Why Product-Market Fit Beats email engagement and automation

While Customer.io focuses on email engagement and automation, FitPlum measures what actually matters for sustainable growth: Product-Market Fit.

The FitPlum Advantage:

PMF is the only metric proven to predict both retention and organic growth. Companies with strong PMF (40%+ users "very disappointed" without the product) see 3x better retention and 2x more word-of-mouth growth.
