Every launch

Engagement is read from X and refreshed daily for the last fortnight; older posts keep the figure and the date it was read. The multiple is views divided by the account's following at the time of reading, shown only where an account has over 500 followers, because below that it flatters the arithmetic rather than the launch.

Launching in this vertical

This page holds every launch in the directory from a company that names a16z, Andreessen Horowitz or the a16z speedrun programme in the launch post or the posting account's bio. It is a16z-backed rather than a16z-led: a post rarely says which role the firm took in a round, so the test is the name.

The speedrun companies sit inside it. The programme's cohorts tend to launch inside the same fortnight, which puts them against each other on the feed. How a16z speedrun companies launch on X reads that cohort effect and the plan that beats it.

Two launches here were run by Doomers. Lightfield announced its $47M Series A led by a16z from a co-founder's account of 6,784 followers to 1.3M views. Codos, a speedrun company, launched the first virtual Chief AI Officer from 1,800 followers to more than a million views on day one.

Every launch here was somebody's one week of attention. We run the version where that week is planned.
