About Us

Our clients tell us that amongst the reasons they work with us is that we provide sound and unbiased advice and that we ‘get it’. That means we never over-promise and under-deliver. Our management team first seeks to understand clients’ business and what they’re trying to achieve before suggesting whether we can help. The support we offer could be for a traditional marketing or telemarketing campaign, customer research or running a telemarketing training course. Our telemarketer team has also been described as offering an intelligent approach to cold calling. In addition to fantastic reporting and high levels of communication, this provides a recipe for success.

Our Telemarketing Team

We carefully select our telemarketers and reject more than we take on board. Our team is made up of high-quality individuals that we train for each campaign. No students or jobbing actors. Just mature, committed individuals that want to make a difference for our clients. They are therefore able to ‘engage’ and have peer to peer conversations with prospective clients to build rapport and identify their company problems (Pain) or opportunities (Gain) that our clients can resolve. That ensures that they deliver quality appointment setting for our clients.

Our clients have direct contact with their telemarketers and benefit from dedicated callers that operate seamlessly as part of their sales team. They also represent our clients’  business how they would like it presented.

  • I would happily recommend the team at GSA Business Development. We appointed GSA for telemarketing services to support our business development strategy. I was very impressed with the levels of focus and energy that the GSA team brought to the project - this helped to quickly identify new commercial opportunities. GSA had limited experience in our sector but they very quickly got up to speed and were able to provide us with a number of excellent opportunities that have subsequently been converted into new clients.
