Castle

The easiest way for businesses to buy Bitcoin. That is the short version of Castle. In practice that means accepting cards, bank transfers and wallets online or in person.

The natural audience is any business that takes money. They also list Bitcoin and FinTech, so expect those to show up in the feature set. As a very small product team themselves (1 to 10 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

Castle is based in Coral Gables, Florida and around since 2024. Their site is savewithcastle.com.

Before you commit, look at rates, payout timing, chargeback handling, and developer tools. Get the renewal terms in writing before the first invoice.
