The conversation that started this. My wife is a psychologist. In her work she sits with people facing the existential questions most of us quietly avoid — illness, loss, uncertainty, and what happens to the people we love when we're no longer here. One evening she asked me something simple. "If something happened to you tomorrow — would I know what to do?" The honest answer was no. Not because we hadn't thought about it. Because thinking about it and doing something about it are very different things. The gap between them — the overwhelm, the discomfort, the "we'll sort it later" — is where most people live. So I went looking for a tool that would let us sit down one evening and work through everything she'd need to know if I wasn't there. Something guided, not overwhelming. Something calm, not morbid. Something that treated preparation as the practical act of love it actually is. I couldn't find one. Not one built for the UK. Not one that took privacy seriously enough for information this sensitive. Not one that felt like it truly understood what it means to leave someone behind. At the same time, I was retraining in software engineering and cybersecurity. That period shaped how Sudden is being built — with privacy, security and long-term trust treated as core design decisions, not features added later. I'm now building Sudden. Sudden is a private digital vault for individuals, couples and families. It brings together everything someone might need to leave clear guidance behind — legal documents, financial accounts, digital access, children's arrangements, personal wishes, even sealed letters. All encrypted end-to-end. All shareable field-by-field. All designed to be completed in one calm, guided evening. Sudden is being built independently in the UK for launch in 2026, with no intention of monetising the deeply personal information families entrust to it. This is the product. This is the point. The need is real. Over half of UK adults aged 50–64 have no will. Tens of thousands of probate applications are filed every quarter. Millions live with low financial resilience. Behind each statistic is a person — or a family — navigating uncertainty they never expected. Sudden is my attempt to make that chaos less common. One vault at a time.
