heyData is a fast-growing Berlin-based data privacy platform with a high-performing internal marketing team
They were already running strong LinkedIn Ads campaigns in-house but wanted a partner who could help them push performance further
They partnered with Winbox through our In-House Accelerator package to get ongoing expert input, identify optimisation opportunities, and stay ahead of LinkedIn’s constant algorithm changes
Over 12 months, this hybrid model delivered a Return on Ad Spend (ROAS) of 4.39 while keeping campaign control firmly in-house

The support has been incredibly valuable. Having Marc on hand to sense-check ideas and provide strategic insight has made a massive difference.

heyData helps businesses simplify and strengthen their data privacy compliance. Their platform and expertise ensure clients can meet regulations confidently, without slowing growth.

Marco and his team already had:

A solid understanding of LinkedIn Ads
A proven track record running campaigns in-house
A desire to keep ownership of strategy and executio

But with LinkedIn being such a dynamic channel, they wanted an expert partner who could:

Pinpoint new opportunities for performance gains
Provide fast answers to technical questions
Share fresh ideas from working across dozens of other LinkedIn campaigns

The Approach

Through our In-House Accelerator package, Marco continued to lead heyData’s campaigns while we plugged in as specialist partners.

Every two weeks, we met to review performance, explore new targeting and creative ideas, and align on strategy. Between sessions, Marco had unlimited Slack access to our team for quick feedback – whether that was on ad formats, messaging ideas, or campaign setup questions.

We also gave heyData direct access to:

Insights from the 50+ LinkedIn Ads accounts we run
Creative input from our in-house design and copy teams
The latest platform updates from our LinkedIn agency partner status

This meant they could stay agile, avoid common pitfalls, and test new ideas with confidence — without the cost or overhead of a fully managed service.

The Results

With Winbox’s support, heyData achieved:

4.39 ROAS over a 12-month period
Faster testing and rollout of new ad formats and targeting strategies
A more agile and confident approach to campaign optimisation

The combination of in-house ownership and specialist input has kept heyData ahead of the curve — and ensured their LinkedIn Ads budget is working harder than ever.

It’s the perfect balance between internal control and external expertise.
