Greylock Partners engagement report
@GreylockVC - 297K followers on X
Measured over 7 original posts from a 30-day window, last computed on October 21, 2026.
Engagement
Early reading. We have captured 7 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 23 interactions against 297K followers, an engagement rate of 0.008%. Posts are seen about 4.4K times each, and 0.527% of those impressions turn into an interaction. That is about 1.47% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.93 post a day over the last 30 days, though only 37% of days saw any activity at all. Most posts go out around 15:00 UTC, and Wednesday is the busiest day of the week. Of the 7 posts sampled, 86% carry an image or video, 43% are part of a thread and 14% link out. The account's strongest tracked post pulled 1.2K interactions, about 49x its own typical post. Only 7 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 15:00 UTC, and Wednesday 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 | 86% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 14% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 86% 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.
- 14% 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 470 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
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 Altara: the scientific intelligence platform for the physical world. Today @evatuecke and I are excited to announce our $7M seed led by @GreylockVC, joined by @Neo, @BoxGroup, @Liquid2V, and angel investors including @JeffDean and leadership from OpenAI & AMD. Weโre already working with early customers in semiconductors, batteries, and advanced materials. More below.

We're launching @niteshiftdev โ the full-stack cloud for coding agents Verification is the new bottleneck. Software teams can now define their dev environment and verification tools once. Then run any frontier agent in the cloud: Claude Code, Codex, or OpenCode https://t.co/051yfOGPzm

how can startups compete with billion $ monster companies? consider cloud coding agents: @cognition: 3 IOI gold medalists, 1B+ funding, 20B+ valuation, 80 hour work weeks, 300+ employees, billboards all over sf, colossus @niteshiftdev: two random datadog engineers (@smehmood, conor branagan), 7m seed round, barely on twitter, pretty sure you haven't heard of them we've used both for weeks (and longer for devin) and niteshift is clearly the better product maybe in a year devin will actually be good but right now it's less flexible, tries to do too much, and the actual code that comes out on the other end is no better the monster company can do a lot of things but it's very very hard for it to do less even that's the right call

Congrats, @CorinneMRiley, on making the Forbes Midas Brink list, a recognition for the next generation of investors poised to shape venture. We want the world to know what we see every day: Corinne brings relentless support to every founder, rolling up her sleeves on whatever the company needs, big or small. She backed @baseten, @usebraintrust, @resolveai, @cogent_security, @FableSecurity, and @altaratech before the rest of the world caught on. She has also built platforms that serve founders well beyond her own portfolio, from Greylock Edge to the Scouts program to Greylock Change Agents. Her energy is unmatched. None of this happens without the founders who trusted us as their first believers. They are the reason this recognition exists, and we are deeply grateful. So proud of you, Corinne.

Introducing ๐๐ ๐๐ฟ๐ฎ๐ฐ๐๐๐ฒ๐ป๐ฐ๐ต: the most comprehensive benchmark for information extraction from complex enterprise documents. Our applied research team tested: 14 systems โ frontier VLMs, coding agents, extraction APIs โ on 370 enterprise docs, 4,869 pages, 67 doc types. Zero LLM judges, fully deterministic. Biggest finding: past 50 pages, commercial VLMs collapse below 35% recall. Precision stays high, but they silently drop most of the table rows. What is your extraction agent missing? Run ExtractBench to see today. Blog: โจhttps://t.co/5UE8frCm9Y GitHub:ย https://t.co/27vJ36bL54 HuggingFace:ย https://t.co/oeGlwPjcQh

Greylock is excited to lead @antiochrobotics's $32M Series A, with participation from @A_StarVC, @Category_VC, @BoxGroup, @IcehouseVenture. AI has shrunk software development cycles from weeks to days, but that speed has not yet reached the physical world. Physical validation processes have been a barrier to physical AI development and adoption speeds, as slow, costly testing bottlenecks progress. Introducing @antiochrobotics, the simulation platform for physical AI. Antioch enables robotics and autonomy teams to develop, test and validate AI systems in high-fidelity simulation, scaling from a single experiment to thousands of parallel evaluations before real-world deployment. By calibrating high-fidelity simulations to each customer's hardware and running them at cloud scale, the platform enables companies to accelerate development, increase test coverage and bring new capabilities to production faster. With experienced, second-time founders and partnerships with leading physical AI teams already in place, we believe Antioch is building the core platform for the future of physical AI. Weโre excited to partner with @HarryMellsop, @AlexLangshur @michaeljcalvey and @CollinSchlager for what comes next. Read more on our investment blog (link in comments).

- Greylock Partners (@GreylockVC) has an engagement rate of 0.008%, based on the median interactions across 7 original posts from the last 30 days against 297,361 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.008%, Greylock Partners sits above the 10th percentile of the 205,475 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
