Type system — Geist + Geist Mono

One family, two registers.

Both systems use Geist for text and Geist Mono for the machine voice. The thin look stays; the hierarchy comes from contrast — very light display sizes set against small, heavier subheads, tight tracking on the big sizes and generous leading on the body. Technical suits product, docs and data. Editorial suits long reads like the manifesto.

A — Technical

Precise and dense. Geist Light headings on a tight grid; Geist Mono carries labels, meta and figures.

01 — The line

The Autonomous Software Factory

Nobody has solved full agentic software development yet. Most agentic coding still happens with a human in the driver seat.

The factory primitives

FP

issue graph · local-first

Turns repos, tickets, and half-formed intent into scoped, ordered units of work that agents can pick up and execute.

B — Editorial

Airy and dramatic. Light display sizes against a small, weighty subhead and a tracked kicker; a larger body on a comfortable measure.

The Autonomous Software Factory

Nobody has solved full agentic software development yet. Most agentic coding still happens with a human in the driver seat.

The Autonomous Software Factory is the production system that emerges when agents stop being chat companions and start operating inside compounding loops.

Autonomous does not mean opaque.

It means execution happens without human line-by-line supervision; while intent, evidence, risk, and exceptions remain visible from the control room.

They will be discovered by teams closest to their codebases, their production systems, and their users.
