The Role

About Mass Culture and BRAINS
You’ll work across two distinct but complementary agencies:

  • BRAINS is a creative company built on storytelling, cultural insight, and breakthrough ideas. From brand strategy to fully integrated campaigns, Brains partners with clients to create work that resonates deeply with audiences, sparks conversation, and drives cultural relevance.
  • Mass Culture is a growth marketing partner that believes in the power of brand to drive conversion—not the other way around. Mass Culture builds brand-first creative and combines it with performance marketing expertise across all paid media channels to drive sustainable growth


Head of Business Development

As Head of Business Development for Brains and Mass Culture, you will lead the growth engine across both companies, driving new client acquisition and expanding strategic relationships. This is a senior role for a dynamic leader who can identify opportunities, open doors, and build lasting partnerships with brands who value bold creativity and cultural impact.


Together, Brains and Mass Culture offer brands a unique blend of cultural storytelling and performance-driven growth. Your role will be to shape and execute a unified new business strategy, positioning each company’s individual strengths while uncovering opportunities for collaboration.


Key Responsibilities


New Business Leadership

  • Develop and lead the overall new business strategy across Brains and Mass Culture.
  • Identify, pursue, and secure new client opportunities in key verticals (lifestyle, tech, entertainment, CPG, and beyond).
  • Manage the full pipeline — from prospecting and outreach through to pitch, negotiation, and close.
  • Partner with leadership to shape go-to-market positioning and ensure a cohesive new business narrative for both agencies.


Client Engagement & Relationship Building

  • Build and nurture authentic, long-term client relationships based on trust, creativity, and results.
  • Serve as the first point of contact for potential partners, translating their needs into clear opportunities.
  • Work hand-in-hand with creative, strategy, and production teams to craft compelling proposals and pitch narratives.
  • Represent the agencies with confidence in pitches, presentations, and industry events.


Strategic Growth & Collaboration

  • Collaborate with agency leadership to forecast growth and set measurable new business goals.
  • Track, analyze, and report on pipeline performance using CRM and other tools.
  • Identify opportunities for cross-pollination between Brains and Mass Culture, ensuring clients benefit from the strengths of both.
  • Stay ahead of cultural, industry, and market shifts to inform proactive outreach and positioning.


Agency Marketing & Presence

  • Shape and oversee marketing efforts that amplify the agencies’ profiles in the industry.
  • Partner with leadership and marketing teams to develop thought leadership, case studies, and content that elevate both agencies’ voices.
  • Drive strategy around events, panels, and award submissions to increase visibility and credibility.
  • Ensure Brains and Mass Culture maintain a consistent, compelling presence across owned channels, partnerships, and industry platforms.


Who You Are

  • A proven business development leader with 8–10+ years of experience in creative, advertising, or experiential agencies.
  • A leader, but a doer. Equally comfortable shaping strategy and rolling up your sleeves to execute.
  • A natural hunter and relationship-builder — confident, strategic, and motivated to connect clients with bold creative solutions.
  • Experienced in leading pitches and negotiations, with a track record of closing high-value deals. 
  • A strong storyteller and communicator, able to articulate agency capabilities with clarity and enthusiasm.
  • Entrepreneurial and self-driven, with the ability to work independently while staying deeply collaborative.
  • Highly attuned to culture, creativity, and the evolving brand landscape.

This position offers a competitive salary plus commission.
