Cuanto Case Study

I was challenged to create the ultimate shopping experience.

One of the first things I challenged early was the product positioning. Initially, Cuanto was being shaped as another cashback rewards app with an AI chat layer. But after deeper product conversations, I saw a much larger opportunity.

Rather than focusing only on cashback rewards, I pushed for the product to evolve into a complete AI-powered shopping experience — helping users discover the best matching products online before rewarding them for the purchase.

Working closely alongside the CEO and CTO, this direction reshaped both the product strategy and overall user experience, allowing us to position Cuanto as something far more valuable and differentiated within the market.

Design Thinking

Independent thinking, collaborative execution.
How we got results.

(01)

Product Positioning & Market Research.

Cuanto positioning research & competitive landscape

Market research helped uncover a stronger product opportunity that competitors were not yet combining. We would be unique.


After researching and benchmarking both cashback platforms and emerging AI shopping assistants, I realised there was a much larger product opportunity than simply building another rewards app in a saturated market.

Most competitors focused purely on cashback after the shopping experience, while newer AI commerce products focused on helping users discover products more intelligently. I saw an opportunity for Cuanto to combine both models into a single experience — helping users first discover the best matching products online, then rewarding them through cashback incentives.

(02)

Scalable, Dev-ready Figma System.

Cuanto Figma design system — tokens, components, patterns

By building a Figma system, we moved rapidly across 100+ screens / states without sacrificing usability or consistency.


Together with the CTO, I developed a scalable design system that allowed us to move quickly without building everything completely from scratch.

Rather than designing isolated screens, I focused on creating reusable foundations that could scale across devices, speed up implementation, and maintain consistency as the product evolved.

(03)

UX Strategy, Flows, Wireframes & Demos.

Cuanto UX flows, wireframes and onboarding explorations

Mapping flows, wireframes, and prototypes for this new product helped validate the direction and avoid complex iterations.


To speed up iteration, I started with wireframes and flows before high-fidelity UI. This helped us validate the AI shopping assistant model quickly, reduce unnecessary redesigns later, and confidently move into development and investor demos.

For example, since we were offering a new type of shopping experience, our onboarding strategy was critical to get right. I explored three approaches: 1. personalised onboarding, 2. AI-guided walkthrough, 3. interactive product simulation.

Between flow and conversion statistics, the interactive journey gave users the clearest understanding — so that's what we shipped.

(04)

Web & Conversion Strategy.

Cuanto web hero with in-line AI search

Everything users needed to make a decision was within the first glance of the site. The hero alone made users want, understand, trust, and start using the product immediately.


I identified early that users needed to experience the product value immediately — not just read about it. By placing the AI-powered shopping search directly in the hero section, users could instantly interact with the product before committing to sign up.

Since this was a new type of shopping experience, I focused heavily on making the product feel familiar from the beginning. Using recognisable UI patterns, trusted partner brands, and layered product information helped reduce friction, build trust quickly, and encourage stronger long-term engagement and retention.

(05)

Trust through Visual Brand Identity.

Cuanto brand guidelines — logo, typography, colour system

Simple design fixes improved recognition & searchability, while strong UI rules made us instantly more trustworthy as a new brand.


Cuanto already had its logo and primary colours established. I developed the wider brand foundations — typography, sizing systems, UI rules, iconography, and custom illustrations — to help the product feel more engaging, recognisable, and trustworthy for B2C users.

One major issue I identified was that the arrow within the type-logo caused the name to read as "Guanto" rather than "Cuanto". While subtle, this is the kind of flaw that can affect brand recognition and searchability online — so I adjusted the logo without needing a full redesign.

(06)

Responsive UI Product Designs.

Cuanto responsive UI

I delivered quality, strategically engineered screens using our new Figma system & components for seamless implementation.


Initially, the direction leaned heavily into a more technical AI aesthetic. Through iterations, I pushed the experience toward something cleaner and more approachable, as we were ultimately targeting everyday non-technical users.

I used familiar UI patterns, strong visual hierarchy, and reduced visual noise to make the experience feel intuitive immediately, while naturally guiding users toward product discovery and purchase actions.

(07)

Launch & Growth Marketing Assets.

Cuanto launch & growth marketing assets

The psychology behind making users stop, pay attention, and decide to download is often invisible within good design.


The product experience did not stop once the screens were finalised. A huge part of building a successful startup product is then getting those designs seen, understood, and trusted by users.

I designed the App Store visuals, social media content, and launch assets to communicate the product value within seconds. Strong branding, recognisable visuals, and custom illustrations helped the product stand out quickly, while also building trust and credibility with younger online shoppers.

(08)

Business Impact & User Results.

Cuanto growth snapshot — users, retention, GMV

20,000 installs · 10,000 active users · 40% retention · 21,000+ partner brands · $1M+ GMV processed monthly.


Following launch, within 6 months the platform reached 20,000 installs, 10,000 active users, 40% retention, over 21,000 partner brands including Nike, Walmart, Adidas, and SHEIN, and processed over $1M in GMV monthly.

I'm incredibly proud of how the product turned out, and grateful to have worked alongside such a strong team throughout the process. Together — myself, the CEO, and the CTO — were able to take the product from an idea to a product with real traction and measurable impact.

Next Steps

In true startup style, cuanto is still evolving.

Recently, the team identified an opportunity to pivot the product toward a new B2B market, partnering with other companies to give them access to the commerce infrastructure, chat experience, and partner network already built.

Since then, I have helped evolve the brand direction to feel more mature and aligned with the new B2B audience; shaping the dashboard platform UI direction, designing our pitch deck, marketing assets, and even the new team merchandise. Super excited for what's still being built here.
