About Lead Generation.

Sales Lead Generation is a must-have for nearly all businesses, whether you are a small business or a Fortune 500 company. The purpose is simple; find prospective businesses with the appropriate pain points that your products and services eliminate. We want your prospects to see your products and services as viable solutions to their existing problems. Most often, this is done through cold calling efforts to a defined target audience. However, sales lead generation can also be used to follow up on trade show contacts, webinar attendees, website inquiries, or even older prospects that you have not reached out to for several months or years. Outsourcing is a great way to cut your work and effort in half while improving your business. By outsourcing, you leave enough time for your company and its many sales teams to work on the product or to better provide a service from the many clients that outsourcing will bring in.

Our Approach.

Grindstone does not simply call your prospects using a canned script. Our highly experienced team learns the ins and outs of your products and services, value proposition, and key differentiators to tailor a customized calling program. We take the time to get to know your company and after extensive in-depth research, we customize an approach built around your company’s unique value proposition. Our sales lead generation approach is non-abrasive and focuses on meaningful conversations with your prospects. Our multi-touch and integrated marketing approach incorporate database updating, email integration, follow up, lead qualification, and drip email for lead nurturing. The more ways you can stay in front of your prospective clients, the better chance you have to close more business. We keep your company on the radar of your prospects!

Key reasons to outsource your sales lead generation efforts:

  • You do not have enough time to make the calls yourself
  • You are great at closing qualified prospects but not generating initial interest
  • In-house callers are underperforming
  • Managing In-house programs can be a real time-consuming headache
  • Save $$$ and reduce overhead
  • Free up your time to focus on improving other aspects of your business

No matter what your specific needs are, Grindstone has a plan and solution for you. Our Sales Lead Generation services will provide you with a constant pipeline of opportunities. Contact us today!
