HeartBuddy
An AI companion for children. Preparing them at home, supporting them in clinic, soothing them in hospital, walking with them through recovery.
See Buddy in Action.
A brief look at how HeartBuddy turns emotional stress into moments of comfort, connection and cooperation.
Each child chooses a buddy, and they start getting to know each other. They talk about their favourite things, hobbies and what makes them laugh. Jokes and stories help the child feel at ease, building trust so they can share what’s on their mind.
The buddy asks about the upcoming procedure and how the child feels, offering reassurance and support with their worries.
For the medical explanation, Mimi steps in. She walks the child through the procedure in simple language, with gentle animations showing what to expect. Mimi answers their questions and responds to their concerns. When they’re ready, the child returns to their buddy to keep chatting and playing.
The care team receives a brief summary of the conversation, highlighting the child’s concerns and any moments that may need closer attention.
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.

Pediatric care has great people.
What is missing is the thread.
Today, every part of the journey has its own answer. Each works in its moment. None connect. The gap is not a missing tool. The gap is continuity.
HeartBuddy is a force multiplier. The CLS gets a presence between visits. The parent gets an evidence-based guide. The hospital gets a continuous emotional record. The child gets one familiar friend across every setting.
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 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.
Two flagship hospitals. Two phases.
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 in pediatric oncology and surgical preparation.
US News Honor Roll - 12 consecutive years. 673 pediatric beds, 17,000+ staff. US validation with international brand partner. Beachhead for enterprise scaling.
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) and Nationwide quantifies the time, staffing, and pharmacological savings HeartBuddy delivers per pediatric encounter - turning anxiety from a hidden cost into a measurable clinical asset.

Common questions.
HeartBuddy includes simple role-play and comic scripts that explain these tools in kid-friendly language. Children can “practice” on the character first, so the real moment feels familiar instead of frightening.
Even in a short 10–15 minute appointment, HeartBuddy can calm a child in the waiting room and prepare them for what’s about to happen, like a vaccine or ear check, so the visit goes more smoothly.
Quite the opposite. HeartBuddy encourages reflection and communication with caregivers, friends, and teachers.
No. HeartBuddy is not a therapeutic or diagnostic tool. It’s a supportive companion to build emotional awareness and vocabulary.
Yes, because it’s not open. Every response is shaped by child-development experts and follows emotional-safety guidelines.
No. HeartBuddy uses AI to recognize emotions and respond, but only within carefully designed emotional flows. All content is age-appropriate and pre-reviewed.
