Think P2P.

We’re a global-thinking, ambitious generation trapped in centralized systems designed to profit a select few. Hard-earned money lies stagnant, steadily losing value as inflation rises. Loans are hard to access, and even more difficult to repay. It is easier to fly to some places than it is to send money there.
Today’s world is more connected than ever, but financial systems are still landlocked and insular, characterized by exclusivity, operating behind closed doors. The rapid growth of the P2P movement indicates a broken status quo, and reveals a world in common pursuit of financial autonomy. Everything we do at Constant is designed to make that goal more achievable.
It’s time to choose people, not institutions. This is a platform that connects all those in pursuit of a richer, more open world. Welcome to Constant.
