Machine Shops Size
a16z's bar chart drew 256.5K views on X: 3.5x its typical post and #17 of 43 a16z charts we track by views. Read Oct 10, 2026.
America has 16,876 machine shops.
Why it spread
This post spread because a large account with a top quarter source reach paired a striking count of 16,876 machine shops with a simple bar chart showing that most are small businesses, and it earned 1,614 likes, 184 reposts, 54 quotes, and 1,256 saves against 256,468 views, which is 4.8x the account's typical likes.
What worked
- The headline number of 16,876 machine shops gives the chart a concrete, surprising scale that is easy to repeat.
- The framing that 83% employ fewer than 20 people and just nine employ more than 500 turns a dry distribution into a clear story about fragility and concentration.
- The post connects the chart to a timely defense production narrative, and the above average quote rate plus 54 quotes show people used it as a conversation starter rather than just a like.
What to borrow
We can take our own category count, show the share that sits in the smallest group and the tiny number at the top, and tie it to a current shift our audience already cares about.
Careful
Do not copy the defense framing if our data does not support it, and do not read the 4.8x lift as proof that the chart design alone caused the spread, since the large source reach and the many quotes also drove it.
