We designed and built the platform and still develop it.

How we start

No technical spec? That's where we start.

Bring the business plan, your partners and a deadline. In a few weeks we turn them into a product definition and an architecture you can build on.

The questions we settle with you
Roles and permissions
Who can do what: customers, operators, partners?
Compliance checks
Where do KYC/KYB, sanctions screening and transaction monitoring sit in the flow?
Flow of funds
Where does money come in, where is it held, and how does it settle?
Providers and rails
Which provider handles each step, and over which rail?
Exceptions
What happens when a provider fails, a payment is returned, or the balances don't match?
Fees and pricing
Who pays which fee, when is it charged, and how does it show on the statement?
