Trust is the only product that a challenger bank actually sells. The features — accounts, cards, transfers — are table stakes. What separates a fintech that grows from one that stalls is the speed at which new users answer one question: 'Is it safe to put my money here?' We designed for that question.
The Problem: Credibility Without History
Our client was a licensed challenger bank entering a market dominated by institutions with decades of brand equity. They had a strong product, regulatory approval, and a compelling fee structure. What they lacked was the visual and experiential signals that communicate safety to a first-time user who has never heard of them.
The original app and marketing site had been built quickly — focused on functionality over trust. The colour palette was aggressive (high-contrast neon on dark), the typography was display-heavy with no paragraph weight, and the onboarding flow asked for sensitive information — national ID, bank details — before it had established any reason for the user to comply.
Research Insight
In user interviews, 14 of 20 participants described the original app as feeling "like a startup, not a bank." Six of those 14 said they would not deposit more than £50 as a first transaction. Trust was the explicit objection — not features, not fees.
The Design Strategy: Trust as Architecture
We approached trust not as a feeling to be evoked but as a structure to be built. Trust in financial products is built from three components: competence signals (this organisation is capable), integrity signals (this organisation is honest), and benevolence signals (this organisation is working in my interest). Every design decision was mapped to one of these three.
Visual Identity: From Startup to Institution
We rebuilt the visual identity around two principles: permanence and precision. The colour palette moved from neon to a considered range of deep teal and warm neutrals — colours that read as stable, not exciting. The primary typeface was replaced with a variable font with strong serif characteristics in display sizes, communicating editorial seriousness. The logo was refined to remove the playful geometry of the original in favour of a mark that could comfortably appear next to a Visa logo.
Onboarding Sequence: Earn the Right to Ask
The original onboarding asked for national ID on screen three of a nine-screen flow. We restructured the sequence on a single principle: earn the right to ask for sensitive information before asking for it. The first four screens established who the bank was, showed the product in use, surfaced regulatory credentials and deposit protection details, and introduced a single low-commitment action — choosing an account type. Identity verification came only after the user had already made a product decision.
KYC Experience: Making Compliance Feel Safe
The KYC (Know Your Customer) step is where most challenger bank funnels lose users — it involves submitting a photo ID and, often, a selfie. We redesigned this step with three specific interventions: a clear explanation of why each piece of information was needed (regulatory requirement, not preference), a visible progress indicator showing exactly how many steps remained, and immediate inline confirmation at each step ('ID received — we'll verify in under 2 minutes'). The step went from feeling like a security wall to feeling like a checkout.

The Signal That Mattered Most
The first-deposit median value increase — from £43 to £210 — was the result we were least expecting and most revealing. Users weren't just completing onboarding at higher rates: they were starting with substantially more money. The design work had changed not just the completion rate but the depth of initial commitment.
This is the core insight from the project: trust design doesn't just reduce churn — it increases the initial stake that users are willing to place. When users feel safe, they don't just sign up. They commit.
- Visual identity was rebuilt around permanence and precision — signals that communicate institutional stability
- The onboarding sequence was restructured so every sensitive request was preceded by a reason to trust
- KYC was redesigned as a transparent, time-bounded step rather than an opaque security gate
- Regulatory credentials (FSCS protection, FCA authorisation) were surfaced at the moment of highest anxiety — not buried in the footer
- Inline confirmation at each step maintained momentum and reduced abandonment between screens
“The first deposit median going from £43 to £210 told us everything. Users didn't just trust us enough to sign up — they trusted us enough to actually bank with us.”
— CEO, Challenger Bank
Designing for Financial Trust
Trust in financial products cannot be faked with testimonials or security badges. It is built through the accumulated weight of every design decision — the colour that reads as stable, the typeface that reads as serious, the sequence that earns information rather than demanding it. Get these right and users will put their money where their trust is.
Takeaway
If your fintech onboarding is asking for sensitive information before it has given users a reason to trust you, you are losing the majority of your highest-intent applicants. Sequence matters as much as design.
