Entry
A 6-week data product sprint: pick two revenue or risk use cases, build them on the client's platform, and leave a reusable data-product pattern.. No CAL account team today. Enter through the sponsor's network, Databricks, Snowflake or the client's cloud data platform and a short point-of-view note to the Chief Data Officer.

Deal size$1M–$3M
Pursuit cost$45K
Win probability15%
Estimate: Estimate. Pursuit cost is about 9 person-weeks of account, sponsor and SME time at a blended $5,000 per person-week, including extra effort to win a first meeting without an account team. The entry offer itself is a fixed fee of roughly $110k, or an Accenture investment if the pursuit is contested. The deal range is the 12-24 month follow-on (a data product factory serving the business lines), scaled for a smaller client from a reference range of $5-15M. It is not based on client budget data. Win probability of 15% is a planning assumption for an account without a CAL tier.
