Neither model is universally better.
A dedicated SDR team is usually stronger for complex B2B sales, higher ACV, narrow ICPs, longer sales cycles, and outbound motions that require deep product, persona, and objection knowledge.
A shared SDR team can work for simpler offers, early market testing, lower-volume programs, budget-constrained teams, or companies that need light outbound coverage before committing to a full pod.
The mistake is choosing based only on cost.
