Most of the time, it doesn’t make financial sense to reinvent the wheel. Here are some of the helpful features in Hubspot for sales and marketing that might not make sense to build into a custom FileMaker solution:
Tracking leads as they view pages on your website
Tracking emails and consolidating under contacts
Setting up meetings when your calendar is open
Tracking web analytics
Getting company marketing information such as annual revenue, owner, number of employees, etc.
(most of these functions require customer interaction with a web site)
