“Beyond the GiveWell Podcast: Fortify Health’s Lessons from Scaling” by Tony Senanayake

TL;DR GiveWell has published a podcast, looking back on their investments in iron fortification and their 8.2 million dollars grant to Fortify Health in 2021. When the grant was made, the projected cost-effectiveness was 5x cash transfers we delivered and estimated 12x. We want to share what this looked like from the inside. Over three years, our team scaled from reaching fewer than half a million people to more than 20 million, while roadblocks in our government engagement strategy forced a pivot. This post is about what we learned over the last 3+ years of scaling a public health intervention, the mistakes we made and the learnings we hope will be useful for funders, implementers and supporters. We are seeking approximately $1 million over the next two years to unlock the government channel, where we believe the next order of magnitude of impact lies.
