The answer to your question is not one-strategy-fits-all because startups focus on different things. Closing your first 100 customers - why 100? Are you following a formula? The strategy will be the same throughout the sales process, but the most effective strategy will depend on what you are selling. Is your product consumer-facing? Is it SaaS, etc? Having that modicum of information will define your sales model. I have built 3 successful sales teams and I have been number 1 in national (entered the list at number 5) and regional sales. I can assess your sales model and provide a strategy in our first call. From there you can implement or we can work together.
