The Customer: ScaleFlow — B2B Project Management Software
ScaleFlow's sales team was spending up to 15 hours a week manually searching for contact information for IT decision-makers. Bulk lists from legacy data vendors produced email bounce rates above 22% and inaccurate phone numbers.
ScaleFlow switched to LastDatabase for verified, job-title-specific lead lists. Precision filtering by technology stack and country helped the team build targeted direct-dial lists for C-level technology executives across Europe and North America.
“LastDatabase completely changed our outbound strategy. We stopped wasting money on stale data and finally got direct access to decision-makers who actually respond.”
The Customer: Aura Direct — Regional E-Commerce & Retail Brand
Aura Direct needed clean, active mobile contacts for a major flash sale across Southeast Asia and the UK. The team wanted high-intent consumer segments for SMS and WhatsApp without overspending on unverified leads.
Aura Direct used LastDatabase country-specific B2C consumer lists with pay-per-lead filtering. The team selected cell phone contacts by city and demographic criteria and evaluated 50 free sample records before purchasing.
“When running high-volume SMS campaigns, bad data costs money twice—once for the list and once for the carrier send fee. LastDatabase's list quality gave us our highest-converting SMS campaign to date.”
The Customer: LeadVanguard — Full-Service Performance Marketing Agency
Managing outbound campaigns for more than 20 B2B clients required constant data sourcing. Slow delivery from custom lead brokers created frequent onboarding delays for new clients.
LeadVanguard adopted LastDatabase as its primary data enrichment and lead provider. The agency used monthly access to source tailored email, phone, and social-profile lists across industries including logistics and fintech.
“On-demand access to targeted data removed a major bottleneck from our client onboarding process. Our teams can build the audience they need without waiting weeks for custom list delivery.”
