Flox's engineering team is 30 people. In six months, they 50x'd their output without adding a single engineer. Ron Efroni, CEO and co-founder of Flox, explains how.

Michael Grinich sat down with Ron at the AI Engineer World's Fair to talk about how Flox uses AI agents on top of a Nix-based architecture: giving each task a "conviction" threshold agents have to clear before shipping, compartmentalizing company knowledge with an internal system they call Forge, and why knowing every dependency by file path means you can remediate a CVE without ever running a scan.

In this conversation:

• Why Nix is the "cryptographic layer" for software that has to run the same everywhere
• Turning legacy systems into atomic, roll-back-able units you can modernize with conviction
• Running agents and 100+ sandbox platforms inside hermetic, portable environments
• The conviction threshold: 50% for the web UI, 80% for the package layer, humans on the rest
• How a 30-person team avoided hiring 10–15 more engineers
