Harman Chawla

I'm Harman, the CEO of Adstronaut AI. I started my career as a data scientist, then shifted into product management, and now I run Adstronaut — handling product, marketing, and growth day-to-day.

I'm a builder at heart. I write frontend, ship features, and generally believe the fastest way to learn what customers want is to put a working version in front of them. Most of what I write here is from the trenches: real workflows we've shipped, real numbers we've seen, real mistakes we've made.

Before Adstronaut I was at Microsoft and Unbabel (Y Combinator alum). Texas A&M Aggie, class of '17 — Whoop! Currently spending most of my time on growth — which means writing more of these posts.

30-50% of first garment samples require revisions due to miscommunication between designers and factories.

Tech Pack vs Spec Sheet — What's the Difference and Which Do You Need?

A spec sheet is a 1–3 page document listing garment measurements, tolerances, and grade rules. A tech pack is a 10–15 page manufacturing blueprint containing the spec sheet plus flat sketches, bill of materials, construction details, colorways, artwork placement, and packaging instructions. Most factories require a full tech pack to quote and produce — sending a spec sheet alone results in 3–5× more sample revisions.
