Product-Market Fit Testing:
Every Innovation Solves a Problem (and Creates a New One)

GAIN vs. NEW PAIN

Whether customers adopt a product isn’t decided by its benefit alone, but by the ratio of GAIN to NEW PAIN.

Every innovation solves a problem and creates a new one. Customers adopt a product only when its benefit clearly outweighs the new effort it takes to use it. Our PAIN-GAIN TEST measures that balance before you invest in a launch.

43% Fail Because of Product-Market Fit

Recent numbers confirm exactly that. A CB Insights analysis from March 2026 looked at the causes behind 431 VC-backed company shutdowns. The finding: for 43%, the real cause was a lack of product-market fit. Running out of money came later; it was only the symptom.

We have developed a simple, universal method that lets you measure product-market fit with your target audience before launch.

The Solution: The PAIN-GAIN TEST

The PAIN-GAIN TEST is a standardized method for measuring the net value customers expect from your product. That net value is what product-market fit really comes down to, and it determines how successful your product will be.

The core idea behind the PAIN-GAIN TEST:

Your product will succeed if the advantages clearly outweigh the disadvantages:

GAIN >> NEW PAIN

The test is grounded in behavioral and decision research. In the Harvard Business Review, John Gourville of Harvard Business School shows the conditions under which innovations actually get adopted.

How to Actually Measure Product-Market Fit

To assess product-market fit reliably, the target audience for a new product evaluates the perceived benefits and newly created drawbacks of using it.

PAIN-GAIN chart with PGI thresholds

The PAIN-GAIN INDEX (PGI) as a KPI for Product-Market Fit:

The PAIN-GAIN INDEX (PGI) is the ratio of gain to new pain. With a PGI above 3, your product has a strong chance of success.

Between 2 and 3, it gets difficult. The product can still succeed if you increase the value proposition or reduce the barriers to use.

Below a PGI of 2, the product is at high risk of failing.

Which Target Group Sees the Highest Product-Market Fit?

In practice, not every customer sees the same value. So the real question is what share of your target group sees enough value.

Specifically:

  • What share of the target group has a PAIN-GAIN INDEX above 3?
  • Which product variant has the highest share with a PGI above 3?
  • Which target group, or which target market, has the largest share of users with a PGI > 3?

The PAIN-GAIN TEST gives you exactly that information.
