I believe salespeople move the world. I play my part by opening doors for them.
To achieve this, we deploy a pull strategy (as against a push) so the right people are keen to learn about your offering, because they want to (rather than because you pursued with persistence or worse: tricked them into saying a yes, temporarily).
Services provided in Sales Development:
1) Account Based Sales Opportunity Generation, and
2) Manual Contact Data Generation (service 1 includes this by default)
