Challenge

The agency faced three critical obstacles:

Outdated and incomplete data: Many contacts were inactive, companies dissolved or merged, making outreach inefficient.
Wasted effort on irrelevant prospects: Time and resources were spent on companies that didn’t match the service profile or were unqualified.
Lack of insight into company-change signals: The team lacked visibility into key events (e.g., funding, leadership changes, growth) that might signal a business is seeking their services.

As a result, the agency’s prospecting efforts were slow and inconsistent, preventing predictable growth.

Solution

By partnering with DataGardener, the agency gained access to a modern business-intelligence platform that delivered:

Automatic cleansing and refreshing of contact and company data — eliminating obsolete records.
Alerts on significant company events (growth, new directors, funding) to help the team engage at the right moment.
Improved targeting through accurate, timely data so that the team could focus only on high-likelihood prospects.

These capabilities allowed the agency to move from reactive outreach to proactive, insight-driven prospecting.

Results

Within the first year of implementing DataGardener:

+45% increase in new client acquisition.
Prospecting time was reduced by approximately 50% (the team spent half as much time on zero-hit leads).
Targeting became significantly more precise, leading to higher conversion rates from prospecting.
A steady pipeline of high-quality opportunities was established, making growth more predictable.

“In short: the agency moved from stalled, manual efforts to a structured, data-intelligent growth engine.”

Client Feedback

“Integrating DataGardener has completely transformed the way we manage data. Our CRM is now accurate, dynamic and aligned with our go-to-market strategy. The team no longer wastes time chasing outdated leads — they focus on high-quality, relevant opportunities. It’s significantly improved both our efficiency and confidence in outbound campaigns.”
