Your family life, quietly handled.
Cosset gives you a dedicated chief of staff, a real person, with clever technology doing the heavy lifting behind them, to take the mental load of running a family home off your plate.
Now onboarding a small number of London families
The feeling
Imagine a Sunday where it's already done.
No mental checklist. The week ahead already handled — appointments booked, forms filed, the thing you'd have remembered at 11pm quietly taken care of. You just get to be with your family.
The mental load
The invisible job
no one applied for.
Renewals, registrations, appointments, the never-ending to-do list, the dates only you remember. Even with a nanny and a cleaner, someone is still holding it all in their head. That someone is usually you.
What Cosset does
One person who holds it all,
so you don't have to.
Your Cosset chief of staff learns how your household runs, then quietly keeps it running. You have one point of contact. We handle the rest, and bring you only the decisions that genuinely need you.
Household admin
Renewals, subscriptions, insurance, bills, paperwork.
Appointments & calendars
Booking, coordinating, and keeping everything in sync.
Travel & plans
Trips, logistics, reservations, the details.
School & activities
Term dates, forms, sign-ups, the family schedule.
Vendors & tradespeople
Sourcing, scheduling, and chasing on your behalf.
Errands & life admin
The small things that pile up.
Cosset works alongside your existing nanny, cleaner, and helpers. We coordinate them, we don't replace them.
Founding families
Join as a founding family.
Our first London families get founding pricing locked in for life, priority onboarding, and a direct line to our founder. Founding places are limited.
How it works
Three quiet steps to getting your time back.
We get to know your home
A thorough onboarding where we learn your household, your preferences, and how you like things done.
You delegate to one person
Hand things over by text, email, or a quick call. No new app to manage.
It just gets handled
Your chief of staff acts proactively and brings you only what needs your decision. You approve anything that costs money.
From the founder
Why I built Cosset.
I built Cosset because I was living the problem.
After years as an investor and operator, and as a mum in London, I watched myself and every capable friend around me quietly drowning in the invisible admin of running a family. Not the big things. The hundred small ones: the renewal that lapsed, the form that was due, the appointment no one booked. Even with help at home, someone was still holding it all in their head. It was always us.
I couldn't find anyone I trusted to truly take it off my plate, properly, discreetly, the way I'd do it myself. So I'm building it: one dedicated person who learns how your home runs and quietly keeps it running, with technology doing the heavy lifting so nothing slips.
Cosset is the thing I wished existed. I'd love for you to be one of our first families.

Trust & discretion
Built on trust, by design.
Letting someone into your household life is a big deal. Cosset is built so you stay in control at every step.
You approve everything that matters
We never move your money or commit you without a yes.
Least-privilege access
We only ever get the minimum access we need, and it's always revocable.
Discreet & confidential
Your family's privacy is the whole point.
GDPR-compliant, insured & accountable
Built to professional standards from day one.

Questions
Anything you'd like to ask.
Do I have to give Cosset access to my bank account?
No. We never take banking logins, and we never move your money. You approve and make any payments yourself; we handle the work around them.
Will Cosset replace my nanny or cleaner?
No. We coordinate and manage the help you already have. We're the layer on top, not a replacement.
How do I actually delegate things?
However suits you. Text, email or voice message. There's no new app to learn.
Is my information kept private?
Yes. Discretion and confidentiality are core to the service, and we're GDPR-compliant and insured.
