The scorecard evaluates a SaaS company through a connected set of operating signals: revenue growth, net dollar retention, gross margin, adoption friction, switching costs, and exposure to customers that are themselves expanding. Strong retention means revenue from an acquired cohort can increase without repeating the original acquisition expense. Adoption friction may slow headline user growth, but integrations, organizational setup, and accumulated workflows can create durable switching costs. The method also separates business performance from market narratives, particularly when comparisons use products with fundamentally different adoption patterns. The output is a balanced judgment about whether the company can convert early customer-acquisition spending into expanding, high-margin cash flows over time.
Origin
Extracted from Acquired during Packy McCormick's explanation of his Slack investment thesis and the operating metrics behind it.
Core principles
- 01Evaluate several operating metrics together rather than relying on one narrative.
- 02Treat net dollar retention as evidence that existing customers compound revenue.
- 03Distinguish easy user acquisition from durable organizational adoption.
- 04Consider whether customers naturally expand as their own organizations grow.
How to run it
- 1
Establish the peer set
Compare the company with SaaS businesses sharing similar adoption requirements and customer structures. Avoid treating products with frictionless individual adoption as direct operating equivalents.
Pro tip Use multiple peer groups when the product spans communication, infrastructure, and productivity.
Watch out A misleading comparison can make healthy growth appear weak.
- 2
Score growth and retention
Measure revenue growth alongside net dollar retention. Determine whether existing cohorts contract, remain stable, or expand after acquisition.
Pro tip Look at several quarters to distinguish a durable trend from a temporary shock.
Watch out Rapid new-logo growth can conceal weak retention.
- 3
Inspect gross-margin economics
Evaluate whether gross margins leave enough revenue to fund sales, product development, and future cash generation. Connect margin quality to the costs of serving expanding customers.
Pro tip Compare gross margins with businesses using similar infrastructure.
Watch out High gross margin alone does not compensate for poor retention.
- 4
Map adoption and switching costs
Document the setup, integrations, workflows, and organizational participation needed for adoption. Decide whether those requirements create durable embeddedness after the initial friction.
Pro tip Separate beneficial workflow investment from needless onboarding complexity.
Watch out Friction without accumulated customer value is not a moat.
- 5
Test customer-linked compounding
Determine whether usage and revenue rise naturally when customers hire, collaborate more, or add business units. Estimate how much growth can come from existing accounts.
Pro tip Prioritize products adopted by customers likely to grow for years.
Watch out Customer concentration can turn this mechanism into a downside risk.
- 6
Reconcile metrics with the narrative
Compare the operating evidence with the market's dominant bull or bear story. Investigate any disconnect before forming a valuation conclusion.
Pro tip State what evidence would falsify your view.
Watch out Being contrarian is not sufficient evidence that the market is wrong.
In the wild
An investor sees slower user growth than a frictionless video product but finds strong net dollar retention, high gross margins, extensive integrations, and customers adding seats as they hire. The investor treats slower adoption as partly structural rather than automatically assuming weak demand.
→ The company receives a stronger long-term quality assessment than its headline user-growth comparison suggested.
A low-valued SaaS company reports strong new-customer growth, but cohort analysis shows contraction after the first year and little integration into customer workflows. The scorecard reveals that acquisition spending is not creating a compounding installed base.
→ The apparent bargain is rejected because its recurring economics are weak.
Common mistakes
Comparing incompatible user counts
A collaboration platform requiring company-wide setup should not be judged directly against a product that individuals can join through one link.
Treating all friction as a moat
Configuration creates defensibility only when it produces integrations, workflows, or accumulated value customers wish to preserve.
Following the market narrative blindly
A persuasive competitive story can obscure strong operating metrics, while good metrics can also distract from genuine strategic threats.
Is it for you?
Best for
It is best for investors and operators evaluating subscription software with measurable expansion and retention economics.
Not ideal for
It is not ideal for pre-revenue products or transactional businesses without recurring customer cohorts.
From the transcript
“they're the fast the fifth fastest growing company and second best net dollar retention uh up there in terms of gross margin.”
“pretty much any fast growing startup that you can name uses Slack, and as they grow, Slack grows with them.”
