The Key Drivers for SaaS Success
What Outputs do we
want to optimize?
Growth
Profitability
Cash
What’s so different about SaaS?
Cash Impact of a typical deal
If cash flow is bad for one
customer…
what happens when we grow,
and add many more customers?
Model: slow increase in the no of customers added every
month
Cumulative Cash Flow
The SaaS Cash Flow Trough
“The thing that surprises many investors & boards
of directors about the SaaS model is that, even with
perfect execution, an acceleration of growth will
often be accompanied by a squeeze on profitability
and cash flow.”
Ron Gill, CFO at Netsuite
What’s the impact of faster growth?
When your SaaS business is losing
money at an increasing rate, how can
you tell if the business is going to work
eventually?

Can I make more profit from my
customers than it costs me to

product, what more can we sell

Additional topics that would have been
covered had there been more time
What Metrics should we use to
measure a SaaS business?
We care about recurring revenue
MRR Monthly Recurring Revenue
ARR Annual Recurring Revenue
Driving SaaS Success
Using Key Metrics
Always ask to see Bookings over Time
Entrepreneurs always happy to show their MRR over time. But this
doesn’t tell whether their bookings are growing
Computing LTV
Computing LTV
But if $ Churn is negative,
the formula breaks
Two things at play…
The net result for a single cohort…
When Lifetimes get too long…
We need to take into account:
• Risks to the business
• Aging product
• Changes in the market
• Etc.
• The time value of Money
The Solution:
• Discount future cash flows
Real World LTV Calculator
• Use the spreadsheet provided here:
• http://www.forentrepreneurs.com/ltv/
• Formulae involved:
Understanding Public SaaS Companies
Example Operating Model
Break apart Sales & Marketing
To make it comparable with a traditional software business, eliminate New
Customer Sales, as those benefit the future
Now look at DRR (Dollar Retention Rate)
• Example DRR = 123% (Zendesk’s number)
• The existing customer base with no additional revenue
is growing at 23% annually
• So you have a business growing 23% year-on-year,
generating 20% profit
The Magic Number
• In general, I don’t like the Magic Number
• Hard to explain and understand
• BUT — a public company may not give:
• LTV:CAC ratio
• Months to recover CAC
• So use Magic Number to calculate something roughly equivalent
• First developed by Josh James, CEO of Omnivore
• The key insight - if your Magic Number is:
• Above 0.75 — Step on the gas
• Below 0.75 — Step back and look at your business
• Below 0.5 — business probably not ready to expand
