From Launch to Top 50: How PocDoc Climbed Amazon UK’s Health Rankings in 2026

Four months ago, PocDoc had zero Amazon sales.

Last week, our Cholesterol Home Test Kit is in the Amazon UK Top 50 Best Sellers - across all test categories. That includes COVID, pregnancy tests, glucose monitors and household names that have dominated for years.

Even more importantly: it's already profitable.

Here's what we learned - and secrets CEOs have revealed in winning Amazon over:

1) Identifying Limiting Factors - Fast

Amazon isn't primarily a marketing challenge. It's an operations and logistics challenge.

Stock availability. Lead times. Cash flow. Review velocity. Rank momentum.

If you don't identify your bottleneck early, Amazon will find it for you.

For us, speed of iteration and operational readiness were critical. Once demand started compounding, the constraint wasn't "can we sell this" - it was "can we fulfil at scale without breaking unit economics?"

Winning on Amazon means treating it like a high-performance supply chain machine, not just a storefront.

2) Dedicate Real Cross-Functional Time

Amazon cannot be a side project. 

The companies that scale on Amazon dedicate focused time from: 

• Finance - margin modelling, cash cycle, ad efficiency
• Operations & Manufacturing - inventory forecasting, packaging optimisation
• Marketing - content, coversion, PPC, ranking strategy

3) Set Aside Budget to Build, Launch & Grow

Amazon requires investment - but not reckless spend.

You need budget for:

• Launch velocity
• Reviews and ranking strategy
• Paid search
• Creative optimisation
• Inventory buffers

The good news?

It doesn't require Super Bowl-level budgets. Because with the right product-market fit and strong unit economics, Amazon becomes self-funding.

Steve Roest, CEO and Co-Founder at PocDoc said: 

"If you re-ranked the Top 50 based on UK-manufactured tests.

We'd be number 1.

Because we're the only one manufacturing in the UK."

Breaking into the Top 50 Best Sellers across all test kits in the UK - from zero sales four months ago - proves something important:

Healthcare consumers are ready for trusted, accessible home diagnostics. But distribution alone, doesn't create success. Execution does.
