The bank with the 3rd highest ROE in Colombia.
This case study showcases the digital transformation driven by my area: Product.
As a leader, my main role was to define a clear roadmap and build effective methodologies to collaborate with the bank’s strategic teams.
As a specialist, I contributed to user research planning, UX/UI design, and the creation and management of the design system.
In doing so, we not only improved financial performance but also fostered creativity, innovation, agility, and a user-centered mindset across the entire organization.
Problem
In 2021, BMM needed to update its technological platforms (front and back office). This modernization was essential to stay competitive in the financial sector. One major challenge was the strong initial resistance — the bank had faced several failed transformation attempts, investing time, resources, and hope… yet seeing no results.
Strategic Challenges
Strategy: Immediate Value
The main challenge here wasn’t technical — it was cultural. We needed to shift mindsets to achieve true digital transformation, and with that in mind, I developed my work plan.
It was necessary to take a modular, area-by-area approach — prioritizing the creation of trust through quick, visible wins that demonstrated immediate value to both users and stakeholders.
Portal web & WhatsApp
BMM initially proposed implementing a WhatsApp Bot; however, I prioritized updating the website as a strategic starting point for several reasons:
And while monthly visits increased by 400%, reaching 3,500 leads per month, the most important outcome was that we validated our approach and built trust.
It turned out that customers preferred WhatsApp over traditional forms, so we took the bot to the next level — integrating it as an alternative within the website’s lead generation journey. The result: 95% of users chose to continue through WhatsApp, and the drop-off rate decreased from 40% to 30%.
From 20k →
100.000
Monthly visits — 68% organic, whereas most were previously paid
New Leads
3500+
Monthly — previously, we only reached 500 per month.
Drop-off
30%
A WhatsApp button helped us reduce the drop-off rate from 40% to 30%.
Banking App Optimization
With these early wins, we won the bank’s heart! We gained enough independence to decide which challenges to tackle next — focusing on the banking app and the commercial platform, the core of BMM’s operations.
The BMM User (User Persona)
With all the previous inputs, we developed a detailed BMM user profile that served as:
Design System y UX Library
Having led the creation of design systems in other companies, I knew that was the next step. We needed solid tools to build the foundation of our area. That’s why I proposed creating a base design system guided by the following principles:
This decision allowed the team to move faster in later projects, testing high-fidelity prototypes and validating ideas with agility.

Digital Onboarding:Credit, Savings Account, Investment
With validated tools and methodologies, we tackled one of the bank’s most critical processes: onboarding financial products through digital channels. This cross-functional effort involved:
The Result:
We radically transformed the customer experience by reducing credit disbursement time from 2 hours to just 5 minutes, enabling savings account openings in under 1 minute, and offering instant investments.
Modular Infrastructure:
We developed a modular architecture:
This modularity accelerated the creation of new features and optimized other processes in the branches, significantly improving the bank’s operational efficiency.
Consolidation:Product Management
The success of the previous stages allowed us to establish a formal Product Management area. With the trust we had gained, we were able to:
Thanks to the design system, thorough documentation, and user knowledge, we not only reduced risks but also cut product launch timelines from 1–2 years to just 4–8 months.
This strengthened position allowed us to participate in key innovations such as:
Selecting initiatives guided by data and user insights
No longer based on hierarchical decisions or what the tech team happened to suggest.

Key Takeaways
An effective digital transformation goes beyond technology — it integrates people, processes, and culture.
I witnessed an evolution that went beyond the digital. We restored something more valuable than code: trust. Not just in the technology, but in the bank’s ability to change without losing its essence.
We preserved the heart of the business: human relationships with independent workers and small business owners, often overlooked by traditional banking. Today, that transformation is felt in everyday experiences: in the client who understands how their credit works, the employee completing an operation in seconds, and the business owner receiving funding in minutes, all from home.
