General Manager of Cora · Every

Career

Klaassen’s personal writing spans software, team leadership, music and craft. His 2026 conference biography identifies Cora, Every’s email product, and his work applying agent-assisted development to product teams. His current public account places him on Every’s frontier team.[1][2][4]

Ideas

His compound-engineering talk moves from choosing and brainstorming a problem to planning, implementation, review, polish and preserving what was learned. Corrections and the reasons behind decisions become retrievable guidance rather than answers repeatedly rediscovered in chat. Human attention concentrates on framing the goal and reviewing the result while agents carry the middle stages. The intended compounding comes from reusable judgment, including taste and constraints, rather than merely accumulating more generated code.[3]

    A product-development workflow that preserves decisions and corrections as reusable context.

    Start with the workflow and decision-documentation chapters. Familiarity with pull requests helps; the central practice is to preserve why a decision was made so later work can retrieve it.

    Speaker[3]
  • Rebuilding an email client alone since January without reading most of the code, he traces the bottleneck as it moved from code quality to plans to knowing what to build at all. What was left was him repeating himself, which is what a memory system exists to fix.
