No public feed tells you what sharp bettors are doing. But you don't need one. Exchange liquidity is an accidental confession: if the exchange shows $10,000 available to bet on one side at +110, someone wants $10,000 on the other side at +110.

On peer-to-peer exchanges, that someone is overwhelmingly a sharp, because sharps get kicked off sportsbooks and migrate there. Cross-reference that implied fair value against sportsbook odds and you find mispriced lines.

Diagram 01
The assumption chain
Premise 1
Sharps get limited on sportsbooks the moment they win consistently.
Premise 2
Sharps migrate to peer-to-peer exchanges, which don't limit them (exchange takes a flat fee either way).
Conclusion
Therefore: large orders visible on exchanges are disproportionately sharp money.

The data was public but unused. Everyone else built tools around sportsbook prices. Nobody had framed exchange liquidity as a sharp-money signal.

Scanner cross-references exchange fair value against ~100 sportsbook lines. Any line sitting longer than fair is flagged as a bet.

Selling the idea internally.

Got all leaders in one room, showed ~50 product concepts, made Sharp Money undeniable. That alignment is what unlocked 100% org focus.

I built the first UI prototype myself. The designer had less sports-betting context than I did. Same for the 1-minute launch video — product evangelism works best from the person with the deepest context.
