I help e-commerce brands and funded startups turn traffic into revenue — through deep-dive CRO audits, funnel builds, and AI-powered optimization.
You're spending more than ever on ads. Meta CPMs keep rising. Google CPCs are at record highs. And now ChatGPT is launching ads at $60 CPM — 3× more expensive than Meta.
But here's what most agencies won't tell you: your ad spend isn't the problem. Your conversion rate is.
A 1% improvement in conversion rate can double your profit margin. I don't optimize your ads — I optimize what happens after the click.
My background is unusual for a CRO specialist — and that's the point. I studied aerospace engineering at TU Delft alongside legends like Wubbo Ockels and André Kuipers, and learned systems thinking from professors like Hans Wissema. I flew gliders. I understand aerodynamics. Which means I understand drag — and your checkout flow has a lot of it.
I've spent 17+ years at the intersection of engineering precision and growth marketing: optimizing funnels for e-commerce brands across Europe, building digital products, teaching mathematics and physics to hundreds of students, and staying ahead of every platform shift — from Facebook's algorithm to the rise of AI-powered search.
I don't run an agency with account managers. I work directly on your site, personally. You get engineering-grade analysis, not a PDF with generic recommendations.
"Juan delivered a thorough CRO audit that identified key improvements we had completely overlooked. His recommendations led to a measurable increase in our conversion rate within weeks of implementing."
"Exceptional attention to detail. Juan doesn't just point out problems — he provides a clear, prioritized roadmap with expected impact for each change. Unlike anything we'd seen from an agency."
"The funnel Juan built for us converted from day one. His engineering background shows — everything is systematic, measured, and optimized. No guesswork whatsoever."
"Based on the reviews I had high expectations and I still got surprised. He went far beyond the brief and delivered insights we hadn't even thought to ask for."
"Juan identified three checkout friction points that our agency had missed for months. We fixed them, and cart abandonment dropped 18% in the first week."
"I asked for a landing page review and got a complete reframe of our value proposition. The new page converted 2.4× better in the first A/B test. Absolutely worth it."
"He transformed our product page from a feature list into a story. Within two weeks of going live, our trial-to-paid conversion improved significantly. Juan thinks in terms of outcomes, not deliverables."
"The audit paid for itself within the first month. The copy rewrites alone were worth the price — specific, on-brand, and immediately deployable. Highest ROI vendor I've worked with."
