Why we exist

The payments industry has a transparency problem.

Every time you convert currency through your bank, a margin is embedded in the rate. It's not hidden in the small print, it's just never shown to you at all. Alt21 was built around one principle: you should see the full cost before you commit. Every time.

“I need to make regular payments in Euros and recently established my account with Alt 21. It was straight forward and Patricia and colleagues really attentive. Once the rate calculation was done I realised I had been leaving money on the table using my own bank previously!”

“The setup was painless and platform is simple to use. It is extremely competitive compared to the pillar banks and i'm fairly sure ALT21 will capture a large section of the FX market in time.”
