Job Description
About Us
Trustyfy is a global tech company building the first DeFi bank for companies and individuals.
For the first time in history since the invention of banking, customers – not banks – can have full ownership of their money.
- Thanks to our proprietary multi-signature and decentralized technology, companies can work internationally with no risk of payment delays, and at a fraction of the cost of legacy banks.
- Workers can remit funds to their loved ones at almost no cost.
- And two billion unbanked can become financially independent.
We have validated the vision and secured the capital from both recurring revenues and a seed round. Now, we are leveling up our leadership.
