Why Castine

Independent

Castine is not broker owned. Client priorities set the roadmap. Your data and AI prompts are never shared. We never use your data to train our LLMs.

Modular

Every solution is built from proven building blocks. Start with the functionality you need most today, then add the rest as your needs change. Nothing forces you into a package.

Proven

Castine has never failed a client acceptance. Ever. The same systems scale from 5 users and 100,000 trades to 3,000 users and 3 billion trades. We've got you covered.
