Ask Rellio what it is, or tell it what you are building. This first conversation will help the page adapt around your context.

Extending human memory

Human memory has limits.

Anthropologist Robin Dunbar famously suggested that humans can typically maintain around 150 stable social relationships.

Whether the exact number is right is not really the point. The principle is.

You can care about hundreds of people. You just cannot reliably remember every promise, opportunity, introduction and follow-up without help.

Modern life asks us to manage relationships across work, family, friends, communities, projects, social media and personal life.

Rellio does not replace human memory. It extends it.

Relationships create opportunities, but modern life makes them hard to remember, prioritise and act on.

06Relationship Capital

Vision

Imagine a world where trust was treated as wealth.

Imagine if relationships were not scattered across inboxes, notebooks, LinkedIn, WhatsApp and memory.

Imagine if the people, promises and possibilities around you became easier to see.

Imagine if technology helped us become more thoughtful, not less human.

As Artificial Intelligence makes information easier to generate, human relationships become even more important.

Rellio is one practical step towards a bigger idea: Human Economics.

The belief that relationships, trust, creativity, curiosity and collaboration deserve to be recognised as serious sources of value.

Social impact

Built to be useful beyond business.

Rellio is being built for founders, professionals and organisations. But it should also serve people working on social and environmental problems.

NGOs. B Corps. Social enterprises. Community projects. Emerging markets. Uganda and East Africa.

The long-term intention is that Rellio will always be more accessible for organisations doing meaningful work, especially where better relationships, better memory and better follow-up can help create real-world impact.

AI and technology should not only make wealthy organisations more efficient. They should help more people solve important problems.

Why I'm building Rellio

I have probably been thinking about this problem for most of my adult life.

Across business, social impact, creative projects, community initiatives and sport, I kept coming back to the same question.

How do we become more intentional about the relationships that shape our lives?

Artificial Intelligence became brilliant at helping me think. I wanted something that also helped me remember, organise, prioritise and act.

That became Rellio.

In the early beta, Rellio is deliberately founder-led. That means you do not just get access to the product. You also get direct access to me while Rellio is still being shaped.

Every beta conversation helps improve Rellio Intelligence.

Private Beta

This is an invitation, not a signup form.

Rellio is still very early.

For now, I am inviting a small number of Private Beta users.

If I have sent you this page personally, it is because I think Rellio could genuinely be useful for the way you work.

You are not just testing software.

You are helping shape Rellio Intelligence while it is still being built.

Developed by The Ideas Shed

Our vision: a world where curiosity and creativity are valued as highly as certainty.

Rellio is one expression of that vision: a product built around conversation, memory, creativity, trust and human relationships.
