# Harshit Jain — PMM + AI builder

> Principal PMM at ClickUp with 10 years in product marketing. Uses Claude Code, Codex, and Cursor to ship the internal tools marketing teams normally have to ask engineering for — competitive intelligence CLIs, content pipelines, agent routers, memory layers for AI coding tools. Writes the working version of all of it in QBack, a weekly newsletter.

I build the tools PMMs keep asking engineering for. Currently Principal Product Marketing Manager at ClickUp, 10+ years in product marketing across ClickUp, Observe.AI, LeadSquared, QBack, e6data.

This site is queryable by agents three ways: a remote MCP server at https://qback.ai/mcp, in-page WebMCP tools via `document.modelContext`, and the JSON endpoints listed under Agent interfaces below.
