A startup must start with a vision, which leads to
strategy, which leads to product
 VISION – this is your overall goal to create a
world changing business
 STRATEGY – business model, product
roadmap, positioning, customers, etc
 PRODUCT – your offering to the customer

Break strategy down into 1 or 2 most important
assumptions – Leap of Faith assumptions
...
The typical leap of faith assumptions are1
...
GROWTH HYPOTHESIS – How do new
customers discover the product? What
growth engine will you use? (see Learn
section)
 Go and see for yourself - What problems do
customers have? Talk to them! Create a
“Customer Archetype” to which daily decisions
can be aligned
 Always test the riskiest assumption first
...

 Types of pivots
o ZOOM-IN PIVOT – A single feature in a
product becomes the whole product
...

o CUSTOMER NEED PIVOT – As a result of
deep customer knowledge it is clear that
other related problems are more important
than the original problem
...

o MONETISATION PIVOT – A change in the
way customers pay for the product
...

o ENGINE OF GROWTH PIVOT – A change
between viral, sticky, or paid growth models
...
For
example consumer goods are sold in a
grocery store, cars in a dealership,
enterprise software by consulting firms, etc
...


 Figure out what we need to learn (hypothesis), then figure out the simplest product that will work
to prove or disprove the hypothesis - a MINIMUM VIABLE PRODUCT (MVP)
...

o Lacks many features (that may prove essential later on with mainstream customers)
...

o Can range in complexity – can simply be a “smoke test” (just an advertisement or website
taking pre-orders to see who bites
...

o When in doubt, simplify! Remove any feature, process or effort that doesn’t contribute
directly to targeted learning
...

o Once proven you can scale knowing there is value and it’s a desired product
o Can validate “Growth Hypothesis” systematically- if using paid model, see if cost of
acquiring and serving customers is less than revenue
...

o Need to find the EARLY ADOPTERS for first customers
...
Early adopters have the greatest need and are more likely to tolerate mistakes
...
This applies to MVP, but also company
infrastructure, processes and the company training/induction manual
...
Additionally, a defective product or process used as a starting point it’s a shaky foundation
to build upon
...

o Try to build in smallest possible batches
...

o An example is sending 100 letters
...
However the quickest way may be to
complete one full letter and envelope at a time
...
What if
they don’t fit in the envelopes? Or 100 envelopes are packed and they don’t seal?
o Doing it one at a time is faster when uncertain
...
Plus one
complete product is shipped every few minutes, rather than all at once at the last minute
...
Metrics need to
be Actionable, Accessible and Available
o ACTIONABLE - It should be obvious based on the results what action must be taken
...

o ACCESSIBLE – Make reports as simple as possible
...

o AUDITABLE – Data must be credible to employees
...

 Collect customer feedback data using COHORT ANALYSIS
...

o For example, one cohort may be customers that signed up to version 2
...
The next
cohort may be customers that signed up to version 2
...

o This simplifies comparisons
...

o Using gross accumulative numbers is referred to as “vanity metrics”
...

o These graphs have the same data
...
So we can say “with version B01, customers showed this behaviour”
...
This allows tuning while
limiting bad press if something goes wrong
...
One group of customers is split randomly and
exposed to either option A or options B
...

They are much more demanding and less tolerant of
 VALIDATED LEARNING –

o Validated by empirical data collected from real customers
 Growth from customer actions has 4 primary modelso Is created by offering something to customers and

This can be through subscription such
o TUNING – experiment with changes in the product
as payTV, or through voluntary repurchase such as

o If after a pivot the tuning activities are more productive,
 Companies using the sticky engine must track their

The churn rate is the fraction
of customers who fail to remain engaged with the product
...
If the
rate of customer acquisition exceeds the churn rate, the

you’re asking, you’re not there yet
...
If the
customer acquisition metric is good, but the churn metric
is bad, focus needs to be on retaining customers
...

 The viral engine is powered by the viral loop - determined
by the “viral coefficient”
...
1 means 1 in every 10 customers
will bring 1 friend
...
1: 100 + 10 + 1 = 111 total)
...
0 will grow exponentially (100
new customers at 1
...

 Companies must focus on increasing the viral coefficient
...

o PAID – Paying for advertising or staff to sell the products
...
So if
it costs 80c average for every new customer, and each
brings $1 of revenue, 20% of the revenue (marginal profit)
remains to reinvest in acquisition
...

 To increase growth rate: Increase LTV, decrease CPA
...

Your product needs to differentiate itself to stay ahead,
and/or target a different demographic

For example company A currently has 5%
growth and company B has 10%
