Marko P.

I increase the number of paid users by 30%+ for fintech apps and products in 3-6 month PLG design experiment sprints. Growth breaks in predictable places: activation is weak, users don't reach value fast enough, retention leaks, and revenue stops scaling with traffic. I fix that at the product layer by restructuring how the product drives activation, habit, and trust. Recent results: +230% paid customers lift (TradeVision, 2026) +30% paywall conversion lift, in a 6-week sprint (fintech client, 2026) +140% day 30 retention in a 1-month sprint (fintech client, 2026) Top 1% on Upwork. Expert-Vetted. What I do I define the problem thesis, the target user and job-to-be-done, and the metrics that actually matter. Then run an experiment roadmap against them. Core focus areas: - Activation baselines - LTV expansion - Onboarding drop-off - Time-to-value - Retention loops - Monetization logic & paywall design - Instrumentation clarity (Mixpanel, PostHog) - Experiment frameworks The shift I drive: from "users signed up" to "users reached value and stayed." I'm a strong fit if: - You're building in fintech, embedded finance, or AI SaaS - Growth is inconsistent or plateauing - Activation is weak or retention feels fragile - Your product is powerful but misunderstood - You want product strategy, not just UI execution Not a fit if: - You want a cosmetic redesign only - You don't measure activation or retention - You're optimizing for the cheapest hourly rate - There's no decision authority on your side I'm a 2x startup founder I've been on the other side of this. I built and scaled a contactless payments product from zero: a QR-code checkout via Apple Pay or bank card, adopted by cafes and restaurants across Serbia, with early VC interest Then hit the same wall I now help founders avoid: strong design and UX, but no PLG structure behind it. Growth stalled and the company didn't make it past that stage. If your product needs sharper activation, stronger retention, and clearer monetization logic, let's talk. --- "Marko is the best, most professional and dedicated designer I've worked with." — Adam, Co-Founder, MindsDB "Marko quickly understood the complexity of our product and turned it into intuitive, user-friendly flows." — Tim, Founder & Managing Director, Archlet "Marko was great to work with.
