Problem Statement

How might we optimise the user experience that is fun, friendly and social with a focus feedback loop while transacting money.


User Research

Demographic: The ages of 18 to 34. 

Friends and people who need to split, share payments.

User Personas

22, Female

Uses the app to send and request money from her roommates.

Often finds money in her account that she forgot about.

Paypal can be a competitor.

25, Male

Frequently uses it when going out with friends to split payments.

It's convenient and easy. Only hard when sending/ requesting money to a non friend.

Quickpay can be a competitor.

Key Insights

Users wanted their profile to be more  emphasize.

Users like the menu bar rather than a profile image.

Users were not using most of the existing touch points.

The speed of animation and feed back mattered a lot.

Style guide and colors need to cater Venmo.
