Barron's turning a lens on alternative data is itself a signal — this stuff has gone from hedge-fund edge case to mainstream financial press fodder. For sourcing teams, that visibility cuts both ways: more capital and vendor interest flowing in, but also more noise, more me-too providers, and harder due diligence to separate genuine signal from repackaged public data.

The real story, as always, isn't that alt data exists — it's whether any given dataset survives a proper backtest and a pricing negotiation.
