One number for your family's health

When illness hits, you'll know exactly who to call.

Ambulance, hospital, tests, medicines, insurance — handled by real people, end to end. You make one call. We run everything else and keep you updated.

All from one call. You stayed with the patient.
The thing nobody tells you

Illness doesn't just hit the patient. It hits whoever picks up the phone.

~50%

of health spending in India is paid out of pocket — before you even count the leave from work, the queues, the paperwork, and the running between hospital, lab, and chemist. Custos is built to carry that load for your family.

What we do

Three ways we carry the load

One profile unlocks all of it. Set up your family once, and any call covers any of them.

Medical Support

One coordinator runs the whole situation — ambulance, hospital, diagnostics, medicines, equipment on lease, home care — and reports back at every step.

Start with a profile

Diagnostics

Search a test or upload the prescription — we read what's needed, collect from home or the centre, and deliver reports on WhatsApp.

Book a test

Insurance

Have a policy? We file and chase the claim end-to-end. Don't have one? We help you find cover that fits your family — in plain language.

Why Custos

Not another app to manage. A team that manages it for you.

Other services hand you a search bar and wish you luck. We do the running — and remember everything, so you never start over.

Real people, end to end

A named coordinator owns your situation from the first call to the final report — not a different agent every time you ring.

One health record

Every report, prescription, and bill for each family member, kept together — ready the moment a new doctor needs the full picture.

Insurance intelligence

We know what your policy actually covers before you spend — and chase the insurer until the money lands.

Nothing slips

Follow-up tests, refills, claim deadlines — we track them so they don't fall through the cracks during a stressful stretch.

Stories from families

The families who handed us their hardest days.

Real situations across Kolkata — when the calls, the queues, and the paperwork piled up, here's what it was like to have Custos pick up instead.

A caregiver sitting with an elderly family member
When my mother had a stroke, I was at work two hours away and completely frozen. I called Custos and within minutes an ambulance was on its way and a hospital bed was confirmed. By the time I reached, the pre-authorisation was already filed and a coordinator was waiting to brief me. They carried the whole weight so I could just be her son.

What families say about us.

Honest words from people we've helped across medical support, diagnostics, and insurance.

Baba was admitted at 2am and I was alone at the hospital. One call to Custos and the coordinator handled the bed, the deposit, everything — while I just sat with him.

I uploaded Ma's prescription on WhatsApp at night. By morning they'd collected the samples from home and the reports were back in the same chat. No queues, no running around.

Our claim had been stuck for weeks. Custos took over, chased the insurer, and the money was settled before discharge. I didn't make a single phone call.
