Zelo Tech · Elder care, reimagined

Care that notices what words can’t.

Older adults often say “I’m fine.” Zelo listens to the quiet signals behind it, so families and caregivers can show up early, with warmth instead of worry.

The story

A day in a life we want to protect.

  1. Meet Dona Lúcia, 78

    She lives alone, and says she’s fine.

    Her daughter calls every evening. Lúcia answers brightly, because she doesn’t want to be a burden. On the phone, everything sounds okay.

  2. The quiet part

    Small changes go unseen.

    More tired mornings. A flatter smile. A moment of confusion over a familiar name. None of it is dramatic, so none of it gets noticed, until it’s hard to ignore.

  3. Where Zelo comes in

    Zelo notices what a call can’t.

    During everyday moments, our technology reads subtle facial-expression patterns and tracks how they shift over days and weeks, always against Lúcia’s own baseline.

  4. The outcome

    Her family knows when to lean in.

    Not an alarm, a nudge: “Mom seems more tired this week. Maybe call earlier today.” Early, human, and kind, with her clinician in the loop when it matters.

Our vision

A world where growing old never means growing unseen.

Populations are ageing faster than caregiving can scale. Families are stretched thin, and the earliest signs of cognitive and emotional change are the easiest to miss. We’re building the attentive, always-gentle layer that helps people care for the ones they love.

  • 01

    Dignity first

    Technology should make older adults feel seen, never watched. Every design choice starts from respect.

  • 02

    Privacy by design

    Sensitive signals deserve the strictest care. We collect the minimum and keep control with the person and their family.

  • 03

    Support, not replace

    We don’t diagnose. We surface early patterns so people and professionals can have the right conversation sooner.

How we address it

Three quiet steps. One caring outcome.

Observe

Computer vision reads subtle facial-expression cues during ordinary moments, with no tests, no wearables and no new habits to learn.

Understand

We compare every signal to the person’s own baseline and follow trends over time, because one off day isn’t a pattern.

Connect

Plain-language updates reach family, caregivers and clinicians, so the right person acts at the right moment.

See it in action

What a gentle signal looks like.

Pick an expression and watch how Zelo translates subtle facial cues into plain, human indicators. This is an interactive simulation of the experience, built to show the idea, not to measure you.

Steady gaze and a relaxed expression, in line with this person’s usual pattern.

Zelo is designed to support, not diagnose. Signals are meant to start a conversation with family or a healthcare professional.

The team

The people behind Zelo.

Engineers, designers and clinicians who have each cared for someone we love, and who believe technology can be tender.

    CEO & Co-founder

    Replace with a one-line story about why this person cares about elder care.

  • Founder Name

    CTO & Co-founder

    Leads computer vision and the on-device privacy architecture.

  • Clinical Advisor

    Geriatrics / Neurology

    Guides how signals are framed so they support, never replace, clinical judgment.

  • Design Lead

    Product & Experience

    Designs for the caregiver at 3 a.m. and the grandmother who just wants to be seen.

Our commitments

Trust is the product.

  • Consent, always

    Nothing is analysed without the clear consent of the person being cared for and their family.

  • Minimum data

    We favour on-device processing and keep only the trends that help, not raw footage.

  • Clinically guided

    Developed with geriatric and neurology advisors, and framed as decision support for humans.

  • Built to be audited

    Fairness across ages, skin tones and expressions is a design requirement, not an afterthought.
