Hi, I’m Callum 🙂

Here I am with my wife (Maria), daughter (Mabel), and son (Frank).

Callum Birch and his family.

When I’m not changing nappies, I like to write about business.

A few years ago, I started a brick-and-mortar medical clinic. It was risky. It was a drain on my family. And the rewards were minimal. Nevertheless, the experience was a baptism by fire. And it fuelled my obsession to understand what makes a business successful.

On this website, I share the sawdust of projects I’m working on – including insights on process optimization, high-leverage marketing strategies (like joint ventures), and asynchronous business operations.

I also send emails.

Not a weekly newsletter. Just a personal message whenever I have something interesting to say.

If you’d like, join my email list for more of the above:
