Head of Marketing (Early-Stage B2B | VC-Backed Growth Company)

Location: Boston, MA (On-Site | No Remote)
Stage: Pre-Seed / Early VC
Function: B2B Growth Marketing | GTM | Demand Generation | Brand & Storytelling

The Opportunity

We are partnered with a venture-backed, early-stage B2B company in Boston seeking a hands-on, growth-focused Head of Marketing to join as one of the company’s earliest leadership hires.

This is a builder role, not a maintainer role.

You will work directly with the founding team to shape the company’s go-to-market strategy, build the entire B2B marketing engine from the ground up, and translate the founder’s vision into a compelling, scalable growth story.

The ideal candidate thrives in early-stage environments, embraces ambiguity, and is energized by doing the lift — from strategy to execution — while partnering cross-functionally across product, sales, operations, and leadership.

What You’ll Own

• Build and execute the end-to-end B2B marketing and growth strategy from zero

• Develop and refine the GTM motion, ICP definition, positioning, and messaging

• Translate the founder’s vision into clear, differentiated storytelling across channels

• Personally execute across growth marketing, including demand generation, content, lifecycle, performance marketing, and experimentation

• Lead a test-and-learn culture with strong analytical rigor and bias toward action

• Partner closely with Sales, Product, and Leadership to drive pipeline and revenue impact

• Establish early marketing infrastructure, processes, and KPIs that scale with the business

• Support VC and investor storytelling, including narrative development, metrics, and growth proof points

Who You Are

• A hands-on B2B growth marketer with deep experience building marketing from the ground up

• Proven success in early-stage B2B companies (pre-seed, seed, or early Series A)

• Comfortable wearing multiple hats and operating without layers or large teams

• Deeply aligned with founder-led environments and the commitment they require

• Obsessed with storytelling, positioning, and building a compelling narrative that converts

• Naturally tenacious, resourceful, and energized by experimentation and iteration

• Strong cross-functional collaborator who can influence without hierarchy

• Data-driven, but equally creative in how you approach growth and brand building

Experience & Requirements

• Prior experience as a Head of Marketing / Growth Leader in an early-stage B2B company

• Hands-on ownership of demand generation, growth marketing, messaging, and GTM

• Experience working closely with founders and venture capital partners

• Strong understanding of B2B SaaS or B2B technology growth motions

• Willingness and ability to work on-site in Boston (this role is not remote)

• Energized by building — not inheriting — a marketing function

Why This Role

• True 0→1 marketing leadership opportunity

• Direct partnership with visionary founders

• High visibility with VC stakeholders

• Opportunity to define the brand, growth engine, and GTM strategy from day one

• Meaningful ownership and impact at a formative stage of the company

How to Apply

If you are passionate about early-stage B2B growth, thrive in founder-driven environments, and want to build something meaningful from the ground up, we’d love to connect.
