ISG is an independent sourcing advisor and market-research house: it helps big enterprises decide what work to outsource, to whom, and on what terms, and it publishes widely-watched index data on the IT-services and outsourcing markets. Its AI bet is a market-structure call, that the old labor-plus-automation outsourcing model is becoming obsolete, and that delivery is moving toward outcome-based contracts built on unified data platforms rather than bodies in seats.

ISG sells advisory grounded in its index data, plus AI-enabled sourcing tooling under the Tango and governance banners, and it has built an AI Acceleration Unit to push data-platform-led delivery, leaning on partners like Databricks. A growing slice of its scope is AI-governance work, advising clients on how to write and police contracts as agents enter the delivery chain, which adds genuinely new billable territory.

The catch is that ISG advises rather than delivers, which insulates it from the labor-deflation hitting the big outsourcers but also caps the upside; it is small-cap with modest, low-single-digit growth. All in, a credible, independent read on where sourcing is heading, and the governance angle is a real new revenue lane, but the firm sells judgment and contracts, not the running procedure itself.
