The Opportunity

Problem

Students suffer high overdraft fees and poor customer service from banking apps marketed specifically for them.

Solution

Connects to your student bank app via Plaid to analyze spending patterns and send instant alerts to prevent overdrafts. Offers simple budgeting tools tailored for irregular student income like allowances and part-time gigs. Eliminates fees by automating transfers from a buffer savings account you set up.

Target Audience
