Engagement
Early reading. We have captured 2 original posts for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.
A typical post picks up 709 interactions against 263K followers, an engagement rate of 0.271%. Posts are seen about 149K times each, and 0.477% of those impressions turn into an interaction. That is about 56.4% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.43 posts a day over the last 30 days, though only 33% of days saw any activity at all. Most posts go out around 16:00 UTC, and Monday is the busiest day of the week. Of the 2 posts sampled, 100% carry an image or video. The account's strongest tracked post pulled 2.5K interactions, about 3.5x its own typical post. Only 2 original posts have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.

Posting timing
This account posts most often around 16:00 UTC, and Monday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 100% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 0% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 100% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 0% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 252 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

Introducing @PoeticHQ: a new AI system that executes complex multi-hour tasks with 99%+ accuracy and 10x fewer tokens than agents. We raised $50M at $500M from Kleiner Perkins, Founders Fund, First Harmonic, and Genius Ventures to build AI that does complex work inside Fortune 500 companies without hallucination. While code is too brittle, agents are too unpredictable. The work that runs the global economy - anti-money laundering, fraud investigations, underwriting - needs extreme accuracy. So we built a new kind of software that pairs the flexibility of AI with the predictability of code. When the world stays the same, Poetic runs fixed code: fast, cheap, identical every time. When the world changes, Poetic uses AI to regenerate its approach and find its way back to the objective. In one year, we went from zero to an eight-figure run rate as a team of four. Since then, we’ve scaled the team and executed the highest-stakes processes at AIG, SoFi, and Chime. At SoFi, a large US bank, Poetic reached 99%+ quality on fraud investigations in five weeks.

Today, we're announcing A* III, a $450 million early-stage fund. We started @A_StarVC with the simple idea to be a founder's first believer. We are generalists by sector, but specialists in the stage and craft of seed investing. We partner with founders before there is consensus, before there is traction, and often before there is even a product. We are not organized around a market thesis. We back exceptional builders and follow them into the most important categories. That matters because seed investing has changed. It is more crowded, more visible, and increasingly transactional. Too often, firms use seed to secure an option and then wait for proof before investing real time and attention. Seed has become a market of access. We believe it should be a market of conviction. We built A* around a different model. We commit early. We show up before external validation, deploying both time and capital from day zero to help founders find their first customer, make an early hire, or work through the decisions that define the company. We are selective at the start and concentrated over time. We partner with a small number of founders and deepen our commitment as their companies take shape. The best outcomes come from knowing where to go deep and having the discipline to do it. This approach has led us to companies like Ramp, Decagon, Whop, Cape, Simile, Paraform, Watney Robotics, and Mercor. We're grateful to the founders who have chosen to build with us and to the limited partners who have backed us. With this fund, A* manages over $1 billion in assets less than five years after launch. Our job remains what it was on day one: back exceptional founders early and be the partner they need when it matters most.

Telepatia has raised $42 million, including a $33 million Series A led by a16z. My father’s nickname was Telepatia. He was a doctor who passed away at 58 from a preventable cause. A few days after his death, ChatGPT launched. My first thought was that an AI Doctor would have saved his life as a patient, and that he would have loved using one as a doctor. So we built it: an AI Doctor for doctors, by doctors. Telepatia's AI Doctor is live in more than 25 public and private health institutions, home to more than 100,000 doctors and nurses throughout Latin America 🇧🇷🇨🇴🇲🇽🇨🇱🇦🇷 We're building an AI Doctor and our goal is to bring Latin America its first Nobel Prize in Medicine since 1984.
