Client stories
Loved by teams in every market.
4.9/5 average client rating
“The list quality was the first thing we noticed — bounce rates dropped sharply and our reps stopped wasting mornings on dead numbers. It simply works.”
“They rebuilt our target-account list around a tight ICP, then verified every contact. Our outreach finally reached decision-makers instead of generic inboxes.”
“Réactifs, clairs et sérieux. The data was accurate, the reporting was honest, and our pipeline for the DACH and French markets finally started to fill.”
How accurate is your data?
Our data averages 95% accuracy or higher at the point of delivery, measured on email deliverability and contact validity. Every record passes multi-step verification, and if records bounce or turn out to be wrong within the agreed window, we replace them at no extra cost.
Where does your data come from?
We combine publicly available business sources, licensed data partners and our own research team. Every record is verified before delivery, and we can document the source of any contact on request.
Which countries and industries do you cover?
We cover 30+ countries, with the deepest coverage in the USA, the UK, France, Germany and the wider EU, plus Canada, the Middle East and Asia-Pacific. Our contacts span technology, healthcare and life sciences, financial services, manufacturing, education, retail and more.
Is your data GDPR and CCPA compliant?
Our data practices are designed to align with GDPR, the California Consumer Privacy Act (CCPA/CPRA), CAN-SPAM and other applicable regulations. We work with business contact data, honor opt-outs and suppression lists, and help you set up compliant outreach. We recommend you also review your own obligations with legal counsel.
How quickly can you deliver?
Most data appending and list-building projects are delivered within a few business days, depending on volume and how specific your targeting is. Outreach and appointment-setting programs typically launch within two weeks of kick-off. We confirm timelines before we start.
How is your pricing structured?
Pricing depends on the service, volume and targeting depth. Data work is usually priced per verified record; campaigns and appointment setting are priced as monthly programs or per qualified meeting. Tell us your goals and we will send a clear, fixed quote — no hidden fees.
Is there a minimum order?
We keep minimums low so you can test us properly. Many clients start with a small pilot list or a short campaign, review the results, and then scale up.
Can I get a sample before I commit?
Yes. Share your ideal customer profile and we can prepare a small sample so you can check the fit and quality yourself before placing a full order.
