Make A Splash For CASK — Become a Sponsor

You're not just sponsoring a fundraiser. You're fueling the science behind treatments for children with CASK gene disorder — one of the rarest genetic conditions in the world. With eleven active research studies now underway and a neuroscientist who has taken gene therapies into clinical trials now mapping every viable therapeutic path for CASK, your support has never mattered more.

Review our 2026 Splash For CASK Sponsorship Packet for full details on sponsorship tiers and benefits.

Want to make an even bigger impact? Consider joining our End of Year Matching Pool. A matching commitment made now will double every dollar donated during our December campaign — multiplying your gift's impact across our entire global community of 550+ families. Contact us at hello@projectcask.org to learn more.

Ready to sponsor? Here's how:

After selecting your sponsorship level you'll be prompted to choose a payment method. We recommend ACH or cheque to minimize transaction fees. Please note this platform may prompt you for a tip — those funds go directly to GiveButter, not Project CASK.

To pay by cheque, make payable to "Project CASK" and mail with your contact information and sponsorship selection to:

Project CASK PO Box 29 New York, NY 10025

Sponsorship commitments and logo/name must be received by May 31, 2026.

Questions? Reach us at hello@projectcask.org — we'd love to hear from you.
