👋 About Me

Hi, I’m Harshit Jain. Currently, I lead the product marketing team at e6data and was previously a founder (QBack: ai agent for PMMs to create sales assets, closed Dec 2024). I’ve spent 9+ years driving GTM as the #1 product marketing hire, launching products, running competitive intel, and creating messaging that actually sells for startups across different categories—Conversational Intelligence (Observe.AI), CRM (LeadSquared), Sales Enablement & Research (QBack.AI), Data Infrastructure (e6data).

That means I’ve marketed to everyone from hardcore tech nerds to folks who’ve never worked beyond spreadsheets.

Outside of product marketing hustle & tech reading, you'll find me watching F1 🏎️, Kurzgesagt on YT, kicking goals (or missing them) in football ⚽, swinging at cricket 🏏, or occasionally pretending to know what I'm doing at the gym 🏋️.

Add me on LinkedIn for opinions on startups, AI, and marketing.
