressure, and preventing catastrophic outcomes — for healthcare, defence, autonomous systems, FinTech KYC and AI co-pilots.

P

Design for pressure

Interfaces that stay usable when users are stressed, rushed or cognitively overloaded.

E

Design for human error

Systems that expect mistakes and stop them becoming disasters.

C

Clarity under chaos

Critical information made clear when attention is limited and stakes are high.

S

Systems, not screens

Safety logic and real-world impact, beyond surface UI polish.

  • Healthcare & medical devicesDosing, monitoring, surgery, emergency care.
  • FinTech KYC & transactionsOne wrong field locks a user out for two weeks.
  • AI co-pilots & agentsWhen the AI decides, the human needs to know why.
  • Autonomous systems & defenceHandover alerts and perception displays.
  • Industrial & aviationControl panels, alarm hierarchy, mode awareness.
Sector expertise

Specialists across sectors.

From e-commerce to experience centres, we've shipped products inside the regulatory rails and conversion patterns of each.
