Productized audits · in the field

Two ways a launch dies: a leaking funnel — or a regulator's no.

E-commerce bleeds revenue at the checkout. FinTech bleeds months in front of RBI, SEBI, SAMA and DFSA. Two productized audits, one senior team — pick your lane and watch it light up.

    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.

    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.
