Longevityplus.pl: from a blank page to Poland’s largest test marketplace, with 1,622% growth
Longevityplus.pl sells diagnostic tests and health check-ups online. It started in 2015 as Zdrowegeny.pl, when the Internet Ventures Fund from the MCI Capital group saw a gap in Polish medical diagnostics: tests people could order without visiting a clinic. Together with MCI we designed and built it from scratch, and Greenlogic, the team that builds Firecrux, was responsible for the brand, the system and online marketing.

The challenge
When the fund set up the company, ordering medical tests remotely was practically unknown in Poland. The new company needed a brand, an online marketplace and the system behind it, all built from scratch.
What we built
- The brand and the online marketplace for genetic tests, including prenatal tests, cancer screening, dietary, blood and intimate tests, performed by many medical labs.
- The system behind it, from ordering to results.
- Online marketing, a new design in 2020 and a new backend in 2021.
Results
- The marketplace, then Zdrowegeny.pl, became the largest in Poland for diagnostic tests for individual customers.
- In March 2018 MCI sold the company to Diagnostyka, an industry investor, which kept the marketplace running with tests from many labs.
- In 2021 it took 11th place in Deloitte Technology Fast 50 Central Europe, with 1,622% revenue growth.

Its content today
A health brand needs a lot of content, and every sentence has to be right. Instead of a newsroom of medical writers, the Longevityplus.pl guide is written this way:
- Topics come from the client’s search data: questions the site does not answer yet, and pages that are losing traffic.
- Our AI engine studies Google’s top results for each topic, drafts the article and checks its claims against sources, and our editors edit every text.
- Nothing goes live without the client: their team approves each finished text in the Client Portal.
- Firecrux tracks every page after publication, suggests a refresh when it starts to slip, and measures each change in Search Console for 28 days before and after.
Timeline
- 2015: the company is founded as Zdrowegeny.pl on MCI’s initiative, and we build the brand, the marketplace and the system.
- 2018: MCI sells all its shares to Diagnostyka.
- 2020: a new design.
- 2021: a new backend.
- Today: the business operates as Longevityplus.pl, and we run its SEO and content in Firecrux Digital Intelligence.
