Our Story

Why we founded Impactive.

Stewardship has become a critical part of responsible investment.

Yet many organisations still rely on spreadsheets, fragmented data and manual processes to manage increasingly complex programmes.

Having worked in stewardship ourselves, we experienced these challenges first-hand.

We founded Impactive to build technology specifically for stewardship. Not adapted from another industry. Not designed as a generic workflow tool. Purpose-built to help organisations manage engagements, access intelligence and strengthen oversight more effectively.
