Finance types worship at the altar of the Bloomberg terminal. So when AI evangelists recently declared it ”cooked,” it was war. 😀https://t.co/IEoS5sku0a via @WSJ

2025 was a big year for @ServeRobotics. We grew our fleet 20X! We now operate in 20 cities across 6 major metros, reaching 3.75 million people, and serving more than 4,500 restaurants (10x growth).

I’m truly proud of what our team has delivered. Our progress was reflected in our Q4 results. Quarterly revenue increased 400% YoY and we exceeded our full year revenue guidance.

Our AI flywheel is working, our platform capability and market opportunity has expanded to hospitals, and we’re just getting started!

I’m about to jump on our earnings call now, and I have a lot more to share about what we achieved last year and our vision for this year. See you there.

@EpsilonTheory @jradbo Looking good, guys!

This is the first AI cut.
And it will send shockwaves.

Remember: Jack is one of the greatest founders of all time. He created this platform that we’re all on, and has been early to many technological shifts. And Block was doing very well as a business.

So, for him to cut 40% of headcount in this way is a signal to everyone in tech: get good now. Become indispensable. Work nights and weekends. Learn the AI tools and raise your game. Or you might not make the cut, as an employee or as a company.

I know. That sucks. But capitalism is natural selection. The market is unforgiving, because you are the market. After all, it’s not like you’re buying some random gallon of milk from the store; you’re always buying the best product at the best price.

So too for apps: your customers are always installing the best piece of code they can get. And because AI is going to create new winners, if you aren’t the best in your market, someone may become better with AI. Particularly with the new agentic workflows.

To be clear: Block’s severance is generous by any measure. 20 weeks of pay, six months of health insurance and vested equity, all of that goes far beyond any typical package. Jack did his level best to cushion the disruption. The laid off are a temporarily unfortunate class, as opposed to a permanent underclass.

But had he not leaned into the AI transition, he might have had to lay off more people, slowly, and over time, as faster competitors went after his market share.

How would they do that? Sure, AI isn’t a panacea by any means, but the closer you are to software engineering the more aggressively you need to embrace agentic workflows. The AI companies are already doing that, and places like Stripe, Shopify, Coinbase, and now Block are pushing hard on this area.

There will be overcorrection. But the fundamental technical innovation is real. And you need to either disrupt yourself or get disrupted.

We @PosthocSalons ran a poll of 5000 people- HOW TRUSTWORTHY IS THAT CEO? Where would you trust a CEO more? Media interview? live event? In an ad? Didn't expect these results - 19% trust CEOS in the media. 18% trust CEOS in an ad. Live journalism, hullo. https://t.co/8GZqK6sK87

@alexrkonrad Pay-to-play rankings are the fastest way to erode brand integrity. There is no way the sponsorship dollars justify the loss of public trust. I've never understood the strategy here.
