What’s hilarious is they have an entire blog write-up on “how to build a customer referral program”.
Item #9: “Setup Tracking” From Hubspot themselves:
Regardless of the size of your company (though this is especially relevant if your company has a larger customer base)
you need to have tracking set in place
. 
This will ensure that you don’t miss one detail — for referred accounts especially. You should be tracking:
- Who was referred and who referred them
Good advice Hubspot…can you recommend a CRM that tracks referrals?
