Shavekit drove 5x higher ROAS while cutting acquisition costs 76%

The challenge

Shavekit built its subscription business around a simple idea: make getting quality razors more convenient. Growing that business meant finding a reliable, repeatable source of new subscribers, but acquisition through mainstream social channels was getting more expensive, with limited transparency into what was actually driving results. Clicks and sign-ups were easy to report, but Shavekit couldn't easily tell which of them turned into paying, long-term customers.

The brand needed more than cheap sign-ups. It wanted a performance-based acquisition channel that could reach new audiences, deliver positive ROAS from day one, and bring in subscribers likely to stick around beyond their first order rather than cancelling after a single shipment.

The solution

We launched rewarded offer placements across Flash Rewards UK, connecting Shavekit with consumers who were already open to discovering and trying new products rather than just scrolling past another ad.

First-party insights, including postcode, device type, age, and gender, helped us identify and segment audiences closely aligned with Shavekit's actual customer base, instead of relying on broad social platform targeting. We then tailored offers and creative across those target demographics, focusing primarily on men ages 25–69 and women ages 25–59, with messaging built around what each segment was likely to respond to.

As performance data came in, we continuously adjusted the media mix and audience segmentation, pulling back on lower-converting traffic and pushing more investment toward the consumers who were producing stronger acquisition and retention results, so spend kept moving toward what was actually working rather than staying fixed in place.

Why it worked

Rewarded discovery gave Shavekit a way to introduce the brand to consumers who hadn't encountered it before, while audience segmentation made that discovery far more relevant to each one. Continuous optimization kept the campaign focused on the audiences converting most efficiently. And because we measured performance well beyond the initial acquisition, we could see whether new subscribers actually renewed, rather than treating every sign-up as equally valuable.

The result

We delivered a 110% ROAS, 5x higher than a leading social platform, while cutting cost per acquisition by 76%. Subscriber quality improved too. Shavekit's zero-renewal churn rate fell 60%, meaning fewer customers cancelled or landed in past-due status before their first renewal. The campaign gave Shavekit a more efficient acquisition channel, without trading lower costs for lower-quality subscribers.
