Ro adopted the Bernie/AOC banner for the same reason why none of his tweets get traction & he gets ratio’d every time: he is deeply uninteresting as a person & politician. Say what you want about Mamdani and AOC but they are compelling people & natural politicians; Ro has the charisma of a chalkboard. This forces him to grasp at whatever trendy idea/group he can draft off & leech from. Tech was an easy target for the grift when it was widely popular and a great source of fundraising, now it’s DSA populism as the flavor of the week. He fails to get the love that Bernie, AOC, Mamdani get because he isn’t one of them, just another old rich politician looking for the path of least resistance to power.
I make the philosophical case for tax fairness and taxing billionaire wealth. I welcome an argument on the merits for this new social contract. Read here: open.substack.com/pub/rokhan…

everyone is #1 on their own benchmark. really grateful to @micro1_ai for independently sourcing the real world data and manually correcting the ground truth to produce this evaluation. one surprising takeaway: you cannot take reliability for granted. none of the other benchmarked systems achieved > 95% completion rate. that's a difference you feel in production.
Today we're publishing LongExtractBench, a benchmark commissioned by @reductoai and independently validated by micro1. We evaluated seven production document extraction systems across the same 225 complex enterprise documents. The benchmark was intentionally difficult: documents averaged 358 pages and contained roughly 88,700 ground-truth fields each. Every system was evaluated using the configuration documented in the benchmark methodology. Key findings: • Reducto Deep Extract was the only system to successfully complete all 225 documents. • Direct frontier LLM baselines achieved substantially lower completion rates on long, complex documents. • In this benchmark, dedicated extraction platforms achieved higher completion rates than the direct frontier LLM baselines. • Recall was the clearest differentiator. Precision remained high across systems, but recall ranged from 33.8% to 99.6%, highlighting which systems consistently captured the information contained in long, complex documents. The full report includes the benchmark methodology, limitations, and reproducibility resources. Check out the report and results in the comments below.

When precision matters most, trust the benchmarks and go with the most precise option.
Many companies are #1 in a benchmark they crafted. We worked with @micro1 to create an independently audited benchmark to measure document extraction performance with long documents. The results of LongExtractBench show the nuances companies are likely to find in the real world. micro1 tested frontier models with max reasoning and document processing platforms with their strongest configurations, and found notable precision/recall and completion tradeoffs across most. Reducto’s Deep Extract leads the industry by a wide margin. 🧵

What are the most overlooked companies today that are most likely to produce the next "PayPal Mafia" (ie alum who go on to create iconic bizs)? Not the obvious answers (ramp, mercor, etc)... I'm curious for the non-obvious picks. 👀

10 years ago, saying you want to be good at SEO meant you start investing today and see the fruits of your labor in 1-2 years. Today, it feels like companies are executing on SEO strategies and seeing the results within weeks or months. And no, im not just talking GEO/AEO.

Over the last decade, we’ve built robots that can run marathons, harvest food, and even dance. But robots still aren’t very good at the simple tasks we use our hands for, like unpacking groceries or tying a shoelace. Most rely on simple grippers that aren’t much better than a claw machine. Dexterous manipulation has long been one of the hardest unsolved problems in robotics, but humanoid robots need it to be useful in the real world, from warehouses to homes. The traditional approach to training robotic hands involves collecting data through teleoperated robots, but it’s expensive, slow, and unscalable. @_jaku_xu and @JayLiStanford Li got to know this problem well while building humanoid robots at Tesla, where they had the idea to flip the paradigm: instead of having a human control a robot via teleoperation to train AI, they wanted to get better data from actual human hands. With @proceptionAI, Jack and Jay have built the hand that robots have been waiting for: ProHand. They worked closely with hand surgeons to get the anatomy right, using the latest hardware breakthroughs like “soft,” skin-like sensors and finger actuation that mimics tendons. When they showed ProHand at Y Combinator Demo Day, everyone kept asking them whether there was a human underneath the table with their hand sticking out. They’ve also built a data layer with ProGlove, a sensorized glove that humans can wear to collect real motion data to train ProHands — because the ProHand so closely resembles a human hand, a human can wear the same glove that covers the robotic hand (no robot in the loop required). Proception is officially shipping ProHand and ProGlove to researchers and robotics companies today. I’m proud that @firstround got to lead their Seed Round, alongside BoxGroup and Y Combinator.

If you’re struggling to find PMF just pivot to something data center related and experience the magic of market pull.

Whenever I have personal shit going on, it serves as a great reminder that every person I meet / interact with has their own stuff going on, too. Never hurts to be nice.

This is an incredibly exciting company. H/t @bryantchou and his whole team 🙌
Back in 2013, when I was starting Cover, I was introduced to @bryantchou. I was so impressed by his technical chops and raw intensity that I tried to hire him as our founding engineer. He politely declined to start his own new company instead, called Webflow. But we stayed in touch. I followed his journey at Webflow for the next 12 years, watching him flourish as co-founder and CTO — but also the person who ran sales and marketing during the company’s fastest period of growth. He’s one of those rare engineers who understands the product, the customer and business equally. Today, Bryant is launching Ploy (@ployai), and @firstround is proud to be backing it alongside Y Combinator. Most marketing teams spend more time on operations than creative execution. Bryant felt this pain acutely at Webflow, which some marketers call “measureship” — stitching tools together, building dashboards, chasing attribution. So much of the craft of marketing gets buried in this overhead. Ploy is a marketing platform that treats your website as the hub and all your growth channels as spokes. Agents handle the work end-to-end: designing pages, writing copy and running campaigns. It creates a loop that brings your static website to life, learning from traffic and acting on signals in real time. As agents browse on behalf of users and LLMs summarize your content, your website is the source of truth they pull from. It matters more in the AI era, not less. Hex is already using Ploy for account-based marketing, scaling the creation of personalized landing pages without waiting on engineering. Clay uses Ploy to run programmatic SEO, turning one-off builds into a content engine. Congrats to Bryant and the whole Ploy team. Insanely excited to see where this goes.

TIL Why do companies get fined massively for sending unsolicited texts, but politicians spam all day? Because politicians exploit a legal loophole: if a volunteer manually clicks “send” for each text, it bypasses the TCPA auto-dialer ban. Whichever politician closes this loop hole will have a much higher chance of winning their election than if they just keep spamming our phones… 👀
