## Description
What does it really take to build one of the most important (and least understood) roles in modern startups?
*Check out the GTM Engineering Playbook for your company:* 🔗

I spent the day at the tech startup Clay with Everett Berry, the Head of Go-to-Market Engineering, to figure out what exactly is a go to market engineer? And how did it help scale this startup to a $5B valuation?

Clay is a B2B SaaS startup that helps teams turn data into a highly personalized go to market strategy. 

From LinkedIn posts during the commute to back-to-back meetings, I followed Everett through his full work day—getting a firsthand look at how GTM engineering sits at the intersection of engineering, sales, and marketing, and why it has become one of the fastest growing roles for startups. 

Watch until the end and you’ll understand why this role is already shaping how the best companies scale—and why Clay has not one but two go to market teams.

Final pickle review: Not my favorite.
