What Is Customer Value Delivery?
You deliver value when you help
customers make progress in their lives.
What measurable customer behavior is
the closest proxy for that âvalue deliveryâ?
If customers absolutely loved your product or service,
how would they naturally behave?
How many of them are behaving like this?
(Track in cohorts, improve over time.)

âTo give people the power to build
community and bring the world
closer together.â
âProvide simple, affordable, secure
and reliable digital payments
toâŚmillions of people around

Three Types Of Key Metrics
North Star Metric Customer behavior that
encompasses the whole funnel or marketplace, and
increments when value is delivered to both customer
and the company.
Key Drivers 1-3 Measured first-order impacts of the
work you do each day to maximise the NSM.
(One of these is your ârate limiting stepâ)
Nuance Metrics Important numbers to watch, maintain
in a range, but not maximise.

What Is Your North Star Metric�
North Star Metric Increments when we deliver value to
both customer and company in a natural way where
customers and company behave as expected.
Simple & memorable for the whole company
Represents the full funnel including new, engaged and
churned users.
Does not change often (e.g. every few years max)
Everyone can connect their work to this number

Example North Star Metrics
MARKETPLACES
Your NSM is typically a transaction where two sides come together.
26. startupcorestrengths.com
Your North Star is a transaction, where two sides
come together (transactions or GMV).
Your Rate Limiter But at any time, one side is the ârate
limiter,â for the whole system, and you need to know
which side.
Your Balance Metric So you need a âbalance metricâ
to understand if, at a given time, in a given geography
or category, you should focus on supply or demand.
Example Balance Metrics:
Auction Close Rate â
What % of auctions result in a sale?
Match rate â
What % of searches result in enough suitable matches?

Key Drivers
Key Drivers are the customer behavior âleversâ
you pull each day to maximize the North Star.
They:
Are controllable customer behaviours.
Select only a few (1-3)
Can be a ratio (e.g. activation rate, signup rate).
Revisit every 3 months.
Each one should have an owner and target.

those levers?

What Is Your Rate Limiting Step
RLS â The one metric that, if improved, makes
the whole system run better.
Look over your key drivers and circle the one
you think is your rate-limiting step.

35. startupcorestrengths.com
What Are Your Nuance Metrics?
Nuance Metrics are important âread onlyâ numbers (watch but
not maximise). Make sure they stay within an acceptable
range.
Many are drivers, but not âkeyâ drivers
Sometimes they are not directly controllable
Helpful if they explain variations in the North Star
Often a âcheckâ number that should stay in a certain range

X Focusing on revenue, not value delivery
X Chasing too many metrics
X Analysis paralysis (e.g. attribution, retention)
X Obsessed with a local maximum
Common
Pitfalls
Data should help us focus, make good
decisions quickly and keep executing.

RECAP:
North Star Metric of Value Delivery, endures over time
Focus on 1-3 Key Drivers, including your rate limiting step,
revisit focus every 3 months.
If pre-PMF, key drivers focus you on fast learning
and fit-deepening.
For retention, figure out your habituation threshold
& work backwards.
Each key driver gets a single accountable person.
Questions for each employee:
Do they understand how their work affects the NSM?
Do they understand their key driver?
Can they make good tradeoffs re. investments of time
and budget, and focus them on the most impactful work?

Your Homework:
A conversation with your CEO, Head of Product, Head of
Marketing, Finance + Analytics. Figure out:
1. Whatâs your North Star Metric?
2. What are your 1-3 biggest drivers of that metric,
company-wide?
3. Whatâs your ârate-limiting stepâ?
Fill them into your KPI Sheet, add some historical data & bring
them to our session next week.
Ask each employee: âHow does your work each day impact
our North Star?â (Check for alignment & comprehension)
Regularly ask each employee or team: âWhatâs the most
important work, and howâs it going?â

If your product is
broken and people
are still using it, if you
have high retention
with a broken product,
thatâs a clear sign you
have PMF.

Key Drivers
Deepen fit through iterative learning loops.
Key Drivers incent deepening fit + validated customer
learning:
1. Strength of fit â e.g. conversion rates, activation
rates, easy to sell, referral rates, retention
2. Pace of learning â experiments run per week
Tips: First validate the need. Look for âlanguage-
market fitâ
