Purpose Erosion Tracker

Track gradual dilution of investment mission across fund lifecycles

Purpose Erosion: Impact funds rarely fail spectacularly—they erode gradually. Small compromises accumulate: metrics get easier, timelines shorten, stakeholder voice diminishes. This tracker identifies erosion before it becomes irreversible.

Key Insight from SF Theory

Purpose erosion is often invisible until it's too late. Each small compromise seems reasonable: "just this portfolio company," "just this quarter," "just this exit." The cumulative effect is mission drift by a thousand cuts. Regular tracking catches erosion while structural fixes are still possible.
