No serious enterprise SaaS company differentiates themselves solely on the product (the products are usually terrible). It's the sales channel, the fact that you know how to bill a big company, the human engineer who is sent on site to deploy and integrate the product, the people on the support line 24/7, the regulatory framework that ensures the customer can operate legally and obtain insurance, the fact that there's a deep pool of potential hires who have used and understand the product. Those are the differentiators.
