Head of Marketing

Greenway Collins is working with a fast-growing, venture-backed healthcare company building a new model of mental health support for teenagers.

The company has raised a substantial Series A from leading investors, grew more than 10x last year, and is now scaling across health plans, managed care organisations and state agency partners. They are hiring their first senior marketing leader to build the marketing function from the ground up.

This is a hands‑on Head of Marketing role for someone who can prove they have built both brand visibility and commercial demand in a difficult B2B market.

The first 6-12 months will be highly execution-led. You will own brand, positioning, content, PR, social, conferences, sales enablement, paid campaigns, funnel optimisation and pipeline contribution. You will be expected to write, build, test, measure and iterate yourself before growing the team underneath you.

You should be able to show clear evidence of:

• Taking a company, product, category or channel from low awareness to meaningful market recognition
• Creating campaigns, content, PR, social or thought leadership that produced measurable attention, not just activity
• Generating or influencing sales pipeline through demand generation, ABM, paid channels, lifecycle, events, or sales enablement
• Using attribution, funnel data, CAC, conversion rates or campaign metrics to improve marketing performance
• Supporting complex B2B, enterprise, healthcare, payer, government, benefits, EAP, behavioural health or similarly long-cycle buyers
• Writing or directly shaping market-facing content yourself
• Operating as an IC without relying on a large team, agency stack or mature marketing infrastructure

The strongest candidates will have been a Director of Marketing, Head of Marketing, Head of Growth, Product Marketing Lead or Demand Generation Lead at a high-growth B2B startup. Healthcare experience is very useful, especially around payers, Medicaid, MCOs, behavioural health, EAPs or public sector buyers, but it is not essential.

What is essential is evidence that you can make a complex B2B category more visible, more credible and more commercially effective.

This is probably not right if your experience is purely consumer marketing, pure brand without pipeline impact, pure performance without narrative or content range, agency-only, or mostly managing teams rather than doing the work directly.

This is a rare chance to build the marketing function at a fast-scaling company with serious backing, a real mission and a very open field for someone who can prove impact rather than just talk about brand.
