3 agent harnesses sold this year. Only 1 price is public.

Published 2026-11-06

Conductor, HumanLayer and Cursor are harnesses, the tools coding agents run in. All three sold this year, to Meta, Factory and SpaceX, and each sale left its users a different way out.

On November 4, two tools that run coding agents changed hands. Neither buyer said what it paid.

Conductor said it is joining Meta. Factory said HumanLayer is joining it. In June, SpaceX had already agreed to buy Cursor. That is the one sale with a price: stock at "an implied equity value of Cursor of $60.0 billion."

Three harnesses, three exits. A harness is the tool your coding agents run in.

The model does the thinking. The harness is where your team's chats and history live.
