The Client

Saving money, made gratifying.

Grand is one of the pioneering mobile apps in America that makes saving money more gratifying. Built on the Prize-Linked Savings concept, it gives users a lottery-like experience — incentivizing them for every dollar they save.

Amid today's lackluster bank interest rates, Grand's platform is an innovative way to encourage Americans — especially millennials — to save more while having fun with cash prizes.

The Challenge

Every login is tied to a real bank account.

In the early days, Grand relied on its in-house dev team. As the product matured, demand for new features, updates, and bug fixes kept growing faster than the team could ship.

And security is paramount: every user's login is linked to their bank account, so extra steps have to protect their data at every point in the experience.

The Process

We rebuilt the back-end and remodeled the features that matter.

Grand came to Silicon Prime to overhaul its existing apps and sharpen the UX for clean functionality. We restructured the back-end to rebuild the four features users touch most.

Dashboard display

A cleaner home screen that puts savings, entries, and the next draw front and center.

Recurring savings

Set-and-forget auto-save so every contribution earns more chances to win, hands-free.

Prize drawings

A reliable, transparent draw engine — the lottery-like thrill that makes saving fun.

In-app referrals

A built-in referral program that rewards members for bringing friends along to save.

Less is more — so we simplified until saving felt effortless.

In their words

We have worked with Silicon Prime since January of 2019 and have found them to be wonderful partners. We are constantly amazed at their professionalism and attention to detail, and how they consistently show the same amount of pride for the product as we do. This work ethic also applies to code reviews, security and general testing. We know that if they are working on it, it will be thought through, and built with intention. They also communicate very well, and manage to work effectively across time zones. We look forward to working with them for a long time to come.
