This scorecard evaluates a business idea across four linked dimensions. First, determine whether the addressable market is large enough for the kind of company and financing being pursued; Leary notes that a lifestyle business can use a different scale threshold from a venture-backed company. Second, test whether the idea addresses a felt pain rather than offering only a mild benefit. Third, examine competition by quality, funding, number, and neglect, not merely by its existence. Active, well-funded startups can make entry difficult, while old or weak alternatives may validate demand and leave room for improvement. Finally, articulate why the new offer is demonstrably better. The output is a decision to investigate further, revise the differentiation, or return to the drawing board.
Origin
Sarah Leary described the criteria her team used while evaluating opportunities during the search that produced Nextdoor. Extracted from The Foundr Podcast.
Core principles
- 01Market ambition should match the financing model
- 02Acute pain creates a stronger adoption reason than mild benefit
- 03Competition can validate demand without making a market attractive
- 04A new entrant needs a clear and demonstrable advantage
How to run it
- 1
Match market size to ambition
Estimate the addressable market and compare it with the intended business model. A company seeking venture capital needs enough potential scale to support that path.
Pro tip Assess scale before years of effort make the choice expensive to reverse.
Watch out Do not impose venture-scale requirements on a deliberately smaller lifestyle business.
- 2
Test the pain
Identify the gap people already feel and the behaviour it causes. Prefer a problem that gives users a reason to adopt something new.
Pro tip Look for existing workarounds or repeated frustration.
Watch out A feature that sounds useful may still lack an adoption trigger.
- 3
Grade the competition
Review who competes, how recently they were funded, how capable they are, and whether incumbents are neglected. Treat competition as evidence with both positive and negative implications.
Pro tip Compare the quality and momentum of rivals, not just their count.
Watch out A crowded field of strong new teams is different from a market served by stale tools.
- 4
State the advantage
Explain in concrete terms why users should choose the proposed product over their current options. If the advantage is unclear, revise the idea before advancing it.
Pro tip Phrase the advantage from the user's perspective.
Watch out Market existence alone does not make an undifferentiated entrant viable.
In the wild
The team found that local connection already happened through Yahoo Groups, listservs, and printed local newspapers. Those alternatives helped validate the need, but Leary's team judged that a purpose-built neighborhood network could offer something demonstrably better. The competitors were not treated as an automatic reason to enter or stay away; their quality and neglect shaped the decision.
→ Competition supported the market case while leaving the team a credible route to differentiation.
Common mistakes
Counting competitors without grading them
A raw competitor count ignores whether rivals are strong, recently funded, or neglected.
Entering without a clear advantage
Competition may validate demand, but the entrant still needs to explain why it is a better option.
Is it for you?
Best for
It is best for founders comparing several opportunities, especially when considering outside investment.
Not ideal for
It is not ideal as a financial forecast or as a substitute for direct customer discovery.

“you got to think about how big is is that market”
“we wanted to find something that was a real pain point”
“you have to be able to clearly articulate why you are a better option than that competitor”
