About Us

Venmo was founded on the principles of breaking down the intimidating barriers around financial transactions to make them intuitive, friendly, and even fun. And it worked: people love sending money with Venmo, and we’re growing by leaps and bounds!

But we’re only just getting started. We want to take that magic of sending money with Venmo and cascade it into every place where people use money. That means connecting people to their money in the most intuitive and fun way possible, then connecting people with each other.
