Wild: our NPS @ImpulseLabs with customers over the last ~12mo is at 85. (survey had a 25% response rate) Still at zero remorse returns.

Hardware Supply Chain @dessaigne In Shenzhen, a team can go from design to a new physical part in a day. In the US, that same loop often takes weeks, and that gap compounds. The overall stack for rapid hardware iteration still doesn't exist in America, and we want to fund the startups building it.

Austin Justice
Austin Justice@AustinJustice·
San Francisco is now a model for how to fight crime. A few years ago it averaged 86 car break-ins per day. Today: 15. SF did two things: 1. Got a DA that prosecutes criminals: Following the successful recall of Chesa Boudin, DA Brooke Jenkins started prosecuting prolific offenders and said so loudly. Crime dropped every year since she took office. 2. Put tech to use: In 2024, SF activated 400 license plate readers and deployed 80 drones citywide. This tech feeds officers live intelligence on suspects in motion. Drones alone have assisted in 1,000+ arrests since then. The technology lets authorities solve crimes as they happen rather than depend on much more intensive, legally perilous post hoc investigations (which ironically are often more intrusive than using tech). The results: - Car break-ins down 85% - Robbery down 30% - Burglary down 33%. - Homicides hit their lowest level since 1954. Plate readers, drones, a prosecutor who prosecutes. That's the whole formula! Austin has the opposite approach. License plate cameras are effectively banned. Jail bookings are down despite repeat offenders victimizing innocent people regularly. Bond violations went from 37 in 2020 to 250 last year. SF proved crime is a choice. Austin, so far, keeps making a different one.

“One company is converting the OpenClaw demand signal into product. The other is converting it into org charts.” Burn of the year
Aakash Gupta@aakashgupta

Anthropic is building a secure OpenClaw. Four features in 30 days, each one reverse-engineered from the open-source agent that hit 250K GitHub stars and 40,000 exposed machines. The feature mapping is surgical: OpenClaw: text agent from WhatsApp, it works on your desktop. Anthropic: Dispatch (March 17). Persistent thread from phone to desktop. OpenClaw: Discord and Telegram as control surfaces. Anthropic: Claude Code Channels (March 20). MCP bridge to both. OpenClaw: full OS access, browser control, app manipulation. Anthropic: computer use in Cowork and Claude Code (today). OpenClaw: 100+ community skills, no review process. Anthropic: curated plugin marketplace with enterprise admin controls. OpenClaw: heartbeat daemon, always-on 24/7. Anthropic: desktop must stay open. Intentional friction. Runaway prevention. The strategy is legible: let open source take the arrows, ship the enterprise-safe version before anyone else can. OpenClaw proved 250K developers want to text an AI that controls their computer. OpenClaw also proved that desire produces one-click RCEs, CrowdStrike threat advisories, agents creating dating profiles nobody asked for, inbox deletions during “automated cleanup,” and 20% malware rates in skill ecosystems. Anthropic studied every failure mode and built the inverse. Connectors before computer use. Permission prompts before every action. Sandboxed execution. Every constraint maps to a compliance checkbox. Gaps remain. Dispatch requires Anthropic’s own mobile app. OpenClaw works in WhatsApp and iMessage, apps 3 billion people already use. No native messaging integration yet. Cowork needs your Mac awake with Claude Desktop running. No headless mode, no background daemon, no proactive monitoring where the agent messages you first. The “always-on coworker” positioning still requires you to be mostly-on yourself. Here’s where it gets interesting. Steinberger built OpenClaw entirely on OpenAI’s Codex. Said his productivity doubled. Publicly called Claude Opus the best general-purpose agent while building the biggest agent project in history on a competitor’s coding tool. Joined OpenAI February 14. Altman posted he’d “drive the next generation of personal agents” and it would “quickly become core to our product offerings.” Five weeks of “quickly”: GPT-5.4 with strong benchmarks. ChatGPT agent mode in a cloud sandbox. And a March 20 “code red” meeting where leadership concluded product fragmentation was losing them the race to Anthropic’s unified tools. The plan: merge ChatGPT, Codex, and Atlas into one superapp. The core loop Steinberger proved, text from phone, agent works on your machine, you return to finished output, doesn’t exist in any OpenAI product. Their agent runs in an isolated cloud browser. No local files. No persistent desktop control. No async handoff. The person who built the most successful personal agent in history is inside OpenAI. The product that reflects his insight isn’t. Anthropic sent trademark lawyers, then shipped the product. OpenAI sent an offer letter, then called a reorg. The agent race rewards shipping velocity over hiring velocity. One company is converting the OpenClaw demand signal into product. The other is converting it into org charts.

