Who we’ve worked with

Founder

Jen Mylroie has over 15 years of experience building and scaling marketing teams. As an early employee at Tableau she held various roles over five years as the company grew from 200 to 3,000 employees and went through an IPO. She was the first enterprise and field marketer at InVision and the first integrated marketer at Stripe. Now Jen works with founders and executives to establish and augment teams with interim marketing leadership and strategic project support.

Our Bench

We work with operators who have deep experience at companies like Tableau, Stripe, Databricks, Atlassian, and more. Their expertise ranges from brand to product to demand to marketing operations. They're not advisors—they're builders who work alongside your team to get things done.

  • "Over a year ago she stepped right in and up and you would have never known that she wasn't a full time employee at Vimeo. I want to thank Jen for her commitment and all that she has done to help the team get organized, step in to launch many campaigns and projects, help us document workflows, orchestrate team meetings and in general help us work through whatever needed attention to get over the finish line. We appreciate the care and attention you have given the Vimeo Marketing Team."
