Top Matched Vendors
3 open solicitations • National Science Foundation
Vendors whose past work most closely matches National Science Foundation's open pipeline. Every open solicitation is matched against more than four million historical contract records, weighing how deep each vendor's relevant experience runs — the industries they have delivered in and where they have performed the work. Scores accumulate across the entire pipeline, so consistent relevance outranks a single close match.
Matched on each solicitation's NAICS code and place of performance against vendors' award history. This measures who is positioned to bid, not who will be selected.
Recent National Science Foundation Winners
The vendors awarded the most by National Science Foundation from Mar 2026 – Aug 2026, ranked by obligated dollars each month. A vendor holding the top spot every month is an incumbent; gaps and movement are where the competition is.
