## Full page content

Investor Referral Rate (InvRR) measures the percentage of existing investors who generate one or more qualified investor referrals during a defined measurement period. It reflects how actively the current investor base expands the acquisition ecosystem.

 Why it matters

 Referred investors often arrive with a higher degree of pre-existing trust, which can reduce both acquisition cost and time to conversion. InvRR shows whether relationships are being cultivated well enough to generate organic growth.

 How to calculate it

 Divide the number of existing investors who produced at least one qualified referral in the period by the total number of existing investors, then express the result as a percentage.

 What good looks like

 In most cases, a higher InvRR suggests that Relationship Capital and Investor Experience are strong enough to prompt voluntary advocacy. A stronger result may suggest referrals are being actively encouraged rather than left to chance.

 Common failure mode

 Organizations often assume satisfied investors will refer others on their own initiative and never build a structured process for requesting or tracking referrals.

 Relationship to other measures

 InvRR belongs to Relationship Capital and connects to Trust-to-Referral Conversion Rate and Investor Advocate Score, since referral activity is generally a downstream expression of trust and advocacy.
