Portrait of Eric Mandell

My experience

I've built and scaled some of the most recognizable startups in consumer tech, health, and education.

As VP of Marketing at MIRROR, I grew the company from launch to $150M in revenue and helped lead it through a $500M acquisition by Lululemon.

Prior to that, I served as Fractional Head of Growth at Codecademy and Maven, helping both companies bring new products to market, grow revenue, and scale through major funding rounds.

Today, I work as a strategic growth advisor, partnering with early-stage companies to clarify go-to-market strategy, level up internal talent, and instill data-driven decision-making processes.

What others say

Eric was instrumental to MIRROR's success from pre-launch through our acquisition. Pre-launch, he built our data and analytics foundation, and developed the strategy behind our incredibly successful launch. As we grew, he figured out how to massively and efficiently scale the business, and built the team to support it. He brings rare range, equally sharp on strategy, execution, and people. He's the kind of partner every founder wants in the room!

Eric has been an invaluable partner from Maven's earliest days. He helped us launch our paid marketing efforts and develop a data tracking strategy that allowed us to scale rapidly in the years that followed. He built an SEO strategy that drove hundreds of thousands of visitors to our site and massively grew our brand awareness. He was also an amazing thought partner in building our growth team, helping us identify the strengths of the current team and guiding us on where to hire. I highly recommend hiring Eric!

Eric has been integral to Triplemoon from the moment he joined the team. His ability to balance a broad, strategic ‘macro’ perspective with a detailed, hands-on approach is a rare and powerful combination that has allowed us to iterate thoughtfully and experiment quickly. His contributions have been transformative, and Triplemoon would not be where it is today without his expertise, network, and support.

Eric came in to help level up our growth marketing program, and he was a sharp thought partner throughout the engagement. For example, he identified registry as a meaningful, under-invested driver of our business, led the analysis to model its long-term impact, and helped build the business case for investing in it as a channel. He's the kind of strategic partner I'd want alongside me for any growth challenge ahead!

As a new Head of Marketing joining Codecademy, Eric was exactly the partner I needed to hit the ground running. He added immense value both strategically and analytically. He shaped our approach to paid marketing, email acquisition, measurement, and the reporting tools and processes we built around it. Any marketing team would be lucky to have him in their corner.

How I think

I'm deeply data-driven and naturally analytical.

I use data to help teams get clear on what actually matters. When I look at a business, I try to understand the key levers driving the most important metrics, and use the learnings to figure out what to do next.

I'm at my best helping teams pressure-test their assumptions, clarify trade-offs, and focus on the highest-leverage opportunities.

How I work

I move fluidly between strategy and execution.

I don't believe in tightly scoped, static projects. Startups move too quickly. Instead, I embed with teams in a flexible way, adapting my priorities as we learn.

That might mean zooming out to sharpen go-to-market strategy, or getting deep into the weeds on a specific channel, experiment, or decision. My goal is to be a true extension of the team as priorities evolve.

I work with a small number of teams each year.
