Accenture Song spent a decade acquiring more than 70 agencies, turning a management consulting firm into a $20 billion marketing engine. That buying spree reached its high-water mark when David Droga sold Droga5 for $425 million in 2019. A year into her tenure as global CEO, Ndidi Oteh is pitching the next phase of the roll-up: a "$1 billion agentic commerce pipeline" alongside the recent acquisition of creator shop Whalar.

Oteh took the top job on the condition that she could "develop and execute on her own strategy" rather than simply steward the creative empire Droga built before stepping into the executive chairman role.

That strategy stacks two distinct agency pitches into one enterprise deck. Buying Whalar gives Song a creator roster to show brand marketers, while labeling the future "$1 billion agentic commerce" reassures corporate finance departments that automated bots will handle the spending. It is the classic consulting roll-up mechanism at work. You collect 70 agencies across the funnel, package their talent as an end-to-end transformation story, and bill enterprise clients for bridging the gap between social feeds and backend software.

The drama inside agency holding companies always comes down to who holds the real leverage. Droga sits as executive chairman while Oteh sells AI agents and creator networks to corporate CMOs. The 70 agencies swallowed along the way exist to prove Accenture can do culture at scale, right up until the automated shopping bots take over the buy button.
