Laying the Groundwork for a National Impact Investing Marketplace
Bibliographic record
Abstract
The practice of impact investing is rapidly gaining momentum, but the level of activity among individual and institutional investors, including philanthropists and foundations, has barely penetrated projections of market potential. The marketplace that should connect impact investors with investees or social ventures does not function effectively. Developing cost-effective ways to engage new investors and break down barriers to investment is an essential part of growing the industry. Developing cost-effective ways to “prime the pump” for social ventures to become investor-ready — through a capacity-building process that includes outreach, education, and technical assistance — is an essential part of growing the industry. The Impact Finance Center partnered with foundations and other investors in Colorado to create “CO Impact Days and Initiative” to demonstrate how to address this need for a more efficient and effective marketplace. CO Impact Days and Initiative was designed to expand regionally and be replicated.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
