What Is an AI Product Manager: The New PM Stack for Agentic Workflows

An AI Product Manager (AIPM) is a product manager who builds, prototypes, and ships software directly with AI agents like Claude Code, using semantic search, repos, and evals as their daily toolkit. The role has shifted from writing specs and managing handoffs to chatting with codebases, vibe-coding prototypes, and designing evaluation loops for stochastic outputs. This page explains the AIPM workflow, the tools that matter, and how PMs at companies like Lemlist restructured their job in under three months.

Audience: Product managers, heads of product, and founders re-tooling their PM function around AI-native workflows.

Models vs Harnesses: Why the System Around the LLM Matters More Than the Model

A harness is the system around a large language model—planning, context, evaluations, and tooling—that turns raw intelligence into useful work. Practitioners report that models hav

Semantic Search, Repos, and Evals: The Three Primitives of AI Product Work

Semantic search, repos, and evals are the three primitives of modern AI product work. Semantic search retrieves by similarity instead of exact IDs, repos store reusable context lik
