Draft: LinkedIn short_post (~120 words) — smt-b7th-engineer

Copy draft — smt-b7th-engineer

LinkedIn short_post (canonical idea 1, ~120 words).

Adding a 7th engineer to your 6-person team will probably make you ship slower.

Brooks wrote it in The Mythical Man-Month in 1975: adding people to a late project makes it later. Communication paths grow as n(n-1)/2. Six people: 15 links. Seven: 21. Every new connection is a Slack thread, a meeting, or a misaligned assumption.

And in 2026 the bottleneck has finally shifted. AI coding assistants have compressed per-engineer output. The thing you can't automate away is coordination.

Wu, Wang & Evans (2019) analyzed 65M+ papers, patents, and software products across 50 years. Small teams cite older ideas. They produce the more disruptive work — at scale.

Large teams develop. Small teams disrupt. Stay small. Ship more.

  "notesForEditor": "Founder-voice, direct, no hype. Hook lands immediately, then the math, then the AI-era reframe, then the Wu et al. data, then the operating stance. Two of three brief sources cited inline (Brooks/Forbes framing + Wu et al. Nature). MIT CISR surfaced as the third claim in the JSON claims array to satisfy the 2-of-3 source requirement while keeping the post body tight at 117 words. No banned words (game-changing, unlock, delve, leverage as verb, revolutionize, seamless, elevate). CTA is implicit \u2014 'Stay small. Ship more.' is a stance, not a generic 'let me know your thoughts' ask."
