Proprietary data is the last software moat standing
You can't clone what you can't see. The data flywheel is the one defense that gets stronger every day you're alive.
What actually counts as proprietary data
Not 'we have a database.' Proprietary data means information that exists because your product is used, that competitors cannot observe or replicate, and that makes your product better in a way users can feel. Usage patterns, outcomes, preferences, benchmarks, correlations — the exhaust of real usage.
The test: could a funded competitor with a great team produce this data without your users? If yes — scraped public data, purchasable datasets, synthetic generation — it's not a moat. If the data only exists because of the specific way your users interact with your product, it is.
Why it's the moat that survives
Proprietary data passes all three moat tests. It can't be cloned — a competitor can copy your UI but not five years of your users' behavior. It compounds — more usage produces more data which produces a better product which produces more usage. And it's invisible — competitors can't even see what they're missing, which means they can't prioritize copying it.
It's also the moat AI makes stronger, not weaker. A model trained or grounded on data nobody else has produces outputs nobody else can match. Every 'AI wrapper' that dies was a wrapper around public data and a public model — nothing underneath.
Key takeaway: Ask what data your product generates that literally cannot exist without your product being used. That's the moat. Everything else is decoration.
How to build the flywheel from day one
Most founders accidentally throw away their moat. They build the feature, log nothing, learn nothing, and wonder why their product doesn't get smarter. The fix is deliberate design: decide what user behavior is signal, capture it, and feed it back into the product where users can feel the improvement.
Instrument the behavior, not just the metric
Clicks, skips, dwell time, re-use patterns — the shape of usage is the moat, not the dashboard number.
Give the data back to users
Recommendations, benchmarks, personalization. Data only compounds if users feel the improvement and stick around to generate more.
Make the loop explicit
On OnlyFoundrs, every click refines the recommendations a visitor sees next. The product literally gets sharper because someone used it.
Never sell or leak the raw asset
The insights can be shared; the raw data is the moat. One careless API and you've handed a competitor your defense.
The domain-expertise multiplier
Data alone isn't the whole answer — it's data plus domain knowledge. The founders getting written off right now are the ones with neither: thin tools in generic categories. The ones attracting attention have deep knowledge of a specific industry and are capturing data nobody else even knows to look for.
If you're picking what to build, this is the filter: a boring niche where you know the workflows intimately will produce proprietary data. A hot generic category will produce a clone target.
Key takeaway: Pick the niche where your usage data is the scarcest asset in the industry. Then build so that every user makes it scarcer.
Ship somewhere your signal accumulates
A permanent listing means your engagement data compounds in one place — instead of restarting at zero every time you switch platforms.
