Loneliness is a public health crisis

And it's growing. Millions of older adults live alone with limited daily interaction.

16.6%

Population of New Zealand aged 65+ (2023)

25.3%

Of those 65+, the percentage who live alone

59%

Of older adults feel lonely or socially isolated

Today's technology wasn't built for them

Smart Speakers

  • No long-term memory
  • Not designed for elderly speech
  • No care logic

Premium Companion Robots

  • Meaningful but too expensive
  • Price range: $175 - $9,000+

Apps & Portals

  • Screen-first design
  • High learning cost
  • Low emotional engagement

The Unfilled Gap: There is no scalable solution that is voice-first, memory-driven, affordable, and caregiver-friendly.

Beyond the Numbers: A Countdown to Survival

10.5 hours of absolute silence, the lethal 12-hour "Long Lie", and medication adherence plummeting to 80%... Click to explore our Interactive Data Dashboard based on clinical and sociological reports.

Memory creates companionship.
Affordability creates access.

Continuous Companionship

Remembers people, routines, and preferences over time. Lily becomes a familiar presence, not just a tool.

Emotion-First Dialogue

Designed to be warm, patient, and elder-friendly. Natural conversations without complex commands.

Quiet Wellbeing Signals

Inferred from natural conversation (non-medical). Detects pattern shifts in sentiment, routine, and engagement over time.

Ultra-Low-Cost Model

~$20 device + affordable subscription ($3-7/month). Hardware-as-a-Service makes companionship accessible to all.

Help us ensure no older voice is left unheard

— starting with real pilots.

Our Ask (Next Phase)

  • Guidance on responsible AI and privacy as we prepare for real-world eldercare pilots
  • Introductions to care organizations or NGOs interested in piloting a low-cost voice companion
  • Feedback on scalability and product-market fit as we move from MVP to early deployment

Entering a pilot-ready phase with a functional MVP and multiple iterations completed.
