Custos is a concept project for a B2B AI treasury platform built for European CFOs and finance teams. The goal was to design a landing page that communicates institutional trust while making a complex financial product feel immediately understandable

The visual direction centers on a dark, premium palette with off-white typography and gold accents, referencing the language of private banking and asset management. Every section was designed with conversion in mind: a live treasury dashboard in the hero, a yield calculator that makes ROI tangible before any sales call, and a compliance trust bar that removes friction for enterprise buyers.

Full scope included brand identity, typography system, UI components, and a complete landing page from hero to footer

The design system was built to scale. Every component follows a strict grid, with typography and spacing decisions made to hold up across all screen sizes and future product pages. The goal was not just a landing page but a visual foundation that a real fintech team could hand off to developers and ship.

Typography and colour were treated as strategic decisions, not aesthetic ones. Biotif was chosen for its technical precision and neutral European character, trusted across leading fintech infrastructure products. The colour system pairs a near-black base with off-white text and a single gold accent reserved for high-value data points and CTAs, creating warm contrast without sacrificing the institutional weight the audience expects.

The logomark is built on a rotated square with a C letterform embedded in the negative space, referencing precision, structure, and containment. Clean enough to hold at any size, distinct enough to own in a crowded fintech landscape

Custos is a concept that proves fintech doesn't have to choose between trust and conversion. Every decision, from the typeface to the CTA copy, was made to move a CFO-level buyer one step closer to booking a demo.
