34% of startup failures are due to poor Product Market Fit

How to Validate
Product Market Fit

Having PMF isn't enough. You need to know WHERE you have it and WHO your champions are. A lot of finding product market fit is about whether you understand not just is it working? But do we understand why it’s working?

THE COMMON MISTAKE

Average PMF Hides the Truth

Your overall PMF score might be 35%, but that's just an average. Some segments might rate you 80%+ PMF while others are at 10%.

Without Segmentation

Overall PMF Score:

35%

❌ Mediocre PMF across all segments
❌ Trying to serve everyone
❌ Product feels "fine" to everyone
❌ Nobody loves it enough to tell others

With Segmentation

Marketing Agencies:

82% PMF ✅

SMB Teams:

38% PMF ⚠️

Enterprise:

12% PMF ❌

The 4-Step Validation Framework

Find your champion segments and validate where your PMF is real

1

Segment Your PMF Data

Break down your PMF score by customer type, geography, company size, acquisition channel, and user tenure. Look for segments with 80%+ "very disappointed" scores.

2

Identify Your Champions

Find the customer segments that can't live without you. These are your champions—the foundation of your ICP. They should have 80%+ PMF and show strong retention metrics.

3

Understand Why They Love You

Analyze open-ended feedback from your champion segments. What features do they value most? How do they naturally describe your product? What alternatives did they consider?

4

Validate with Behavior Data

Cross-reference PMF scores with actual usage data, churn rates, and expansion revenue. True champions should show high engagement, low churn, and willingness to pay more.

Key Dimensions to Segment By

Customer Type

Agencies, freelancers, SMBs, enterprise—each has different needs and PMF potential

Geography

Some markets may have stronger PMF due to local needs, regulations, or competition

Company Size

1-10, 11-50, 51-200+ employees often have vastly different product needs

Acquisition Channel

Referrals often have higher PMF than paid ads—shows product channel fit

User Tenure

Compare new users vs. 6+ month veterans—identifies activation gaps

Plan Type

Free, paid, enterprise—each tier should show different PMF patterns

🚨 Warning Signs of Unvalidated PMF

Your overall PMF is 38% but you can't identify which segments love you most

Growth is stalling despite "decent" PMF scores across the board

You're trying to serve too many customer types with one positioning

Your ICP is vague: "SMBs that need better collaboration tools"
