What we look after

Our family

Four family members, each with its own character and room to breathe.

A china teacup and saucer with a magnifying glass, a wooden chess knight and a stack of handmade paper cards on a wooden table.

CallCasper

Begin at the beginning.

Human, personal support for curious minds. We help you reclaim time, ease overwhelm and find a way of working that suits you, with no shame and no pressure.

  • One-to-one support and guided programmes
  • A community, a self-assessment and a values exploration
  • Not therapy, and not a script

IsoSym

In the making

Ethical and Equitable.

An ethical home for ebooks and courses. Pay once, own what you finish and bank what you don’t, with creators and learners treated fairly.

  • The F.A.I.R. method: Finish, Acknowledge, Invest, Redeem
  • Checkpoints, not tests
  • Aligned and Certified marks for creators

The Curious Brew

Curious things, served in a good cup.

Our newsletter and editorial home: unhurried essays, curious links and small comforts, steeped slowly and sent when there is something worth saying.

  • One deep dive, a handful of links and a few small comforts
  • No promotions and no pressure
  • Written by hand, in plain words
An open handwritten journal with a pocket watch and an old brass key on the page, a teacup and a stack of books by Lewis Carroll behind.

The Warren

Early preview

A warm, quiet place to keep track of things.

A calm place to keep your trails, notes and decisions together, and to see how they connect. It works on your phone or your computer, and what you add stays on your own device.

  • Tunnel Map, The Den and All The Things, three ways to look at the same things
  • No accounts, and sharing only if you choose it
  • Free to try while we test it
How they fit together

A guiding hand, not a spotlight

Each one carries a small line saying who is behind it:
