In the U.S. & around the world sales pro's earn multi-six & 7-figure incomes (Read: more than most physicians, attorneys, engineers, etc.), yet most founders fail to recognize their import. For example, startups regularly task a co-founder or, gulp, initial admin hire to engage a prospect list or subset thereof. It is an enormous mistake that yields suboptimal adherence to best-practice and crucially, a flawed data set that a founder may clumsily use to forecast growth, churn etc.
The sales talent required to build processes, identify most promising inbound/outbound prospect funnels, execute script/price-point analysis & closing ratio's, etc. to bring a v1 to market is immense. Respectfully, your friend is woefully unqualified to serve your startup well. A B2B with pricing model you've suggested requires a 10x pro.
