A self-initiated website for Quilha, an invented fintech in São Paulo. Custom design and build: a single landing page, written in Portuguese.

Quilha is an invented business bank account for growing Brazilian companies, from sole traders to limited companies. The site is a single long landing page in Portuguese, because it was made for the Brazilian market.

The reader is a founder or a finance manager comparing business accounts. Before opening one, they want to see the fees, the features and how much idle cash earns.

Three account features (bulk payments through Pix, Brazil’s instant payment system, billing slips and ERP integration) in a sequence that holds the screen.

A hero with a 3D card that follows the page as you scroll, past a ticker tape of the account’s features.

A cards section with a team spending dashboard: one card per person, one limit per card.

A savings simulator that answers as you drag the balance and the period.

A pricing table and a final call to open an account.

The boldest of the five sites: violet, black and amber, a wide display typeface and very large type. The 3D card is drawn with WebGL, and a CSS card takes its place when WebGL or full motion is not available.

Every claim is specific to a business account and comes with concrete numbers on the page: fees, limits and the rate the simulator uses. No stock photos of handshakes or smiling teams.

Financial products are judged on trust and on numbers. A landing page has to show the fees, the limits and what the product does, and make signing up the obvious next step. I design and build product pages from scratch, with interactive pieces like this simulator when they help someone decide.
