Reads the teaser. Waits for the CIM. Matches them when it lands.
Anonymized teasers arrive constantly, and when the full deal document finally shows up weeks later, someone has to remember which teaser it belongs to and manually reconcile the two before the deal record is complete.
Celeste reads each teaser as it comes in, stages a new deal record, and later matches the full deal document back to the right teaser using a fingerprint built from sector, size, and geography. It enriches the deal record and writes an investment committee summary.
You get one clean deal record, not two documents to reconcile.
