Envelope was founded by Katelyn and Josh Strobel, a husband-and-wife team who built Envelope from their own experience using envelope-style budgeting to manage family finances.

Katelyn is the CEO and cofounder of Envelope. Before starting Envelope, she managed millions of dollars in advertising spend for fintech companies and products, including Apple Card, Acorns, Credit Karma, MoneyLion, Robinhood, and Digit.

Josh is the CTO and cofounder of Envelope. He previously worked as an iOS engineer at Robinhood, Twitter, and Tesla.

Together, Katelyn and Josh have used envelope-style budgeting for more than six years. They believe strongly in financial minimalism, the one-card method, and simple tools that help families organize spending, plan ahead, and stay focused on their financial goals.
