Built for parents and couples who keep meaning to sort this. Sudden walks you through it a bit at a time — your accounts, documents, and wishes — so nothing's left for them to search for.

Built by a solo founder who's asking the same question himself — read why →
Four simple steps. Sudden walks you through everything your family would need — and keeps it private, encrypted, and ready.
Try a sample question below — the same flow you'd use in your real vault. No document to scan, no AI reading your files. Just your answer, encrypted, reminded about, and shared with the right person.
Sample answers, to show how it works — not real user data.
When someone dies unexpectedly, the person left behind has 24 hours to function. Banks to notify. Schools to call. The mortgage lender. The utilities. And most of the time — they don't know where anything is.
This isn't a wealthy-family problem. It isn't an elderly-person problem. It is an everyone-who-loves-someone problem.
This is what the person you love would face. Every step of it is preventable.
Sudden was built for ordinary people who love someone and haven't got round to sorting this yet. Which of these sounds most like you?
If something happened to one of you, would the other know exactly what to do — that evening, the next morning, the week after? Guardian arrangements, school details, financial accounts, the mortgage — all of it.
Sudden gives both partners a shared, clear picture. Sit down together and work through it at your pace — save as you go, and you'll both know where everything is.
If you live alone, there's nobody who automatically knows where things are. If something happened to you, the people who care would be starting from scratch.
Sudden lets you nominate anyone you trust — a sibling, a parent, a close friend — to receive exactly what they'd need. You decide what they can see.
You've been meaning to help your mum or dad get organised. Sudden is simple enough that you can sit with them, work through it together a little at a time, and — on Core and above — print a PDF copy once it's done.
A printed copy can sit alongside their will, so nothing stays trapped in an app they'll forget the password to.
Would your partner know the mortgage lender's name? The life insurance policy number? Who to call first? Most people are surprised by how much they own — and how scattered the information is.
Sudden puts it all in one place — at whatever pace works for you.
Sudden is designed for anyone — including people who rarely use apps. One question at a time. No technical terms. No overwhelming forms. Every field tells you exactly what to write and why.
If you need to stop, your progress is saved. Come back any time. A family member can sit with you to help.
You know you should sort this. The problem isn't motivation — it's that every time you sit down, you don't know where to begin. The blank page is the obstacle.
Sudden removes the blank page. A half-finished vault is already better than nothing — and the readiness score shows you progress immediately.
Illustrative of the situations Sudden is built for — these are not customer reviews. Sudden is pre-launch, so we'll publish verified feedback once families have used it.
"We'd been meaning to sort this for years. We worked through it a bit at a time, over a few evenings. It felt like an enormous weight had been lifted. I finally know she'd be okay."
"I'm a solo ager. I'd been worrying for years about what would happen if something went wrong — who would know what to do. This is exactly what I needed."
"My husband died suddenly two years ago. Finding everything was a nightmare — it took months. I've now done Sudden so my children will never go through what I did."
"For us as working parents, this has been invaluable. We always knew we should sort it. Sudden made it feel possible instead of overwhelming. We chipped away at it over a couple of weekends."
"I helped my mum complete it over two visits. She's 74 and not great with tech — but she managed fine. The questions are clear and it never felt complicated or scary."

Most people who haven't used Sudden are using one of these. Here's why they fall short.
Not a replacement for your solicitor — it's the preparation that makes their job faster (and their fee smaller) when you need one.
Be first when Sudden launches. No commitment — just first access, a launch discount, and the knowledge that your family will be ready.
