Looking to expense this? Your employee learning budget should cover it

Your manager won't pay for you to feel inspired. They'll pay for decisions they can defend. For PMs, engineers and researchers.
Subject: Can I expense this? (£96 a year) Hi, I'd like to expense a year of Built for Mars. It's UX research library that breaks down how real products are designed, and the psychology behind why some work better than others. Besides learning new techniques and finding ideas, the main benefit is that we could make design decisions on evidence, rather than on whoever argues loudest. i.e., before we change a flow, I can see how other companies have tackled the same problem and why their approach works. Their MCP connects to AI tools like Claude, so every AI-design, or vibecoded wireframe will benefit from the entire library of tips. Instead of being an expensive one-off course, it's £96 for the year (about $130). Designers, engineers and product managers at Google, Spotify and Revolut use it. Here's the link: https://builtformars.com Is that OK? P.S. There's a team plan too, if others would find it useful.
  • In the US, learning budgets are typically $500–$2,000 per person, per year.

  • Almost 50% of employees don’t know what learning budget they have, so it’s worth asking.

  • If your team already pays for AI, this gives it better taste. It's a huge ROI on tokens.

  • Cancel anytime. Plus, if you don’t find 10 ideas in your first 7 days, you’ll get a full refund.

It pays for itself the first time you don't rebuild something

You won't use it every day. You'll use it on the days it matters. In between, it turns up in the tools you were going to open anyway.

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

It doesn't need a habit. It needs a problem, and you've got one of those

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.

A continuous stream of "aha!" moments

A gold mine

The case studies are a gold mine. They help me think more critically when designing and the UX Bites show specific examples of great UX in the wild.

A game-changer

Honestly, it's a game-changer. BFM has a way of making the tricky parts of UX design super approachable and fun to learn. Amazing way to deepen your knowledge in UX design.

Truly unique

The long case studies are truly unique pieces in this industry of fast-paced pop-psychology.

The best learning tool

Probably the best learning tool in my arsenal. The case studies have the right amount of detail with the ux bites being an excellent addition.

Genuinely make me giggle

The case studies deliver a lot of thoughtful insights while genuinely making me giggle.

One of the best

One of the best collections of UX principles out there. There's a lot more to what we do rather than just a polished interface.

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.

- Anna Z

*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.

Billing

Do you offer discounts for students and educators?

Yes, complete this form.

Will I need BFM+ after my 5-week Bootcamp?

Roughly 95% of people who complete the Bootcamp, continue using BFM+ after their 5 weeks.

In fact, once teams work out how to properly use BFM+, it's incredibly sticky.

But you can also cancel anytime from inside your account.

Guessing is free. That's why it's so popular.

If this feels expensive, try guessing for another year. Research after launch is called churn.
