HeartBuddy
An AI companion for children. Preparing them at home, supporting them in clinic, soothing them in hospital, walking with them through recovery.
Half of children
walk into care scared.
Pediatric anxiety is the most under-addressed problem in children's healthcare. It starts at home, peaks in the clinic or hospital, and follows the child home. Every system in the chain feels the cost.

The Engine of Science.
The Face of Magic.
HeartBuddy is a vertically integrated AI platform that connects the clinical journey with emotional continuity, turning a scary medical process into a familiar adventure.
One engine. Many faces.
Israel pilot launches with Cramel - Israel's #1 children's brand. US commercial launches with an international partner: active discussions with Disney and Sesame. The engine is brand-agnostic. One engine, many beloved faces.
One companion.
Four moments.
HeartBuddy is not a hospital tool. It is a continuous presence. It meets the child wherever care is happening - whether that is in a children's hospital, a pediatric clinic, or a quiet bedroom the night before a procedure.
Meet Buddy at home. Kid-level explainers, role-play, worry decompressed before arrival.
Check-in, mini-games, breathing cues. Real-time mood signals to clinicians.
Daily check-ins, bedtime stories, mood tracking for nurses and Child Life.
Home after discharge. Bravery badges, emotional check-ins, family-subscription continuity.
A flagship children’s hospital. Real clinical proof.
HeartBuddy goes to market on clinical proof, not promises. Validation launches in Israel first with a local IP, then scales to the US with an international brand partner.
The children's hospital of Sheba Medical Center, ranked 7th in the world (Newsweek 2026) and Israel's number one for eight straight years, a global oncology leader with its ARC innovation ecosystem. Clinical research launches here with Cramel in pediatric oncology and surgical preparation.
Proven where care happens.
HeartBuddy accelerates pediatric care and reduces hospital resource consumption. Children prepared by Buddy complete procedures faster, require less sedation, and need fewer staff interventions. Our clinical research at Safra (Sheba) quantifies the time, staffing, and pharmacological savings HeartBuddy delivers per pediatric encounter - turning anxiety from a hidden cost into a measurable clinical asset.
