BuildingFintechFromZero

DINN 1.0 was functional and almost a year live, with near-zero users. No one had asked young Mexicans why they weren't investing — or how they wanted to.

Every competitor in Mexico was communicating in functional territory — rates, features, security badges. Nobody had claimed the emotional and educational space. Nobody was talking to young people about their relationship with money.

What the research told us about the target:

1. Don't build for investors. Build for savers who don't know they can invest. The target already had the behavior (saving) but not the mental model (investing). Product thesis: simple savings account + you earn returns. One step, no minimum.

2. Own the emotional territory. Every competitor talked rates and features. We positioned at the intersection of simple and earning: "DINN: Simple + Your money earns."

3. Design the behavioral change, not just the product. We used BJ Fogg's Behavior Model — Motivation, Ability, Trigger — as the launch framework, and mapped all three.

DINN 2.0 — Wireframes

Brand and product were designed in parallel — the identity had to read simple and credible at once, a hard balance in fintech. Every element went through user testing before development.

The product became the simplest in the market: sign up, deposit, and your money is automatically invested.

In early 2020 we launched the DINN debit card, so users could spend their money day to day.

From a near-zero v1 to 500K+ users. The same insight drove all of it: meet people where their behavior already is, and remove the barrier — not the product — that stops the next step.
