Don't take my word for it

If features can be knocked together in minutes, taste and thoughtful design becomes the differentiator. Built for Mars doubles down on the human touch.

Nir Eyal (Hooked)

An exceptional resource for learning how to build habit-forming products that people love.
Bing Gordon (Kleiner Perkins & EA)

The completest view of the psychological underpinnings of human behaviour that I’ve ever seen.

Steve Krug (Don't Make Me Think)

I’d never met anybody who looks at usability and UX the way I do until I met Peter. Only he’s smarter.
DHH (Hey! & Basecamp)

What a nice idea! Christopher Alexander would be proud to see patterns collected like this.

Better than expensive courses

Your case studies are hands down the best (and fastest) way I'm learning UX—better than the many expensive courses I've bought.

So fun to read

I've never encountered a UX design blog that is so fun to read. Helpful for understanding the basics and also for experienced designers to stay in the loop.

*chefs kiss

The way you've taken the UX concepts, summarised them, and seamlessly docked them with the case studies and bites is *chefs kiss*.

- Richard Boyd

Entertaining and informative

Entertaining and informative. More memes please.

- Anonymous

Second to none

The depth of insight is second to none - and it is clear that actual thought and serious research has gone into them rather than simply rattling off the standard UX-by-the-numbers tropes.

- Daniel

Insights we can use

BFM+ is an archive of small insights which we can then use in our product.

FAQs

How does the Bootcamp work?

After subscribing, you'll be automatically enrolled in the Bootcamp.

In it, I've curated a series of things to read, exercises to try, ideas to explore and Cheatsheets to copy.

You'll need about 1/2 hours each week.

Is this a UX course?

No, it's categorically not a course.

There are no boring Figma exercises. You won't find yourself spamming "next" to complete random modules.

Instead, it's a structured library of content—but you can dive straight into whatever problems you're facing.

Do you have content on my industry?

Maybe, but that's not how Built for Mars is designed to be used.

You probably already know your industry quite well—this is your chance to look at new references.

Instead of thinking "I'm a bank, so I must do bank things", try approaching problems or topics, such as churn, retention, activation, conversions or user delight.

How often is the library updated

Most days, but you wouldn't notice anyway.

There's already more content here than you'll ever need.

Why don't I just ChatGPT it?

You're here because you already know that although ChatGPT will say 80% of the right things, knowing when / how to use the other 20% is what's important.

Besides, if AI replaces design, taste and human insight is what's left.
