TA + key hiring leaders + People/HR + Marketing. Add Finance for ROI and Comms/Legal as needed.

Keep the core group small and outcome-driven. You need: TA (workflow + funnel), hiring leaders (role truth + closing), People/HR (experience alignment), and Marketing (distribution + content ops). Pull in Finance to validate ROI assumptions and Legal/Comms to de-risk claims when necessary. The key is decision efficiency: one accountable owner, clear decision rights, and a cadence that ships assets into hiring fast.
