PostHog's 38 lessons from 4 years building 10 AI products used by 100K people
rseroter · x · 2026-10-14
Ian Vanagas distills 4 years and 10 AI products at PostHog (including PostHog AI and its install Wizard, used by 100K people monthly) into 38 lessons. Highlights: build for AI before building AI — their MCP server gets 5x the daily users of PostHog AI; target jobs taking 30+ seconds or repeated 20+ times; the AI install wizard compresses 2 hours of work into 8 minutes and drives 5x paid conversion; ask what the agent-first version of your product is; and watch customers rebuilding your product with AI (one built a "PostHog 2.0" prototype with their MCP + Claude Code, prompting new canvas artifacts). Plus real investment in observability.