It feels like people don’t listen to proper albums anymore and just let Spotify shuffle for them instead… There’s a certain joy to immersing yourself in a proper album, start to finish. here are my top 5 albums 1. OK Computer, Radiohead 2. Kind Of Blue, Miles Davis 3. I Got Next, KRS One 4. Dark Side of the Moon, Pink Floyd 5. Unplugged, Eric Clapton

I've been hard at work the past few months in SF working on some buy buttons. Today I'm launching my plug-and-play product line that lets you build a robot real fast. Right now to make a robot you have to stitch together a bunch of different PCBs with jumper cables and wait weeks for blackbox actuators to arrive from China. You spend lots of time debugging why your CAN bus isn’t working, why every actuator performs differently, and meanwhile your wires keep coming loose. So, I'm making the following: - RB1: A robot main board powered by an Nvidia Jetson. This handles power distribution, compute, and a bunch more. - WM1: 2-channel wireless radio for sending video/data making the RB1 remotely controllable over USB-C. - M1: A pancake BLDC motor machined in-house. - ACB3: An FOC control board with matching connectors to the RB1. (big brother to ACB v2.0) - A1/A1m: A planetary/cycloidal actuator powered by the ACB3. (this is on the site in a couple weeks) Everything is on sale for this week, and shipping begins this spring! As a big thank you to the supporters of ACB v2.0 (and thanks for patience in shipping delays) you can buy the ACB3 for 50% off. If you like this kind of thing and want to join please DM me, I'm working solo right now and need good folks to join!

“Anthropic’s entire growth marketing team has been one person, for 10 months.” the way bro has been carrying an entire company on his back and using Claude is another level.
Ole Lehmann@itsolelehmann

i can't believe nobody caught this. Anthropic's entire growth marketing team was just ONE PERSON (for 10 months, confirmed) a single non-technical person ran paid search, paid social, app stores, email marketing, and SEO for the $380B company behind claude here's exactly how one human is doing the job of a full marketing team: it starts with a CSV. 1. he exports all his existing ads from his ad platforms along with their performance metrics (click-through rates, conversions, spend, etc) 2. feeds the whole file into claude code 3. and tells it to find what's underperforming. claude analyzes the data, flags the weak ads, and generates new copy variations on the spot this is where he gets clever: he then splits the work into 2 specialized sub-agents: 1. one that only writes headlines (capped at 30 characters) 2. and one that only writes descriptions (capped at 90 characters). each agent is tuned to its specific constraint so the quality is way higher than cramming both into a single prompt so now he's got hundreds of fresh headlines and descriptions. but that's just the text. he still needs the actual visual ad creative, the images and banners that go on facebook, google, etc. so he built a figma plugin that: 1. takes all those new headlines and descriptions 2. finds the ad templates in his figma files 3. and automatically swaps the copy into each one. up to 100 ready-to-publish ad variations generated at half a second per batch. what used to take hours of duplicating frames and copy-pasting text by hand so now the ads are live. the next question is which ones are actually working. for that he built an MCP server (basically a custom integration that lets claude talk directly to external tools) connected to the meta ads API. so he can ask claude things like: • "which ads had the best conversion rate this week" • or "where am i wasting spend" and get real answers from live campaign data without ever opening the meta ads dashboard and the part that ties it all together and closes the loop: he set up a memory system that logs every hypothesis and experiment result across ad iterations. so when he goes back to step one and generates the next batch of variations... claude automatically pulls in what worked and what didn't from all previous rounds. the system literally gets smarter every cycle. that kind of systematic experimentation across hundreds of ads would normally need a dedicated analytics person just to track the numbers from the doc: ad creation went from 2 hours to 15 minutes. 10x more creative output. and he's now testing more variations across more channels than most full marketing teams a $380 billion company. and their entire growth marketing operation (not GTM) = just one person and claude code lol truly unbelievable

Friday night breakthrough. Petpin V0 just ran ~3 hours on a 1200mAh battery under active triggers (motion + audio + camera events) and we’re still sitting at ~78%. Projected full day battery life in this form factor. Power optimization is the product.
