Plat2 is the internal name for iugu’s new platform, focused on making all products fully modular. Inspired by the App Store and the AWS model, the system allows users to add and contract modules to build the product according to their needs, with complete autonomy. Additionally, the platform provides infrastructure for partners to offer their own applications, which can be contracted together with the iugu structure.
Abstract
The financial services market has been evolving toward more flexible and customizable models. However, many platforms still deliver rigid products with little freedom of choice for customers. This represents a clear opportunity: offering a solution where users build exactly what they need, without paying for features they don’t use.
Modularity was the key point of this project. We needed to transform an already established product — such as iugu Cobrança, which is already composed of a large group of applications — into something modular from its core, without losing the ease of use that customers already know. Additionally, the platform needed to support an app store, a central workspace, and customizable profiles.
With this scenario in mind, I structured the design process prioritizing modular consistency, clarity in module contracting, and a technical foundation that would allow scale and continuous evolution.
Process
Research and understanding
The first step was dedicated to research, including interviews and data gathering. We sought to understand real user needs, current usage patterns, and pain points related to the lack of modularity. This information guided the entire design strategy.
Creating the style library
With the data in hand, we created a style library to validate with the development team and the product owner. This step ensured that the visual language was consistent, scalable, and technically feasible before moving on to the screens.
Development and validation of basic screens
The essential screens of the product were developed and validated with the product and development teams. We adjusted flows, fixed friction points, and ensured the basic navigation made sense.
Creating new pages
Next, we developed the store pages (for contracting modules and partner apps), the central workspace, and the user profile. These screens form the core of the modular experience.
Global validation and execution follow-up
We conducted a global validation of the product with key stakeholders and teams. After approval, we closely followed the development execution, reviewing implementations and clarifying questions.
Continuous improvement and using AI to manage the Design System
The project includes a continuous improvement process. We use AI to help manage the Design System, ensuring consistency and agility in updates.
Solution
The project is in progress, with important steps being applied each month. Because this is an innovation in the business model, we are validating the new product alongside the current product, ensuring proper functionality so that a future transition occurs smoothly and without disruption for existing customers.
