The Happiness Lab 2024 charity fundraiser

Support GiveDirectly and your personal favorite charity!
This holiday giving season, Giving Multiplier and GiveDirectly have teamed up with The Happiness Lab to boost your donations!

Choose your personal favorite charity (any US-registered nonprofit), split your donation with GiveDirectly, and earn bonus matching funds on top — it's that easy!

Why GiveDirectly?
GiveDirectly lets you send cash directly to some of the world’s poorest people — no strings attached. Your donation delivers life-changing funds to families, empowering them to meet their needs and shape their futures.

Why Cash?
500+ academic studies show cash transfers can boost income, health, education, gender equity, local economic activity, and more. Giving cash works because it gives families the agency to meet their individual needs and decide how to build their own futures. 

Your donations will help reach people like Twiringiyimana, a farmer in Southern Rwanda. He struggled to support his family on the $1 a day he earned working on others’ farms. His family had no other source of income, and often ate one meal per day.
"With the first part of the cash transfer, we bought essential household items we lacked and clothes for the whole family. With the second, we bought a piece of land for $500. On this land, we plan to start a tree tomato farm, which will help us generate income and save for the future.”
Your donation can help families like Twiringiyimana’s lift themselves out of extreme poverty.

Last year, Happiness Lab listeners helped donate cash to all 193 families in Kibobo village. Here’s how they spent your donations:



500+ rigorous academic studies show just how effective cash can be across diverse outcomes like:
  • 📈 Boosting local economies by 2.5X for every cash transfer
  • 👶 Reducing mortality rates for mothers and babies by 46-70%
  • 🍛 Improving families’ food security and nutrition (even more than a nutrition program)
  • ⏰ Creating lasting financial gains, even 12 years later
This holiday season, give with your heart and your head. Support the causes personally meaningful to you and GiveDirectly, an evidence-based, highly cost-effective charity.

Watch how families can use cash to improve their health:
