NRR used to be the cleanest signal of a healthy SaaS business. 120%+ meant you were in the elite tier - sky-is-the-limit growth. Below 90% meant you were fighting just to survive.

Everyone else sat in the wide middle - 90% to 105% - stable enough to operate, but not strong enough to break out.

But the pattern is shifting fast. And in disruptive times, relying on a lagging metric like NRR becomes even more dangerous.

In CEO roundtables and Impact Academy sessions, I keep getting the same question: “Is NRR still the north star going into 2026?”

Here’s the emerging pattern.

Why NRR Became the North Star

NRR won because it compresses your entire customer engine into one number.

Keep customers. Prevent contraction. Drive expansion.

Simple scoreboard.

But here’s the truth: in an AI-driven industry cycle, lagging metrics lose power. NRR tells you where you ended up - not why, not when the shift happened, and definitely not early enough to correct the trend.

In stable markets, lagging indicators can work. In disruptive markets, they leave you blind.

And we are in one of the most disruptive chapters SaaS has ever seen.

The New Reality: AI-First Companies Break the Metric

In the last 12 months, I’ve met multiple AI-first SaaS CEOs growing 20-40% month-over-month.

Hyper-growth. Explosive activation. Massive user expansion.

But here’s the catch: None of them can calculate NRR in any meaningful way.

They haven’t lived through a full annual cycle. Accounts expand and contract weekly. Pricing evolves constantly. User counts jump by thousands within a quarter.

And there’s another layer: AI-first companies often run on monthly or quarterly contracts. In theory, you can calculate NRR monthly. But long-term value realization still takes time. You need a fuller cycle to understand durable value creation - not just product-led bursts of activation.

So even if they wanted NRR, the metric works against the reality of their business model.

NRR becomes irrelevant - not because it doesn’t matter, but because the business moves faster than the metric can.

At AI speed, lagging indicators collapse.

This is the new pattern.

The Pattern Behind NRR

When you break NRR down, three levers matter:

• Churn

• Contraction

• Expansion

Lincoln Murphy’s Rule of 15s still holds: If churn or contraction is above 15%, or expansion below 15%, that’s your focus.

But in disruptive times, even these signals land late. By the time these numbers move, the pattern was already set months earlier.

NRR and its components give you clarity, but not foresight.

The Real Leading Indicator: Progress

Across every workshop and enterprise engagement this year, the strongest retention signal is the same:

Customer progress.

Not activity. Not meetings. Actual progress.

• More features adopted

• More users added

• More workflows automated

• More business goals verified

• More milestones hit

• More value delivered in shorter cycles

Progress shows up everywhere - product usage data, onboarding steps, AI-driven interactions, support conversations.

It’s the earliest signal of retention. It’s the earliest signal of expansion. And unlike NRR, it updates daily.

I’ve seen teams predict churn with 90% accuracy months in advance just by tracking progress velocity.

This is the leading indicator NRR has been hiding behind for a decade. And it becomes mission critical in an industry moving this fast.

The Real KPI Going Into 2026

In 2025, NRR stopped being the mission. In 2026, it becomes the scoreboard.

The operating metric now is customer outcome velocity - how fast customers reach meaningful, repeatable progress across their lifecycle.

This is where hyper efficient and hyper customer centric finally meet.

Three Rules for Modern CS Teams

1/ Own NRR, but never chase it. It’s earned through daily progress, not quarterly negotiations.

2/ Track the roll-up metrics, but don’t rely on them. They diagnose, but they don’t predict.

3/ Make progress your operating system. Every interaction should move the customer closer to impact.

When progress compounds, expansion becomes inevitable.

So is NRR still the main KPI?

Yes - but only at the end of the game.

In an AI-driven, disruptive era, the leading indicator is the strength, speed, and consistency of customer progress.

That’s what drives retention. That’s what drives expansion. That’s the pattern defining the next generation of SaaS.
