This is an email I sent earlier today to all employees at Coinbase: Team, Today I’ve made the difficult decision to reduce the size of Coinbase by ~14%. I want to walk you through why we're doing this now, what it means for those affected, and how this positions us for the future. Why now Two forces are converging at the same time. We need to be front footed to respond to both. First, the market. Coinbase is well-capitalized, has diversified revenue streams, and is well-positioned to weather any storm. Crypto is also on the verge of the next wave of adoption, with stablecoins, prediction markets, tokenization, and more taking off. However, our business is still volatile from quarter to quarter. While we've managed through that cyclicality many times before and come out stronger on the other side, we’re currently in a down market and need to adjust our cost structure now so that we emerge from this period leaner, faster, and more efficient for our next phase of growth. Second, AI is changing how we work. Over the past year, I’ve watched engineers use AI to ship in days what used to take a team weeks. Non-technical teams are now shipping production code and many of our workflows are being automated. The pace of what's possible with a small, focused team has changed dramatically, and it's accelerating every day. All of this has led us to an inflection point, not just for Coinbase, but for every company. The biggest risk now is not taking action. We are adjusting early and deliberately to rebuild Coinbase to be lean, fast, and AI-native. We need to return to the speed and focus of our startup founding, with AI at our core. What this means To get there, we are not just reducing headcount and cutting costs, we’re fundamentally changing how we operate: rebuilding Coinbase as an intelligence, with humans around the edge aligning it. What does this mean in practice? - Fewer layers, faster decisions: We are flattening our org structure to 5 layers max below CEO/COO. Layers slow things down and create coordination tax. The future is small, high context teams that can move quickly. Leaders will own much more, with as many as 15+ direct reports. Fewer layers also means a leaner cost structure that is built to perform through all market cycles. - No pure managers: Every leader at Coinbase must also be a strong and active individual contributor. Managers should be like player-coaches, getting their hands dirty alongside their teams. - AI-native pods: We’ll be concentrating around AI-native talent who can manage fleets of agents to drive outsized impact. We’ll also be experimenting with reduced pod sizes, including “one person teams” with engineers, designers, and product managers all in one role. In short: AI is bringing a profound shift in how companies operate, and we’re reshaping Coinbase to lead in this new era. This is a new way of working, and we need to leverage AI across every facet of our jobs. To those who are affected I know there are real people behind these decisions — talented colleagues who have poured themselves into this company and our mission. To those of you who will be leaving: thank you. You’ve helped build Coinbase into what it is today, and I am sincerely grateful for everything you've done. All impacted team members will receive an email to their personal account in the next hour with more information, and an invitation to meet with an HRBP and a senior leader in your organization. Coinbase system access has been removed today. I know this feels sudden and harsh, but it is the only responsible choice given our duty to protect customer information. To those affected, we will be providing a comprehensive package to support you through this transition. US employees will receive a minimum of 16 weeks base pay (plus 2 weeks per year worked), their next equity vest, and 6 months of COBRA. Employees on a work visa will get extra transition support. Those outside of the US will receive similar support, based on local factors and subject to any consultation requirements. Coinbase prides itself on talent density. Our employees are among the most talented people in the world, and I have no doubt that your skills and experience will be highly sought after as you pursue your next chapters. How we move forward To the team that is staying, I know this is a difficult day. We’re saying goodbye to colleagues and friends you've been in the trenches with. But here’s what I want you to know as we move forward together: Over the past 13 years, we have weathered four crypto winters, gone public, and built the most trusted platform in our industry. We’ve made it this far by making hard decisions and by always staying focused on our mission. This time will be no different – nothing has changed about the long term outlook of our company or industry. And most importantly, our mission has never been more important for the world. Increasing economic freedom requires a new financial system, and we’re building it. The Coinbase that emerges from this will be more capable than ever to achieve our mission. Brian

this is the most expensive sentence Anthropic will read this year. Someone just shipped a frontier LLM with a 12 million token context window that runs at 5% the cost of Opus 4.7. It's called SubQ. First model built on sub-quadratic sparse attention. Here's why every AI lab should be panicking right now. Transformers check every word against every other word. Double the context, compute quadruples. The labs have known this since 2017. They scaled it anyway and charged you more the longer you needed your model to think. SubQ only computes the relationships that actually matter. → 12M token context with 98% accuracy at full length → 52x faster than FlashAttention at 1M tokens → Runs at under $1.50 per million tokens vs Opus at $15 → Cost scales linearly instead of exponentially Now read this part slowly. Every context window you've ever been sold was a marketing number. Accuracy on every frontier model falls apart past 200k tokens. The labs printed 1M on the box knowing most of that window was decoration. The entire RAG industry exists because the foundation was broken. Vector databases. Chunking pipelines. Summarization loops. Every workaround you've ever built or paid for was an apology for quadratic attention. They weren't clever engineering. They were duct tape on architecture that should have been replaced years ago. SubQ fixed the foundation. The math on every agent product being built right now just changed. Long-context at under 10% of Anthropic's price isn't a discount. It's you no longer paying for the company's mistake. The transformer was the first workable answer. Everyone scaled it so hard nobody wanted to admit it was a local maximum. @subquadratic is the first team to actually ship the way out. Opus 4.7 was the long-context benchmark king. That sentence is now in the past tense.
Alexander Whedon@alex_whedon

Introducing SubQ - a major breakthrough in LLM intelligence. It is the first model built on a fully sub-quadratic sparse-attention architecture (SSA), And the first frontier model with a 12 million token context window which is: - 52x faster than FlashAttention at 1MM tokens - Less than 5% the cost of Opus Transformer-based LLMs waste compute by processing every possible relationship between words (standard attention). Only a small fraction actually matter. @subquadratic finds and focuses only on the ones that do. That's nearly 1,000x less compute and a new way for LLMs to scale.

