In your experience, does hiring more sales reps stimulate growth?

In my experience, only if you have the following:
1. PMF
2. Whitespace
3. Scalable Sales Process
4. Consistent or improving win rate/close rate
5. Effective and efficient ramp
6. Ideal candidate profile, by role
7. Ongoing training and development
8. Demandgen machine, providing 70%+ front of funnel inbound

It absolutely can stimulate growth.  However, bloating the sales organization without thoughtfulness will often lead to layoffs and downsizing as we have recently experienced. 

The effectiveness of increasing sales resources varies depending on several factors, including market potential, market saturation, and the ease of adopting the product. In my experience, having more resources does not always translate to increased sales. It's crucial to implement lead generation mechanisms, allowing sellers to concentrate on promising leads. Prospecting is challenging, even for the most effective sellers, so providing support in lead generation is vital. Implementing inside sales programs and a focused digital marketing strategy can often supplement sales efforts more effectively than simply increasing the number of sellers.

I joined many companies as 1 of many reps AND also was involved in hiring groups of reps at a time. From a numbers perspective, there is "more" happening and therefore often more growth. However, is hiring more sales reps a catalyst for atypical growth - I would have to say no in my own experience. I've not witnesses additional growth from the existing team. Also, there are so many variables to consider that make it hard to provide hard stats. Seasonality, increases and decreases in lead volume...

Not the clearest answer but I hope it provides some perspective
