Wellbeing at the heart of grantmaking
Who we are
Bloom is a pooled philanthropic fund enabling high-impact charitable giving and grantmaking with a focus on enabling minds around the world to bloom. We identify and support non-profit organisations we view as doing pioneering work, helping them to scale their missions to improve lives. See our theory of change.
We think wellbeing is at the heart of what matters, and so our grants are aimed at measurably and cost-effectively creating wellbeing and reducing suffering at scale.
Measuring what matters
Bloom utilises a cutting edge evaluation metric to ensure our grants are measurably improving lives:
The WELLBY, or Wellbeing Life Year, is a 1 point improvement in self-reported life satisfaction measured on a 0-10 scale for one individual for one year.
This metric enables us to evaluate and compare radically different kinds of interventions whilst maintaining the same focus on what we think matters most: how people feel about their lives.
