GroeiLeaders

Client Background

We’ve been working with GroeiLeaders in a white-label partnership for close to a year. In this setup, we operate behind the scenes as their outbound automation engine, building and running sales systems on behalf of their clients. 

GroeiLeaders brings the client relationships and commercial strategy. We bring the technical infrastructure, the Clay workflows, the data enrichment, and the campaign execution. 

Together, we’ve served five distinct B2B companies from their portfolio, each with different industries, audiences, and sales challenges, but all stuck in the same trap: manual prospecting that couldn’t scale.

The Challenge

The businesses in GroeiLeaders’ portfolio shared a common set of problems. 

• None of them could afford a full marketing and sales team, so the founders were doing everything themselves. 

• Most had tried some form of cold outreach on their own, usually buying a list and sending emails, and concluded that outbound didn’t work. 

• Others were entirely dependent on referrals, which felt comfortable until the pipeline dried up with no backup plan.

One client, a publishing company called Uitgeverij Gorcum, had its founder sitting at his desk until 9pm every night researching prospects manually and finding maybe 15 contacts a day. 

Another, IBD Trade, was trying to sell sustainable products to daycare centers but couldn’t crack a market where decision-makers aren't on LinkedIn and don't appreciate cold calls. 

A third, AirSave, was reaching out to industrial facility managers who barely check email during their shifts. 

In every case, the approach was wrong, the tools were missing, and the process couldn’t keep up with the opportunity.

Our Solution

For each client, we started with proper discovery work to understand their ideal customer, then built custom workflows that automated their entire prospecting and outreach process. 

For Uitgeverij Gorcum, we expanded their target market beyond the obvious (educational companies) to include leisure and lifestyle brands that wanted to reach teachers, then automated the full pipeline from list building to personalized email campaigns. They had confirmed advertising deals within the first week.

For AirSave, we learned that email wasn’t the right primary channel for industrial facility managers. We used email engagement data to build warm call lists with conversation starters and timing recommendations, which pushed phone connection rates above 50%.

For IBD Trade, we identified daycare centers as an “untouched market” that rarely gets professional sales outreach and ran campaigns to general inquiry emails. The response was massive: 82 out of 194 prospects signed up for free samples, a 30 to 40 percent response rate that outperformed two years of previous marketing in four months.

For Helixis IT and Datatako, we layered intent signals and use-case-specific messaging on top of automated outreach to make every touchpoint feel timely and relevant rather than generic.

And there’s more.

Results

• 20+ hours saved per week per client on manual sales activities, freeing founders to focus on product and delivery.

• Response rates of 2.5% to 30% across campaigns, compared to the 1% or less their previous efforts were producing.

• Confirmed deals within the first week for Uitgeverij Gorcum after launching automated campaigns.

• 82 sample requests from 194 prospects for IBD Trade, generating more qualified leads in four months than their previous two years of marketing combined.
