Sascha Martins
Founder of Promo Code Network, based in Altendorf, Switzerland. Sascha runs the site alone: he holds the exchange, VPN, hosting and charting accounts the site is built on, tests every code on the operators’ live pages, writes every page, and records the walkthrough videos on the CapitalCommander YouTube channel.

Background
Sascha started Promo Code Network in 2026 after years of using referral codes from coupon sites and finding that most were expired, mislabelled or set to pay the referrer more than the user. The site’s rule follows from that experience: a code is listed only after it has been entered on the operator’s live signup page and the page has shown what it pays.
What he can speak to from his own accounts: how the Binance and Bybit referral programmes attach codes and pay rebates, what the exchanges charge at the base fee tier, how NordVPN prices its campaigns per country, how Kinsta’s annual billing and first free month work, and what TradingView’s plans and trials include. Claims outside that are sourced to the operators’ published pages and marked as such.
What he is not: a licensed financial adviser. Nothing on this site is investment advice.
