Who each product is really for
Teamgate
Teamgate is generally positioned as a sales CRM with a strong analytical bent, aimed at small and mid-sized teams that want pipeline management alongside insight into what is actually driving results. Smaller vendors often compete on closeness to the customer and willingness to help with setup, which can matter more to a twelve-person sales team than the size of an app marketplace.
Pipedrive
Pipedrive is one of the most widely adopted pipeline CRMs, built around activity-based selling: every deal should have a next action, and the interface pushes reps towards scheduling one. Wide adoption brings a large integration ecosystem, plenty of independent documentation and a deep pool of people who already know the product, which lowers the cost of hiring and onboarding.
