Why we built these
Demivolt builds calm, modern money infrastructure for European businesses. The tools on this page exist to make the day-to-day finance work around SEPA payments a little less painful — checking that a counterparty IBAN is well-formed before sending a payment, or estimating what your monthly transfer costs will look like under different providers. They are deliberately simple, free, and run entirely on your device. If you find them useful and want to see what we offer beyond the tools, take a look at our product.
