Compound Engineering: How Every Codes With Agents

Co-authored by Dan Shipper (Every CEO) and Kieran Klaassen, this is the definitive framework piece. Every runs five software products in-house, each primarily built and run by a single person. Nobody writes code manually anymore.

The four-step loop: Plan (agents research and synthesize implementation plans), Work (agents write code and tests), Assess (engineer reviews output and lessons learned), Compound (feed results back into the system to improve future loops). Roughly 80% of effort is in Plan and Assess, only 20% in Work and Compound.

The counterintuitive claim: in compound engineering, each feature makes the next one easier to build, reversing the traditional pattern where growing codebases create exponential complexity. The system’s knowledge of the codebase grows alongside its complexity.

Every released a Claude Code plugin implementing this workflow for public use. The framework is tool-agnostic — some team members also use Factory.

RDCO mapping: The 80/20 split (planning+review vs. execution) is a strong operational principle for any AI-augmented workflow. The four-step loop could be adapted for content production: Research, Draft, Review, Compound (where editorial feedback improves the system for next time). The single-person-per-product staffing model is the RDCO thesis in action.
