Hilary Steiner and Duncan Bucknill founded Seahorse in September 2024 to create something they couldn’t find themselves. A better way to support someone living with a neurocognitive disorder, while bringing more clarity, connection, and moments of joy to the journey.

They understand firsthand the gaps in resources, education, and community, especially for those in the “sandwich generation” balancing support for both parents and children.

Seahorse provides accessible, science-based tools and guidance for people supporting individuals with Alzheimer’s disease, related dementias, and other neurocognitive conditions.

Through practical advice and thoughtful support, Seahorse helps you build knowledge, confidence, and resilience, so you can navigate what’s ahead while staying connected to the person you love.

We believe support should be accessible to everyone, everywhere, anytime. So you can spend less time trying to figure everything out, and more time holding onto what matters.

Hilary understands this journey in a deeply personal way.

In high school, she learned that her mother would one day develop a degenerative neurocognitive disorder. At the time, she thought she had time to fix it. Maybe even become a superhero neuroscientist before her mom got sick.

There’s no superhero in this story.

Years later, after a career in economics, policy, and gender equality, Hilary found herself supporting her mom through something complex, emotional, and constantly changing. Not as an expert, but as a daughter trying to make sense of it all.

So she built what she wished had existed.

Hilary co-founded Seahorse to provide the kind of practical, thoughtful support she needed at the beginning of this journey, helping others feel more confident, more supported, and less alone.

Hilary spent over a decade leading evidence-based research and content initiatives at The Economist Group before supporting gender equality projects at the World Bank Group. She is dedicated to ensuring that In Harmony provides science-backed strategies that actually work for caregivers. Hilary lives in sunny Denver with her husband, daughter, and Indy, a not-so-mini Mini Schnauzer. 

Duncan is a long-time friend of Hilary who has a passion for mental wellness and building products and services that make a difference to people’s lives. He is also a recovering lawyer with an MBA from London Business School and lives in San Francisco with his wife, young son, and Pepe, his four-legged best friend.
