Helping Exponent Launch a Tailored Spend App for Restaurant Owners—Through Design

Exponent Fi - Smarter Spending for Modern Teams

Exponent is a B2B fintech company that provides company credit cards that generate cash back to employees of other businesses. These are not personal cards — they're built specifically for business purchases such as dining, supplies, inspections, cleaning, and equipment.

The app is effective in tracking spends, and has a QuickBook integration that helps to keep track of tickets and transactions. The company's mission is to simplify how businesses manage operational expenses through smart, easy-to-use financial tools, with a fully mobile-first experience.

The Impact

Our collaboration with Exponent Fi resulted in a sleek, intuitive mobile experience that empowered restaurant owners and operators to take control of their spending, without friction or confusion. The redesigned app helped Exponent:

Launch a fully functional product on time, ready for pilot testing with early customers.
Streamline expense tracking and reconciliation, reducing time spent on manual data entry and approvals.
Increase user adoption by delivering a familiar yet refined UX aligned with industry standards.
Strengthen their product positioning as a modern, mobile-first financial tool built for small business agility.

The outcome: a product that feels effortless to use, yet powerful in function, turning complex spend management into a simple, daily habit for business owners.

How We Got There

We kicked off with a Design Sprint to align around the core user needs of restaurant owners and identify the most valuable use cases for a mobile-first spend app. From there, we built an MVP/Proof of Concept that validated key flows, such as spend tracking, receipt matching, and analytics, through rapid prototyping and real user feedback.

To ensure accessibility and scalability, we adopted a Web-Enabled Mobile approach, allowing Exponent Fi to deliver a responsive, app-like experience without sacrificing speed or usability.

Finally, we introduced AI enablement as a foundation for future features like automatic categorization and spend insights, helping Exponent evolve toward smarter, more proactive financial management.
