How do I see product-market fit across my portfolio?

When your portfolio companies measure PMF in PMFtracker using the Sean Ellis survey, you get a standardized PMF score for each one, tracked over time, in a single portfolio dashboard — so you can compare companies on the same 40% rule instead of each founder's own metrics.

What is a good PMF score for a portfolio company?

On the Sean Ellis test, 40% or more of users saying they'd be 'very disappointed' without the product indicates product-market fit. Above 50% is strong. The trend matters as much as the number — a score climbing toward 40% is a strong signal even before it crosses.

Every founder claims traction. None of it compares.

The update is always the same: "traction's great." But ask three portfolio companies how they measure it and you'll get three different answers — signups here, a hockey-stick chart that's really paid acquisition there, a wall of happy-customer screenshots somewhere else. You have no apples-to-apples way to see which companies have real demand and which are running on hope.

And "no market need" is still the number-one startup killer — it ends around 42% of startups. The cruel part is when you find out: usually after a company is already out of runway, when the data that would have flagged it months earlier was never being collected.

You can't manage a portfolio's product-market fit if every company measures it with a different ruler.

One score. Every company. Tracked over time.

PMFtracker puts every portfolio company on the same instrument — the Sean Ellis 40% test — and rolls it up for you.

Standardized PMF score

Every company measured on the same Sean Ellis 40% rule — the methodology used by the likes of Superhuman and Nubank. Finally, apples to apples.

Portfolio dashboard

Product-market fit across all your companies in one view. See where each one stands at a glance — not buried in a dozen different decks.

The trend, not a snapshot

PMF is a number that moves. Watch which companies are climbing toward 40% and which are quietly sliding — quarter over quarter.

An early-warning signal

Spot a stall while there's still time to help — instead of discovering it in a down-round conversation six months too late.

How it works for your portfolio

It runs on the same simple loop your companies already need — you just get the roll-up.

1 · Companies measure

Each portfolio company runs the Sean Ellis survey in PMFtracker on its engaged users — the score is calculated automatically on the 40% rule.

2 · You see the trend

Standardized scores roll up into your portfolio view, tracked over time — one consistent number across every company.

3 · You act earlier

Double down on the companies pulling ahead, and dig into the ones sliding — with data, not a gut read from the last board call.

Sharper diligence. Better portfolio support.

Diligence on evidence

For new deals, ask for the PMF trend, not the pitch. A rising Sean Ellis score with a clear ICP is the hardest signal to fake.

"The 'Sean Ellis score' is a key element of how Nubank measures product-market fit and makes decisions about investing in new products. The score is based on asking customers, 'How disappointed would you be if this product went away?'"
