The KPI Mistake Many Startups Make
Jun 11, 2026
Most startups don't have a KPI problem.
They have a KPI overload problem.
I've seen board packs with 40 KPIs, dashboards full of charts, and management teams spending hours discussing numbers.
Yet nobody can answer three simple questions:
- Are we achieving our strategic goals?
- Why or why not?
- What should we do next?
The mistake isn't having the wrong KPIs, the mistake is treating every metric as equally important.
The best startup leadership teams build a clear KPI hierarchy, where every metric has a purpose and links back to a decision.
Start With Your North Star KPI
A mistake I've see is businesses constantly changing their headline KPI.
One quarter it's revenue. The next it's customers. Then it's transactions. Then it's engagement.
Your North Star KPI should rarely change.
It should be directly linked to the strategic objective of the business.
Examples might include:
- ARR or Revenue
- Transactions
- Active Customers
- GMV
The purpose of the North Star metric is simple: Are we moving closer to our strategic goals?
If your strategic goals haven't changed, your North Star KPI probably shouldn't either.
Then Build Your Top 10 KPIs
Once you've established your North Star metric, you need a small group of supporting KPIs. Usually around 5-10 (5 is better).
These help explain what's driving the headline number.
For example, if revenue is your North Star KPI, supporting metrics might include:
- Pipeline value
- Conversion rate
- Churn
- Customer number
- Revenue per customer
These are the metrics I expect to see regularly in board packs, leadership reporting and monthly management accounts
They should remain relatively stable over time because they help explain overall business performance.
Operational KPIs Should Change
This is where many startups get confused.
Not every KPI should stay the same.
In fact, some should change every quarter.
Operational KPIs are designed to answer a different question: Are we solving the biggest problems in the business right now?
For example:
If customer onboarding is a challenge, you might start tracking:
- onboarding completion rate
- time to onboard
- onboarding-related support tickets
If collections become a problem, you may focus on:
- DSO
- aged debt
- collection success rates
These KPIs should evolve as priorities evolve.
The mistake is reporting the same metrics month after month, even when they are no longer helping the business make decisions.
Every KPI Should Have a Purpose
One of my favourite questions when reviewing KPIs is:
What decision would we make if this KPI changed?
If nobody can answer that question, the KPI probably isn't that useful.
KPIs should exist because they:
- drive action
- influence decisions
- identify risks
- measure progress
Not because they look impressive in a dashboard.
One Version of the Truth Matters
This is something I've already been working on in my current CFO role.
One of the first projects I started with our Data and Technology teams was creating a KPI definitions document.
It sounds simple.
But it solves a huge problem.
Because without clear definitions:
- Finance calculates revenue one way
- Sales calculates it another way
- Product has a third version
Then every meeting becomes a discussion about whose numbers are correct.
Instead of discussing what to do next.
We're creating a KPI definitions one-pager that will be:
- shared across the business
- included in onboarding
- used as the single source of truth
Because if people can't agree on the metric, they're unlikely to agree on the decision.
Management Accounts Should Reflect Current Priorities
This is another area where I think finance teams can add more value.
Historically, many businesses produce the same KPI charts every month regardless of what is happening in the business.
Personally, I don't think that's particularly useful.
The strategic KPIs remain the same.
The North Star KPI remains the same.
The top 10 KPIs remain broadly consistent.
But the operational KPIs inside the management accounts should reflect the challenges the business is trying to solve right now.
In my current role, we've already started updating some of the KPI reporting to better highlight the areas we're actively focused on improving.
That makes the management accounts much more useful as a decision-making tool rather than simply a reporting exercise.
The Real Purpose of KPIs
The purpose of KPIs is not measurement.
It's decision-making.
A good KPI framework should help answer:
- Are we achieving our strategic goals?
- Why are we or aren't we?
- What should we do next?
When KPIs become disconnected from those questions, they quickly become noise. The best finance leaders don't build bigger dashboards. They build better decision-making frameworks.
The KPI mistake many startups make is thinking they need more metrics.
Most of the time, they need fewer.
Start with:
- a clear North Star KPI
- a focused set of supporting KPIs
- operational KPIs linked to current priorities
Then make sure everyone agrees on the definitions and understands why the metrics matter.
Because the goal isn't reporting. The goal is helping the business make better decisions.
