Diego Retamal
Product Designer focused on growth, systems, and real impact.
I design product experiences that move metrics — conversion, retention, activation. Not as a downstream executor, but as someone embedded in the problem from day one. I work at the intersection of product strategy, growth, and systems thinking, and I measure success in outcomes, not deliverables.
I treat design as a hypothesis. Before I open a design tool, I want to understand the funnel, the drop-off point, the user segment, and what the number looks like when we've won. UI is the last mile. The real leverage is upstream.
I have a strong experimentation bias. I've run A/B tests on critical acquisition and onboarding flows, instrumented designs to track post-launch behavior, and iterated based on data — not gut feel. Shipping is not the finish line.
I think in systems. Every one-off screen is a future liability. I default to reusable components, documented patterns, and composable logic — so the next feature is faster, cheaper, and more consistent than the last. Scale is a design problem.
I've spent years working directly with engineers, analysts, and growth marketers. I speak their language, challenge assumptions, and take accountability for what happens after the design ships.
CLARK's core promise is making insurance simple and transparent — but the offer view, the most critical moment in the acquisition funnel, was breaking that promise. Churn at that screen was at 60%. I led the end-to-end redesign: scoping the problem with data, running discovery, designing and testing multiple approaches, and running the A/B test that proved it.
- +28% contract conversion in the test group
- −35% drop-off at the offer screen
- −21% post-contract cancellations
- +10 NPS points on the internal satisfaction score
Beyond that project, I owned design across onboarding, switching, and cross-sell flows — building modular components reused across CRM, counter-offer, and in-app surfaces. Design as leverage, not output.
Brought in with a clear mandate: own e-commerce conversion and grow revenue. I ran CRO initiatives end-to-end — diagnosing funnel drop-off, designing and testing solutions, and staying in the loop until the numbers moved. No handoff culture, no "that's engineering's problem." Full ownership from discovery to post-launch impact.
- +23% checkout conversion rate
- −31% cart abandonment
- +17% average order value
Led the redesign of the cross-sell and checkout experience inside Mi Vodafone — 3M+ existing customers, multiple sales scenarios, one coherent product flow. I designed a modular purchase system covering discovery, plan configuration, and a unified checkout that could adapt to any in-app sales context. The checkout was adopted across the full app.
- 3M+ customers on redesigned flow
- +19% cross-sell conversion
- −44% steps to purchase
- Product strategy and problem framing
- CRO and funnel optimization
- A/B testing and experimentation design
- Data-informed decision making
- Design systems and component architecture
- Cross-functional ownership and alignment
- Mobile-first product thinking (iOS, Android, Web)
- I start from the problem, not the solution
- I validate with data, not opinions or seniority
- I ship fast, instrument properly, and iterate
- I build systems, not one-off screens
- I stay close to engineering — implementation details are design details
- I take accountability for outcomes, not just output
Product-led companies where design has a real seat at the table — not a service function. Teams working on genuine scale and growth problems where experimentation is a cultural default, not a quarterly initiative. I want ownership from problem definition to post-launch measurement. Not an executor role.
I spend time with Pepe — a long-legged dachshund with strong opinions and questionable decision-making.
He's not involved in product decisions (yet), but definitely keeps things grounded.