God sends small children into the world to expose men. you think you are holy until a three year old throws a bowl of cereal at the wall for the third time. you think you are patient until you have not slept for five nights straight, and the baby is still screaming. every half man, is found out by his own offspring. children are judges, sent in miniature to read your verdict out loud. God could have judged us from the throne. instead, he sent us toddlers. more effective

This is actually one of the most optimistic things ive seen. Even though there are a lot of very altruistic logicians in red, there’s still so many “all for one” blue people they still won. Im inspired.
Tim Urban@waitbutwhy

Everyone in the world has to take a private vote by pressing a red or blue button. If more than 50% of people press the blue button, everyone survives. If less than 50% of people press the blue button, only people who pressed the red button survive. Which button would you press?

I've barely been using twitter the past week. I imagine there's been like 10 new agentic breakthroughs that have changed no ones lives but what's been life changing for me is caring much less. I'd like to claim it's discipline, but its more like info burnout 😂

My point is, i don’t think its possible to do everything right as a parent. If someone feels strongly about a particular thing, like praise, and wants to do that part right, thats fine. But in focusing on that, I think there are other parts being neglected. So I think we need to lighten up a bit and just enjoy them. We also cant control who they are, or if they will even enjoy us back.

@atomkirk I think praise is destructive, support is everything. As a child, I didn't want anyone's praise; I wanted the freedom to be busy with what I loved. As life made me more praise-oriented, I started chasing praise at the expense of enjoyment.

For our org, its not about communication, its for ownership. I need people to be the driving force behind orchestrating and accomplishing an objective. I don’t see how AI could replace that yet.
Dan Martell@danmartell

Jack Dorsey just published something that should be required reading for every founder. The premise: the org chart needs to be replaced entirely. And the argument starts 2,000 years ago. For thousands of years, every organization on earth has run on the same logic the Roman Army invented. Small teams report to a leader → Leaders report to managers → Managers report to executives. The whole structure exists for one reason: to route information up and down the chain. That's it. The whole system exists to solve a bandwidth problem. Jack's argument is simple: AI solves it better. Block built what they call a "world model" - a continuously updated picture of everything happening across the company. Every decision. Every customer. Every transaction. Every bottleneck. In real time. No status update needed. No weekly sync. No manager to translate what's happening on the ground into language the executive can understand. When the world model carries the information, you don't need the layers. So they eliminated them. Block now runs on three roles: Individual contributors who build. DRIs who own specific outcomes for a fixed period. Player-coaches who develop people while still doing the work themselves. No middle layer. The system handles coordination. The humans handle the work. I've coached thousands of founders. The number one problem is always the same: information latency. By the time a problem surfaces from your front line to leadership, it's already compounded. By the time a decision travels back down, the damage is done. That lag costs you deals, people, and momentum. And most founders accept it as the price of scale. Block is trying to prove you don't have to anymore. I think they're right. Because the hierarchy was never the point - it was just the best tool we had. The moment something better exists, the layers eventually collapse. This is either the biggest structural shift since the 1850s - or it breaks at scale like everything else before it. Either way - every founder should be asking the same question: how much of your org exists just to route information? If the answer is "most of it" - that's your problem. And your opportunity. -DM

Jonathan Haidt
Jonathan Haidt@JonHaidt·
The Anxious Generation was published two years ago today, in a very different world. Back then, the most common objection I got was resignation: "The train has left the station." "You can't put toothpaste back in the tube." "It's how the kids connect today." Today, the world looks very different. It turns out that if our kids were all on a train and we learned it was heading toward a collapsed bridge, we'd find a way to stop it and bring them safely back to the station. That’s what’s happening now. After the historic verdicts in Los Angeles and New Mexico, today is a great day to reflect on the capacity of people in democratic societies to take action, even when opposing some of the most powerful corporations in history. We're getting access to the courts. We're getting phone-free schools. We're seeing whole neighborhoods letting kids out to play, unsupervised, which is what we older folk all remember as the best part of childhood. So I want to recognize: --The mothers (and, right behind them, fathers) who rose up by the millions and powered the movement. --The farsighted governors and legislators in red states and blue states who have been innovating on policy solutions. --The leaders of a dozen of nations, who are raising the age to 16 for opening social media accounts (with a special shoutout to Australia, for going first). --The teachers and school administrators who had their classrooms disrupted for 15 years, and who are now eager to think through new solutions as screens have taken over and obstructed learning. --The grassroots organizations who have been dedicating their efforts to advocate for all of the above in their local communities. --The millions of members of Gen Z who have been rising up, demanding agency over how they spend their lives in the digital era, and finding better ways to connect in real life. And one final group: the survivor parents--the ones you saw in those pictures of people embracing on the front steps of the LA courthouse. I have met many over the years. I am in awe of their courage and tenacity, their willingness to tell their stories of loss, over and over again, to different audiences, in the hope that no other parent would have to endure what they have endured. At long last, juries and legislatures are hearing you, and are acting. Together, we are calling the train back to the station. Together, we are rolling back the phone based childhood and reclaiming life in the real world. The work continues. If you’re not already involved, join us: anxiousgeneration.com/join

@JonHaidt Funny you think the kids weren't anxious before social media. Communications doesn't fix people who are depressed or anxious or just plain nutty. But blaming communications for those ills is laughably childish, typical since your childish take is so full of anxiety and blame.
