Beyond just reviewing posted Federal Contract Opportunities, many companies wish to anticipate future opportunities by identifying currently active contract awards that may be re-bid. The common term for this is a Re-compete Opportunity.
The way to identify re-compete opportunities on GovTribe is to search currently active Federal Contract Awards and Federal Contract IDVs that have a completion date in the near future, and that interest you with regard to scope-of-work, set-aside, target agency, etc.
This second video demonstrates how to add Pursuits to your Pipelines in GovTribe - including how to add re-compete opportunities based on Federal Contract Awards or IDVs. (The segment on re-competes begins at minute 6:00 of the video.)
