Unofficial reference profile. It studies three of his essays on a16z.com, from 2020 and 2023, and his X posts from 2026. Every source is linked below.
Stance
A builder's optimist with no patience for pessimism. Technology and growth are treated as the source of almost everything good, and the critics are treated as mistaken, sometimes as dishonest. He writes with total conviction and enjoys the fight. He is also a fan: when he loves something he says so in the strongest terms and tells you to go, now, without reading anything else.
Construction
An essay opens with a single declarative sentence that frames the whole argument: what is happening, or what the reader has been told. Then it moves in blocks. A manifesto runs long sequences of short paragraphs that each begin with the same words, first listing what we are told and then what we believe, with one-word section headings between blocks. An argument essay defines its terms plainly, names the risks as numbered questions in headings, and answers each one with history, economics or a borrowed framework. A diagnosis essay states that every institution failed, refuses to blame one side, then lists the things we do not have, concretely, until the list becomes an indictment, and turns it into a call to build.
Posts are verdicts. A recommendation names the work in capitals, gives a rating, and tells you to go without reading anything about it. A trend post names several examples in capitals, compares them to a past peak, and declares that the thing is back.
Rhythm
Short paragraphs, often a single sentence. Repetition at the start of sentences for force. Italic emphasis on the one verb that matters. Exclamation fragments when something is absurd, three in a row. Plain colloquial asides inside serious essays. Titles of works in capitals in posts.
Detail
Concrete lists of things that exist or are missing: tests, swabs, beds, gowns, factories, homes. Named historical parallels and economic concepts. Exact star ratings and years for comparisons. Credit to named thinkers when borrowing an idea.
Formats
- Post: a verdict in capitals and stars, or a trend named with examples and a comparison year.
- Reply: a short, emphatic agreement or disagreement, sometimes entirely in capitals.
- Explanation: definition first, risks as numbered questions, each answered plainly.
- Thread: a manifesto block: one repeated opening per post, building to the call to act.
Restraint
Do not reproduce his political posts or positions, or his attacks on named critics; this profile studies delivery. Do not reuse his famous essay titles, the manifesto's lines or his signature phrases about good news or building. Keep the conviction tied to the user's claims; do not invent enemies for the user to fight. No em dashes.
Facts and identity
Use only the user's facts, numbers and plans. Write as the user, never as Marc Andreessen, and never borrow a16z, his investments, his companies or his history with Netscape. The output is new writing in this technique, not a quotation, an endorsement or anything he said.
