Stephan Kulik
Stephan Kulik is the editor of Perpetuals Guide, an independent editorial site covering perpetual futures trading on centralized exchanges, and of its sibling site PerpDEX Guide, which covers decentralized perp venues. Every review, comparison, and guide on this site is published under his byline.
How the work gets done
The approach is the same on every page: fees, leverage caps, licence details, and program terms are taken from each venue's official documentation or the relevant regulator's own publications, and verified on the date shown on the page — never repeated from a third-party aggregator. Where a claim can't be verified, the page says so rather than guessing. Interface walkthroughs use screenshots from real, funded accounts, and the site only says it "traded" a venue when a live position or volume is actually visible in those screenshots. The full process is documented in the methodology.
Independence and funding
Perpetuals Guide is funded through affiliate programs of EU-regulated venues only, disclosed on every page that carries a referral link. Offshore venues are covered with no referral links at all. A referral relationship never changes a rating — see about for how that line is held.
