Telemarketing, Data Building & Lead Generation Specialists

Database Building & Validation for Marketing & Lead Generation

Poor quality or ‘dirty’ data means wasted time and money, inefficiency and slower results. Managing and updating your data accurately, regularly and legally enhances the possibility of generating profitable new business.

Regular database cleaning & validation are critical for effective lead generation. Accurate list gathering and data building are essential to any outbound direct marketing or telemarketing campaign. Whether you use LinkedIn for lead generation and data gathering or Google to research names and companies, good, reliable data is the platform for a successful telemarketing campaign.

We our customers

Here's what they say about us:

"We approached Jonathan Silverman to act as a facilitator and to provide strategic input to an Intranet development meeting held in the UK. I have worked with Jonathan previously on a number of marketing forums that required input in planning, facilitation, review of outcomes and strategic recommendations. Jonathan has an extremely broad knowledge of the world of marketing communications and it is this experience that enables him to lead discussion in such an authorative way. Jonathan also has an excellent understanding of global cultural sensitivities which was essential in planning our future global marketing strategies." Director G4S plc
"3 days of telemarketing to approx 50 publishers. I felt both Viv and Emmy provided an excellent service, were approachable, clear in their intentions and delivered an excellent service. The results of which were better than anticipated and I would not hesitate to use or recommend their services" Director Fran Ryba Consultancy
"Jonathan had been recommended to us, which is always a good indication, although not of course a guarantee that he could meet our requirements. Upon meeting us for an initial consultation, however, it became very clear, very soon, that he understood our business, our needs and how we could best address them. The result was a training package that incorporated all of our development requirements, delivered in an enthusing manner which spread to all of the delegates — including the more sceptical one’s! With a strong emphasis on follow-up and continual development, our Sales Team are benefiting greatly from Jonathan’s guidance — long after he has visited. " Managing Director Office Furniture Company
