Hey, Peter here 👋 My "day job" is to help companies build better product experiences, and I've been lucky enough to work with some of the best teams in the world (Klarna, Notion, Google, Pitch...). Eventually the penny dropped: I'm pointing out loads of the same mistakes, again and again. So I started just creating and posting free content in my spare time, which highlights some of the 'face-palm' mistakes in products I use. This became Built for Mars, and there are now nearly 90 case studies up there in total. (Aiming to release 2 per month in 2021). And whilst I've done my 10,000 hours finessing over UX, I'm still learning about how to build—and cater to—a community. So I'd love to hear your feedback, and if you like what I do then you can subscribe to the newsletter for a few new case studies each month. Thanks—I'll be hanging around in the comments today so ask anything (UX related, business-related, meme-related etc.) ✌️ --- ☝️ "This is really similar to 'X' and 'Y'!" Yeah, there are some great resources out there which I love and recommend to companies all the time (shoutout to growth.design, mobbin.design and useronboard.com), but nothing really captured the 'common sense' issues that I find myself talking about every day. So I'd say that's my niche: pointing out UX toothaches that once you've seen, you can never unsee—and hopefully explaining the impact of those issues in a broader context. ^ In a recent user survey, someone referred to me as the John Wick of UX mistakes. Which I quite like. ---

Built for Mars has cracked the UX of a case study itself. Very valuable resources here.

Peter has made his "Built for Mars" UI/UX reviews become the de-facto benchmark for the whole sector. The amount of work he puts in shows with both the quality and quantity of his work being outsdanding.

Amazing resource for UX case studies! In particular, the in-depth analysis of the neobanking space is crucial for anybody who is interested in that space. Bookmark the website and subscribe to the newsletter!

Hands on the best UX resource. The case studies are super in-depth and I always find myself learning something new with each edition.

We literally designed our app after many hours of studying and learning from your content. THANK YOU PETER!

I subscribed instantly when I stumbled upon Built for Mars Case Studies. There is just something about learning through examples and I think the overall industry needs more things like this and less design thinking theory.

I've been subscribed to this newsletter for a few months now and don't regret it a bit. Absolutely love the UX of going through the case study. So intuitive and chill :)

Love all of Built for Mars case studies - easy to navigate, beautifully curated and with lots of valuable information.

Terrific work

looks awesome 👍 i like the way it is structured. yet, why are you building for mars? :-)

Awesome product and resource. Peter’s ability to simplify, summarize, and deliver spot-on actionable recommendations for improved UX that is easily digested and understood is fantastic. It’s a must-have Reference resource for those interested in real-world and current UX case studies!

Built for Mars does a lot a hard work doing research for UX case studies. I read a few and now I'm a great fan. Keep the amazing work going.

this is pretty neat :) Loved the Spotify Group Session UX breakdown

As someone who enjoys reading design case studies, this is great!

Awesome! Do you have an RSS feed?

Built for Mars case studies is a treasure trove. I am in awe by how some of the best companies - in regards to seamless UX experiences - make simple mistakes. It simply proves that UX is a never ending building process. Just like writing, it can always be improved.

Amazing resource with a cool name! Good luck

Really cool product. It will be also really helpful if you could do some cases on the worst UX designs and how to fix them.

Amazing work!! This is so helpful!!
