Growth Marketing Intern

About the Role

The goal of this role is to help the right people discover Sixtyfour, understand what we do, and start a conversation with us. You'll work directly with our marketing lead across content, campaigns, direct mail, and field marketing. This is a role with broad exposure and high visibility, where you'll work closely with marketing, sales, and the founders. You'll own projects that people across the company will see and learn how different marketing channels contribute to pipeline. You'll get context, feedback, and room to develop your judgment. We expect you to take ownership, follow through on the details, and make each round of work better.

What Sixtyfour Does

Sixtyfour provides deep research for a business’s most consequential decisions. Customers come to us when being wrong is expensive. Our marketing makes that work concrete by highlighting the questions customers need answered, how they use Sixtyfour, and what those answers make possible.

Key Responsibilities

• Create engaging content: Write posts, create visuals, and edit short videos. Bring strong ideas and carry them through to finished work.
• Build direct-mail campaigns: Research target accounts, develop thoughtful gifting concepts, source materials, coordinate delivery, and help organize personalized follow-up. Track which approaches start conversations.
• Organize events: Help plan and execute customer and prospect dinners, happy hours, and other field marketing events. Contribute to concept, guest list, invitations, venue coordination, on-site experience, and follow-up.
• Support campaigns: Assist with launches and growth experiments, working with marketing, sales, and founders to turn an idea into a coordinated campaign.
• Identify and articulate value: Turn customer interviews, product demos, and team conversations into clear examples of what Sixtyfour makes possible.
• Test and iterate: Try different hooks, formats, audiences, and channels. Track what leads to replies, registrations, attendance, and meetings, then use those results to shape the next experiment.
• Leverage AI tools: Build faster ways to research, draft, edit, and organize work. Check AI output and apply your judgment to final deliverables.
• Manage projects: Maintain clear next steps, flag blockers early, and close the loop without constant follow-up.

What Success Looks Like

• Your ideas become finished work that we are proud to present to customers.
• Direct-mail campaigns reach the right people and create opportunities for conversations.
• Events attract relevant guests, run smoothly, and have thoughtful follow-through.
• You can clearly explain your testing process, outcomes, and proposed improvements.
• You effectively incorporate feedback into subsequent work.
• You can be trusted to own projects with increasing independence.

Qualifications

• A demonstrated ability to create something you are proud of, such as a video, campaign, newsletter, event, student project, or a grown account. We value your contribution and the quality of the result.
• Strong creative judgment: The ability to discern what makes writing clear, visuals compelling, gifts memorable, or events worthwhile, and articulate your reasoning.
• A strong sense of completion: The ability to take a broad concept, ask pertinent questions, and develop a thoughtful initial draft or a clear plan.
• Curiosity about people: A desire to understand audience interests and motivations.
• Organization and attention to detail: The ability to track timelines, names, addresses, and commitments, recognizing the impact of small details on overall experience.
• Regular use of AI tools: Experience experimenting beyond basic prompts, identifying suboptimal output, and adapting your approach.
• Comfort with data: The ability to work with spreadsheets, identify patterns, and connect activities to outcomes.
• Coachability and resourcefulness: The ability to listen carefully, act on feedback, and attempt to solve problems independently before escalating.
• Previous marketing internship experience is not required. Work done for personal projects, student organizations, communities, or side projects is highly valued.

What You'll Learn

• How an early-stage company translates customer insights into positioning, creative work, distribution, and pipeline.
• Hands-on experience across digital and in-person marketing.
• How to build relationships across the company.
• The impact of your work reaching customers directly.
• You will leave with a portfolio of your contributions and a clearer understanding of your preferred marketing specializations.
