Index Exchange

High Deal-Risk · Constraint Mismatch

Estimated Floor (5 Seats · Enterprise / Custom)Custom Quote (Custom / enterprise pricing)Vendor does not publish a self-serve USD floor on its pricing page; requires sales qualification.Sales-gated pricing vs. $800/mo cap (High quote risk)

Opaque Enterprise Quoting vs. SMB/Mid-Market Budget: Index Exchange does not disclose a public self-serve floor (Custom / enterprise pricing). Buyers with a $800/mo cap face high sales-qualification friction.
Sales-Gated Contract Terms: Commercial access operates on an enterprise transaction-fee framework, where pricing is available on request through tailored enterprise sales quotes based on organizational scale and seats.
Primary Operational Bottleneck: Bid Stream Throttling Overhead: High-concurrency DSP connections face rigorous query-per-second throttling when buyers cannot maintain sustained win rates across high-volume CTV pipelines.

Walk-Away Rule: Walk away if you require transparent self-serve monthly billing or your budget ceiling is under $1,000/mo (Index Exchange requires sales-gated custom quoting).

Negotiation Lever: Demand a 30- to 60-day paid pilot opt-out clause in the Index Exchange order form before signing a 12-month enterprise commitment.
