Introducing · New Practice Area

High-Stakes UX. When small interface choices have life-changing consequences.

Most UX optimises for engagement, delight, and conversion. High-Stakes UX optimises for zero errors, decisions under pressure, and preventing catastrophic outcomes. A new Onyx practice for healthcare, defence, autonomous systems, FinTech KYC, AI co-pilots, and any product where a misclick is more than an inconvenience.

The Onyx framework

Four pillars for design under pressure.

Built on aviation human-factors, medical-device usability standards (IEC 62366), and Endsley’s situation-awareness model — layered on top of our TAPE framework. The same discipline that keeps cockpits safe, applied to the products founders are shipping today.

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 prevent them from becoming disasters.
C
Clarity under Chaos
Critical information communicated clearly when attention is limited and stakes are high.
S
Systems, not Screens
System thinking, safety logic, real-world impact — beyond surface UI polish.
Where it applies
  • Healthcare & medical devicesDosing, monitoring, surgery, emergency care.
  • FinTech KYC & transaction flowsOne wrong field locks a user out for two weeks.
  • AI co-pilots & agentsWhen the AI decides, the human needs to understand why.
  • Autonomous systems & defenceHandover alerts and perception displays.
  • Industrial & aviationControl panels, alarm hierarchy, mode awareness.

Anyone can design with AI in 2026. Almost no one can design for the moment when the AI is wrong — and a human has 90 seconds to catch it.

— Amolendu Hajraa, Founder

23 years of judgement. AI speed. The killer combination.

Pillar 01

23 years of shipping what works.

  • 23 years of UX across FinTech, e-commerce, B2B SaaS, EdTech, 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 know the answer.
Pillar 02 · Our Moat

A founder’s brain, inside the LLM.

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

When we use Claude Opus 4.7 or GPT-5, the model reasons with our founder’s actual playbook, not generic internet training data. AI-fast, plus a senior product mind that has seen this problem before.

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