Job description

About Sixtyfour

Sixtyfour helps teams understand the people, companies, and entities they interact with. With a primary focus on Compliance (AML/KYB), Trust & Safety, Cybersecurity, and Investigations. Our platform combines agents, LLMs, and large-scale data infrastructure to surface data other platforms can't.

The Role

We're looking for a Growth Intern to work alongside our Growth Lead and founders on everything that gets Sixtyfour in front of people. This is not a shadowing role. You'll publish under our accounts, cut demos that go out, and run experiments with real budget and real numbers attached.

The bar is that you ship. If you'd rather be given a list of tasks than find your own, this isn't the right fit.

What You'll Do

• Write and ship posts from our LinkedIn and X accounts, with your drafts going live rather than sitting in a doc
• Support launch weeks: cut demo clips, put together case studies, help run benchmarks against the tools buyers already use
• Run your own experiments. Pick a channel or an idea, ship it, report what happened, keep or kill it
• Help build the raw material for growth stunts: live investigation runs, free tool drops, bounties, claims we can prove
• Do the research that makes content credible. Pull the data, check the competitor claims, find the examples
• Track what's working. Own reporting on traffic, signups, and where they came from

What We're Looking For

• Currently enrolled or recently graduated, any major
• Something you made and put in public. A newsletter, an account, a project, a video series, a site, anything with real usage
• You write clearly and quickly
• Curious enough about the product to run it yourself and form opinions without being briefed
• Comfortable with spreadsheets and analytics tools, or fast enough to get comfortable
• Self-directed. You'll get context and goals, not step-by-step instructions
• Available full-time for the internship period and based in or able to relocate to the San Francisco Bay Area

Nice to Have

• Video editing, design, or basic frontend skills
• Comfortable building small tools with AI coding assistants
• You already follow the AI and security space and have opinions about who does marketing well
• Prior startup or internship experience at an early-stage company

Benefits

• Paid internship
• Lunch on us in the office
• Monthly AI tools/productivity reimbursement
• Flexible working hours
• Direct work with the founders, and a real shot at a full-time offer
