How Flagstone
makes money

For each account you open with our bank partners through Flagstone, we receive a small share of the interest. We deduct that share before we feature any account in our platform – so the rate you see will always be the rate you receive.

We don’t charge admin, management, or platform fees.

This is how our share of the interest works →

We’re at your service.
