Castle

Castle offers an automated Bitcoin treasury solution designed for small and medium-sized businesses. The platform enables companies to connect their payment processors and automatically convert a designated percentage of every transaction into Bitcoin, facilitating a strategy for long-term savings and wealth protection.

The service is built exclusively around Bitcoin, which the company favors for its fixed and unchangeable supply of 21 million, viewing it as a sound monetary asset for preserving business capital. The system includes features for streamlined bookkeeping to simplify financial management for its users.

Castle's business model is based on a transaction fee of approximately 1% on all Bitcoin purchases and sales conducted through the platform, with no additional spreads. The company offers a tiered subscription plan, including a free entry-level option and a 'Pro' plan with expanded features.
