Turn your cash savers into investors.
Whistle helps your customers invest idle cash and unused ISA allowance through a guided, fully authorised experience embedded in your app.

01
£10,000 Sitting idle.
ProblemMillions of pounds sit idle in customer cash accounts every day, losing value to inflation. Unused ISA allowance and uninvested cash represent missed opportunities to improve customers' financial outcomes; yet most platforms have no way to act on them.
SolutionWhistle helps you identify these opportunities and enables customers to put their money to work through a guided, fully authorised investing experience, seamlessly embedded within your app.

02
Digital-first. Human-backed.
Whistle keeps customers in your app from first prompt to funded investment. Every recommendation is backed by a named, FCA-regulated adviser, with expert support available whenever it's needed.

03
One recommendation. Fully explained.
Whistle delivers a single, personalised recommendation with a clear explanation of why it's right for that customer. Every recommendation explains the chosen investment wrapper, risk profile, portfolio and projected outcomes clearly. A named, FCA-regulated adviser is always available whenever the customer wants expert guidance.
With a single approval, Whistle takes care of everything else. Investment accounts are opened, instructions are prepared and compliance checks run automatically in the background, allowing customers to move from advice to investment without ever leaving your app.
04
Same app. New investor.
One tap to authorise. From then on, investments sit alongside savings and everyday banking in the same trusted experience, with ongoing access to their adviser whenever they need support.
