🌋 After years of being an internet recluse, I’m now bursting with announcements: 1. @castlexyz has been my full focus for >5 years now, and I’m proud to share we recently closed a $15M round led by @khoslaventures to keep pursuing the dream of HyperCard, Flash, MarioPaint et al

I was also crushed to learn this and used the occasion to look through every single work of his: xitter.cf/irondavy/status/191298…
I'm very very sad tonight. I just learned that Stephen Biesty passed away in 2024 at 63... He is one of my favorite artist. Rest in peace.

I used to quote Charles and Ray Eames on this matter: “Innovate as a last resort.” I always got blank stares in response — isn’t innovation the premise of a startup? Yes it is, and this quote does not refute that.

90% of software *should* look and work the same. millions of hours have been wasted by software makers and users trying to create, and figure out how to use, special snowflakes.

Another great one (more io, fewer features tho that's not a bad thing)

I think this game idea is working but I am so bad at it that it’s hard to tell

Math and code are domains of knowledge where experts tend to converge. LLMs making strides in convergent domains does not generalize to divergent domains. I think engineers flatter themselves when they suggest otherwise. Marketing and art, for example, have the reverse nature.

Go work with Mills 👍 and his smart fun team 👍👍 on one of the only social apps that doesn’t make you feel like shit after using it 👍👍👍
I'm hiring a product designer, and perhaps more than one! In the JD, I note that we're looking for a designer "with engineering characteristics," mild hyperbole (perhaps) and definitely one of the stranger phraseological references I've made in a posting. 1/n

Popping up to share something we've been excited about... Castle has a CLI that lets you edit games using models like Claude and Codex. You can create games at lightning speed, then instantly play, tweak, and share them on mobile and web

You might expect the Apple Human Interface Guidelines from 1993 to feel quaint, but even the introduction to the basic concept of a “screen” still hits — we’re doing more “mail slot” software than ever here in 2025!

Very special chance to work in gen AI that isn’t vapid or anti-humane, on a product that’s already working made by a team filled with heart 👇
I’m hiring a product designer for Sudowrite. This is a dream job for a designer who loves to write. The beginning of the listing is… a mini therapy sesh for me. You’d think it’d be chill after that. But no, it goes on to talk about our company cult… sudowrite.com/jobs/designer

The full cycle goes like this: 1. What looks good in a keynote gets shipped first 2. Over the beta they fix the glaring accessibility issues, but doing so dampens how slick the design system is 3. In 1-2 OS releases they find a reasonable middle ground and we forget about this
