Capacity tells you the ceiling. Affinity tells you the alignment. Ranking is what happens when you multiply them together and put every funder in your universe on the same axis. It is the dimension that lets a fundraising professional answer the question every staff meeting eventually arrives at: who do we work first this week?
The math of Ranking
Aprize Ranking is the product of Capacity and Affinity, normalized to a common scale across your entire foundation and institutional donor universe. The arithmetic is intentionally simple. A funder with median Capacity and median Affinity scores in the middle of the pack. A funder with top-decile Capacity and top-decile Affinity scores at the top. A foundation with extreme Capacity but near-zero Affinity — one that has never granted to your organization before — scores below the mid-size foundation with strong demonstrated alignment to your mission.
The simplicity is a feature. Complex composite scores tend to lose explanatory power as more variables are layered in. Two-factor scores that fundraisers can interpret in their heads outperform black-box composites in field deployment. Ranking deliberately stays at two factors so that a fundraising professional can defend it to a board chair without a slide deck.
Why a single comparable score matters
Many development operations have multiple scoring systems running in parallel. The grantmaking-capacity screen produces one ordering. The grant-history recency and volume analysis produces another. The prospect researcher's qualitative ratings produce a third. The campaign feasibility study produces a fourth. None of them are wrong, exactly, but they cannot be compared. A foundation that ranks high on the capacity screen and low on the grant-history analysis may or may not deserve a gift officer's Tuesday morning.
Ranking collapses the question. Every funder gets one number on one scale that combines the two dimensions that demonstrably predict major giving: ability and inclination. Sequencing the call list becomes a sort, not a debate.
What Ranking does for portfolio review
The most direct use of Ranking is fundraiser portfolio construction. A major-gift portfolio sorted by Ranking lets a fundraising professional see at a glance whether their team is actually working their highest-leverage names, or whether the portfolio is anchored by familiar names that have stopped delivering proportional return.
The second use is board reporting. "We moved 23 names with Ranking in the top quartile from cultivation to solicitation this quarter" is a sentence that survives a board meeting. "We had a busy quarter" is not.
The third use is opportunity-cost analysis. When a gift officer requests a third meeting with a low-Ranking name, Ranking gives the manager an objective basis for asking what was deferred to make that meeting possible. The conversation shifts from defensiveness to data.
What Ranking is not
Ranking is not a relationship score. It does not know that a foundation trustee sits on your board, that the foundation's grantmaking priorities have shifted mid-cycle, or that your last site visit left an open question. Those are exactly the inputs your relationship system carries that public data cannot. Ranking gives you a defensible starting order; the human work of reading it against relationship context is where the value compounds.
Ranking is also not a pipeline forecast. It does not predict grant size or close probability for any individual relationship. It is a prioritization signal, not a financial projection. Pipeline forecasting belongs in your grants management system, drawing on stage and probability data Aprize is not in a position to estimate.
