Design frameworks that let regulated teams ship AI-built software that passes review. eBay, Microsoft, Riot Games, Department of War. Free audit: link below.

I'm Jeff. I've run Cartisien, a design and engineering studio, since 2007.

What I post about: AI tools now ship screens faster than anyone can review them. The design rules live in someone's head or a 40-page PDF, so the product drifts.

I write about closing that gap with design rules your agents and engineers can actually check against.

If you lead product or engineering at a software company in a regulated space, follow along. And tell me: which screen does your team argue about most?

"What should the design system team build next?"

In most companies the honest answer is whatever the loudest person asked for in the last planning meeting. Nobody knows which components get used, which get detached in Figma, or which get quietly rebuilt in code.

Heads of product: what does your system team measure, and has it ever changed what they built next?

@datavendor_ai @seeklis Seems like a good idea till it’s not. Wait this is never a good idea.

You do realize how much people despise data brokers.

What a clear vc cash grab this is

[Jeff Witters @JeffWitters]

Is this a surprise to anyone??

🚨 #BREAKING: Bank of America, Chase, Well Fargo, & other major U.S. banks reveal rogue AI agents have been found “living” in customer’s bank accounts.

@atmoio Seriously... right. Like when is a country going to just get crippled from an cyber attack. Security is no longer in legacy systems, that shits gonna be $$$$ to retro too

@svpino models love idioms and gerunds

Although not sad for Getty, but for photography in general if this is a sign for the stock sites to come. Design has changed, advertising has changed and budgets smaller so its not a suprise, but wow.

JUST IN: Getty Images files for Chapter 11 bankruptcy after struggling with mounting debt & growing competition from AI-generated images.

Why do AI agent demos look so safe right up until the agent touches a real user's account?

Is the demo showing what the agent can do, or what the team can actually contain and review?

[Jeff Witters @JeffWitters]

@themgmtconsult Thats the million dollar questions right.. I think there is going to be real channel fatigue coming soon. Most will find one main X, linkedin etc possibly smaller niche communities not infiltrated by AI bots and or 1:1 / face to face interactions.

What are you seeing?

[Jeff Witters @JeffWitters]

"Why is the token called blue-dark-2 when it's green?"

Every new hire asks it in their first standup. It made sense when the brand was blue. Then marketing picked green, and the names started lying. Tokens named for their job, like action or muted text, survive a rebrand. Tokens named after a color don't.

Design leads covering two jobs: how many of your token names would still be true after a rebrand?

@akanksha_j20 Engagement farming has become the norm unfortunately for a lot of founders & instead of building a solid product they want to ascend to guru status

[Jeff Witters @JeffWitters]

@SyloveO Recurring complaints usually point to a workflow that keeps breaking.

[Jeff Witters @JeffWitters]

@pukerrainbrow Retention if you have that issue but fixing sales just buys you more churn if customers keep leaving.

[Jeff Witters @JeffWitters]

@ishratn00ri A coffee break that ends with a SaaS idea is dangerous.

[Jeff Witters @JeffWitters]

@minchoi So who is developing the EMP gun?

[Jeff Witters @JeffWitters]

@sqs Mini-apps beat text whenever the answer is picking from a set. On a compliance tracker we built, the whole design question was how fast one person spots the wrong record, and no chat thread gets close to that

[Jeff Witters @JeffWitters]

@kieranklaassen Proactive work is where I'd want a written list of what it can touch without asking.

[Jeff Witters @JeffWitters]

@theo dude agents are the most toxic interactions sometimes. Its like having a psycho coworker, you know their work is good but shit... talking them is like eating glass.

[Jeff Witters @JeffWitters]

@rileybrown Walking voice sessions work well for me for planning - everything else i have to be in front of a laptop

[Jeff Witters @JeffWitters]

@maurice_build Very cool - some really fun problems in agentic mail
