⬤ What is House of Small?
The evolution of small
This is a space for everyone looking for practical frameworks and tools for building businesses through strategic limitation, not growth-at-all-costs. For those who see intuitively feel that bigger isn't always better for them. For those who see that to address the planetary crises fueled by overproduction and overconsumption, we must find a way for businesses to thrive within meaningful limits.
Our framework, Economies of Small, shows you how to find your appropriate size, protect it, and leverage it to scale impact better - in ways that limitless and growth-obsessed companies can't.

From theory to action
Circular economy, Wellbeing economy, Doughnut economics, Post Growth. You might find the concepts compelling, but where's the business playbook?
Meanwhile, everyone tells you the same thing: grow to have an impact. Scale up. Get bigger. Raise capital. Become a unicorn.
Something's not working. And you know it.
A different path
At House of Small we teach you how to build, own, and run a business that drives genuine change proactively. Not through endless growth, but instead strategic limitation.
We've synthesized 6 years of research into a framework and process revolving around the Economies of Small.
Four advantages emerge when you choose an appropriate size.
