Temma wedding donation

Target charity for Tim and Emma’s 2026 wedding. As we celebrate starting our next chapter together, we feel incredibly grateful for the love and support surrounding us. In lieu of traditional gifts, we’ve chosen to celebrate this milestone by looking outward and making a meaningful impact. We’re raising funds for GiveWell , an organization dedicated to finding the most cost-effective, life-saving giving opportunities worldwide. Jueyan Zhang first introduced us to GiveWell’s work, and the more we learned, the deeply we came to believe in their mission. We believe now more than ever that when we come together, we can create real, tangible change for communities that need it most. If you’d like to help us celebrate, we would be so incredibly grateful for a donation to our campaign.

Chloe and Judah's Wedding Donations

As we excitedly celebrate our love for each other, we're also excited to share that love with the world. We will be donating 10% of the value of our gifts to the life-changing work of GiveWell , which identifies effective charities helping people who need it the most. Through GiveWell’s supported programs, each $5,000 donated is estimated to save one life. At this time of joy and celebration for us, it moves us to think that our wedding can also be a way to offer others the gift of life. If you’d like to join us, you’re very welcome to contribute to our efforts by donating 10% of the value of your own gift (or by making a donation instead of a gift altogether!)

    Backing this because GiveWell applies the same evidence-based rigour to charitable giving that we use in health economics. Excited to see what our community can achieve together. - Mirko
