Growth Marketing Intern, Sixtyfour

The goal of this role 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. That could mean creating a video, developing a gift campaign for prospective customers, or helping bring together a room of trust and safety leaders. This is a role with broad exposure and high visibility. You’ll work closely with marketing, sales, and the founders, own projects 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’ll expect you to take ownership, follow through on the details, and make each round of work better. What Sixtyfour does Sixtyfour is deep research for a business’s most consequential decisions. Is every one of the 150 engineers a company lists actually on its team? Is that remote vendor who they say they are? Customers come to us when being wrong is expensive. Our marketing makes that work concrete: the questions customers need answered, how they use Sixtyfour, and what those answers make possible. What you’ll do

• Make things worth paying attention to. 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.
• Bring people together. Help plan and execute customer and prospect dinners, happy hours, and other field marketing events. Contribute to the concept, guest list, invitations, venue coordination, on-site experience, and follow-up.
• Help campaigns happen. Support launches and growth experiments, working with marketing, sales, and the founders to turn an idea into a coordinated campaign.
• Find the story. Turn customer interviews, product demos, and team conversations into clear examples of what Sixtyfour makes possible.
• Test and improve. 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.
• Use AI well. Build faster ways to research, draft, edit, and organize work. Check the output and bring your own judgment to what ships.
• Keep your projects moving. Maintain clear next steps, flag blockers early, and close the loop without needing someone to chase every detail.

What success looks like

• Your ideas become finished work that we’re proud to put in front of customers.
• Direct-mail campaigns reach the right people and create openings for conversations.
• Events attract relevant guests, run smoothly, and have thoughtful follow-through.
• You can explain what you tested, what happened, and what you’d change.
• You take feedback well and apply it to the next piece of work.
• We can trust you to own a project with increasing independence.

You might be great for this role if

• You’ve made something you’re proud of. A video, campaign, newsletter, event, student project, or account you’ve helped grow. We care about what you contributed and the quality of the result.
• You have strong creative judgment. You notice what makes writing clear, a visual compelling, a gift memorable, or an event worth attending—and can explain your choices.
• You finish things. You can take a loose brief, ask useful questions, and turn it into a thoughtful first draft or clear plan.
• You’re curious about people. You want to understand what an audience cares about and why someone would respond.
• You’re organized and attentive. You keep track of timelines, names, addresses, and commitments. You understand that small details shape someone’s experience.
• You use AI tools regularly. You experiment beyond the first prompt, recognize weak output, and know when to change your approach.
• You’re comfortable with numbers. You can work in a spreadsheet, spot a pattern, and connect activity to an outcome.
• You’re coachable and resourceful. You listen carefully, act on feedback, and try to solve problems before escalating them.

You don’t need a previous marketing internship. Work you’ve done for yourself, a student organization, a community, or a side project counts. What you’ll learn How an early-stage company turns customer insight into positioning, creative work, distribution, and pipeline. You’ll get hands-on experience across digital and in-person marketing, build relationships across the company, and see your work reach customers directly. You’ll leave with a portfolio of work you helped ship and a clearer understanding of which parts of marketing you want to pursue. How to apply Share two or three examples of things you’ve made, organized, or helped grow. For each, tell us what you owned, why you made the choices you did, and what happened. Include your availability, when you could start, and whether you can work in person in San Francisco.
