Word-of-Mouth Growth Engine

This framework focuses on moving a product from "functional" to "remarkable" by identifying the core drivers of customer advocacy and ensuring users actually perceive the value you've delivered.

1. Map Viral Potential to NPS Thresholds

Standard NPS tracking is insufficient; you must correlate NPS scores with actual referral behavior to find your "evangelism threshold."

• Overlay Data: Match individual NPS survey responses to user referral data (invites sent and conversion rates).
• Identify the "Double" Points: At Wise, moving a user from a 6 to a 7/8 doubled referrals. Moving them from 8 to 9 doubled them again.
• Target the 9-10s: True word-of-mouth growth only happens when you move users into the "socks blown off" category (NPS 9 or 10).

2. Identify and Over-Index on Advocacy Pillars

Mining the qualitative comments in your NPS surveys reveals the "Product Pillars" that actually drive recommendations.

• Analyze the Comments: Look for recurring themes in the 9-10 scores. For Wise, these were: Price, Speed, and Ease of Use.
• Ignore the Noise: Many things are "important" (e.g., trust, branding), but only a few things drive advocacy. Focus engineering resources almost exclusively on these pillars.
• Set 10x Goals: Don't aim for 10% improvements. Ask: "What is the theoretical minimum cost/time for this process?" Work backward from that ideal rather than iterating forward from the status quo.
