Because NOZA Exact Matching service matches your constituents against the NOZA database of publicly available giving data and also matches the constituent name and address against a national consumer index containing household addresses, your results quickly focus you on individuals that have known gifts.  

Create queries that segment gift amount at a specific level or higher to obtain a list of donors with proven gift capacity.  For instance, you can create your own query that filters on gift amounts of $10,000 and higher.
