Hi! I’m Libby, a NYC-based growth & marketing consultant

Say goodbye to chaos

I work with Seed–Series B consumer services and technology startups to unlock step changes in CAC.

Through focused growth sprints, I help teams nail positioning, validate growth levers, and scale with confidence.

Puzzle-solver by nature, operator by training, and marketer by happy accident. Find my playbooks and lessons on Substack.

Who I am

I began my career at BCG, learned to run a P&L as a Caviar GM (acquired by DoorDash), and then pivoted into marketing. Since then, I’ve built marketing from the ground up for 20+ startups in both in-house and fractional leadership roles.

A coworker once described me as “a marketer with an engineer’s brain.” Read more about me.

What I help with

I help startups create marketing-led growth engines that drive results.
You may need me if one or more of these problems sound familiar to you:

🚦 The Getting Started Problem

You have some early customers and are ready to hit the gas on growth. But you’re overwhelmed by options - what channels to pick, what messages to focus on, and who to hire to execute.

🚰 The Kitchen Sink Problem

Your team throws everything but the kitchen sink at growth and isn’t sure which actions drive outcomes. You are looking for a clear playbook to help you drive repeatable growth.

📉 The Diminishing Returns Problem

The channel(s) that have worked in the past are degrading and your CAC is increasing. You’re looking for a way to diversify your growth playbook & drive compounding results.

How we work together

I work with passionate, collaborative teams to accelerate growth. Once we start working together, it will feel like I’m a part of your team because I am.

Fractional Leader

For startups with 4+ marketers

I embed into your organization and provide senior-level marketing leadership, working alongside your team.

Player/Coach

For startups with 0-3 marketers

I support both strategy & execution, taking on specific projects to run on my own and directing the team's day-to-day work.

Coach

For leaders on a small budget

I guide you through a series of structured workshops to establish a marketing strategy, develop an experimentation roadmap & help you hire the right resources to execute.

My philosophy

Great marketing is thoughtful, intentional & takes time to bring to life, which can sometimes feel at odds with a startup's fast-paced, constantly changing environment. But startups that slow down first to go fast later are the ones that win.

My training is in big-picture strategy & analytics, but I’ve lived in amorphous startups for the last eight years, where trial & error, brute force effort, & perseverance are the game's name. I bring the best of these worlds together to avoid mistaking motion for progress.

My approach is to help you develop conviction in your marketing foundation by grounding the work in a deep understanding of what your customers care about, think about, and dream about and why they care about what you’re building. This foundation serves as a springboard for new channels & iterative experimentation that unlocks predictable growth.

Ready? Let’s begin

I give clients my dedicated focus and make their priorities my priorities, so I’m only able to take on a few projects each year. If you think there’s something great to be made together, feel free to drop me a line.
