Four-time WNBA All-Star and two-time champion Kelsey Plum is signing a one-year, $999,999 deal to return to the Los Angeles Sparks, per ESPN sources. Plum was in line for the $1.4 million supermax but opted to sign at discounted rate to give the Sparks financial flexibility to build a title-contending roster.

Org Design in the Age of AI I've spent the last few months talking to companies — startups to megacaps — about how AI is changing the way they work. Everyone is adding AI to their workflows. Almost no one is asking why the workflow looks that way in the first place. +++ TODAY Strip a company down and it's three things: people, hierarchy, and information flow. Hierarchy isn't really about authority. It's about information routing — the org is too big for anyone to see everything, so you install managers to aggregate, synthesize, and relay. Meetings, status updates, steering committees, QBRs — all information-routing mechanisms. They exist because moving knowledge between people is expensive. AI makes it cheap. Consider how products get built today. PM writes PRD. Design interprets it into mocks. Engineering interprets mocks into code, estimates "eight weeks," requirements change, PRD gets rewritten. Dev takes months. QA runs regression. GTM preps launch. Mid-sized feature: 3–6 months. The bottleneck was never speed. It was translation cost. PM's intent → document → designer's interpretation → engineer's interpretation → QA's interpretation. Every handoff loses fidelity, requires alignment, generates wait time. AI collapses the translation layers. +++ AI ORG DESIGN PM goes from idea to working prototype in a day. AI generates tests as code is written. An intelligence layer synthesizes customer signals and business metrics in real time — replacing the manager who used to aggregate that weekly. This isn't about each role getting faster. It's the gaps between roles — handoffs, queues, alignment meetings — evaporating. 🔥 Implications: Relay race → basketball game. Small squads, 3–5 people, all skills present, moving simultaneously. Most decisions stay in the squad. Departments → capability atoms. Composable, independent capabilities — collections, identity verification, risk scoring — each combinable with others. PMs become builders. Less time translating ideas for others, more time validating directly. Middle management compresses. The survivors are the ones whose value was always judgment and coaching, not information routing. QA embeds into dev. Quality becomes a guardrail, not a gate. The system generates the roadmap. Jack Dorsey's example: a restaurant's cash flow tightens before a seasonal dip. The system detects it, packages a short-term loan with adjusted repayment, pushes it to the merchant — before they thought to look. No PM decided to build that. The system recognized the moment and composed existing capabilities. Release cycles → continuous flow. Ship daily. Trade big-launch dopamine for relentless, quiet value delivery. +++ The competitive moat shifts from execution speed to learning speed — how fast the org can absorb what AI makes newly possible and restructure around it. Most companies are using AI as a faster horse. The ones that pull ahead will ask: what would we build if we designed this org from scratch today? Full: open.substack.com/pub/robonomics…

Org Design & Reorgs I’ve always been fascinated by two things: 1/ how different companies design their org structures, and 2/ what it signals when a company goes through a major reorg or restructuring. --- 1/ Org structure: no one-size-fits-all Broadly, companies sit on a spectrum from centralized to single-GM. Centralized: decision-making, product strategy, and core engineering are tightly controlled at the center. This works best when coherence matters more than speed - a single system, brand, or architecture where fragmentation creates tech debt or UX inconsistency. Single GM: businesses are run as semi-autonomous units with clear P&L ownership. This works when speed, local optimization, and accountability matter more than perfect cohesion. A. Common patterns > Centralized High premium on end-to-end quality, architectural integrity, and brand consistency. Typical in “one-system” products Examples: $Apple, $Airbnb > Single GM Optimized for portfolios of distinct businesses, categories, or geographies. Speed and ownership beat strict coordination Examples: Common in CPG ( $P&G, $Unilever) and multi-country, regulated businesses (often country GMs, e.g., $Revolut) > Hybrid GM / vertical / geo owners paired with shared platform teams (core eng, data, infra, risk, compliance, brand). This only works if leadership is psychologically comfortable giving up control and pushing decisions down to BU leaders Examples: Marketplaces and multi-line fintechs ( $Uber, $DoorDash, $Robinhood, $Coinbase, $Revolut) B. 180-degree org reversals can happen $Robinhood Centralized → GM-led (2022) Arguably a major contributor to the sharp acceleration in product velocity that followed $Square / $XYZ GM-led → centralized after Dorsey returned A classic response when coordination costs explode, architecture degrades, or brand/system coherence becomes the bottleneck after rapid expansion --- 2/ Restructuring as an investment opportunity Major restructurings often create windows to own good companies while sentiment is messy and execution risk is over-discounted. A few that just/ are going through major restructurings: Meta Googl Shopify Apple SpaceX / xAI / Tesla (potentially)

And splashdown! America is back in the business of sending astronauts to the Moon and bringing them home safely. Reid, Victor, Christina, and Jeremy did an outstanding job. These talented astronauts inspired the world and represented their space agencies and nations as humanity’s ambassadors to the stars. This was a test mission, the first crewed flight of SLS and Orion, pushing farther into the unforgiving environment of space than ever before, and it carried real risk. They accepted that risk for all we stood to learn and for the exciting missions that follow, as we return to the lunar surface, build a Moon base, and prepare for what comes next. And they were not alone. The entire NASA workforce, our commercial and international partners, and the hopes and dreams of people all over the world were with them. The astronauts know it, and you should too. This mission would not have been possible without you. Congratulations. Artemis II, mission accomplished.
