Driving growth in
a trust-first industry

Money is personal, so people are naturally careful about who they choose to manage it. Linxea knew that traditional ads weren't enough to build that kind of deep confidence.

Their goal was to move away from expensive marketing and let customers’ real-world trust drive growth. They wanted to prove that personal recommendations could attract more people than any other channel, all while keeping costs low.

The challenge

After struggling to acquire a high volume of customers with a previous referral provider,

Linxea faced several challenges:

Generating consistent customer acquisition through referral
Proving the effectiveness of advocacy as a scalable channel
Improving cost efficiency compared to other marketing channels

They needed a more effective approach to turn customer advocacy into a reliable, high-performing acquisition channel.

The solution:
thimproving performance through experimentation

Linxea partnered with Mention Me to build a more effective customer advocacy programme focused on performance and continuous optimisation.

The approach included:

Running regular experiments to improve campaign performance
Simplifying sharing options to increase customer participation
Using advocacy data to identify and activate high-value referrers
Creating targeted campaigns with higher incentives for top brand fans

Results: lower CPA and stronger acquisition performance

Linxea’s advocacy programme delivered strong, measurable results:

1

30% lower CPA than target

2

62% of customers shared the brand with friends

3

24% of referrals converted into new customers

4

40% referred customers came via Name Share®

Customer advocacy drove both higher engagement and more cost-effective acquisition.

Finding your most valuable fans through continuous testing

By continuously testing and analysing performance, Linxea was able to better understand what drives customers to share.

This enabled the team to:

Identify that fewer sharing options increased participation
Understand which customers were most likely to refer
Activate top referrers with higher-value incentives
Use advocacy data to improve campaign performance over time

This allowed Linxea to refine how it targeted, incentivised, and activated its most valuable customers.

What makes customer advocacy so effective?

Linxea’s results highlight the impact of customer advocacy:

It reduces customer acquisition costs
It drives higher conversion through trusted recommendations
It increases participation by optimising how customers share
It enables brands to identify and activate their most valuable customers

And because advocacy is built on trust, it provides a more efficient and reliable way to acquire new customers.

What Linxea says about customer advocacy

“We’ve always known that word-of-mouth is an extremely important marketing channel for us to build trust among our target consumers, but we needed to find the best possible solution to make it a success.

Mention Me was an easy choice. Our programme’s performance is constantly improving, and its CPA is consistently cheaper than our other channels. It’s been a game-changer for us.”
