The Challenge

Prosper is a London based startup focused on helping high net worth customers maximise their potential wealth across their savings and investments. Naturally, the team applies the same philosophy to its own treasury. The goal was simple: ensure company cash works as hard as possible.

Prosper primarily banks with Revolut and HSBC, using Revolut’s interest-bearing accounts to generate yield on operational funds. However, the best rate available through Revolut was 3.25%, leaving a clear opportunity to earn more on excess cash.

The treasury problem:

• Revolut interest-bearing accounts limited to 3.25%
• Excess cash not earning optimal returns
• Limited access to higher-yield money market funds
• Traditional solutions required complex treasury structures

The quote:

“We’re an early-stage startup so every pound needs to work as hard as we do.”

• Brendan Murphy, CFO, Prosper

Alternatives Considered

Before choosing Round, Prosper evaluated several ways to deploy treasury funds.

For Treasury:

• Revolut savings - Easy to use but limited to 3.25% returns
• Treasury Spring - Structure and complexity unsuitable for Prosper’s needs
• Other platforms - Lacked maturity or the right balance of simplicity and yield

The core issue: Accessing higher-yield instruments typically required complexity that did not fit Prosper’s operating model.

The Solution

Prosper adopted Round to deploy excess treasury funds into money market funds while keeping access simple and flexible.
