AI Startup Marketing Internship (Unpaid, With Training)

AI Startup Marketing Internship (Unpaid, With Training)

Want hands-on experience in outreach, SEO, GEO, social media, influencer marketing, PR, and growth strategy at a real, funded AI startup?

You'll be joining the marketing team at
Unstoppable
, an AI company building an agent-agnostic orchestration workspace, letting developers run multiple AI coding agents (Claude Code, Codex, and others) in parallel inside one environment, with a broader vision of helping teams manage and optimize all their AI usage in one place.

Unstoppable has brought in
GrowthExpertz
, a startup marketing agency led by 20+ year veteran Andrew Lee Miller, to build out their marketing function from the ground up. You'll work directly with Andrew and the Unstoppable team, getting real ownership over projects and direct mentorship, not hypothetical assignments.

Rather than working on hypothetical projects, you'll gain hands-on experience helping grow a real startup's marketing engine from day one.

We're looking for people who want to work hard, take ownership, and get things done. Upon successful completion of the internship there most likely will be a full-time job offer after, if you work hard.

What You'll Work On

You'll get real exposure across multiple channels, all tied to actual campaigns that drive developer signups, product adoption, and brand awareness. Depending on your skills and interests, you may work on:

Outreach & Lead Generation

• Researching and building targeted lists of developers to reach via email and LinkedIn
• Drafting and testing outreach messaging and sequences
• Tracking response rates and helping optimize what's already running

Content & SEO/GEO

• Writing blog posts and technical articles targeting high-intent searches: AI coding agents, dev workflow tools, and competitor comparisons
• Researching keywords for both traditional search and AI search (ChatGPT, Perplexity, Google AI Overviews)
• Building content structured to get Unstoppable cited when developers ask AI which agentic coding tool to use

Social Media

• Creating and scheduling content for Unstoppable's official account and founder/exec accounts
• Drafting product education posts, industry commentary, founder story content, and user proof, etc...
• Light design work using AI tools and Canva

Influencer & Partnership Outreach

• Researching and building lists of developer and engineering creators with real, engaged audiences
• Drafting outreach messages and tracking responses

PR

• Building targeted journalist and podcast lists across developer tools, AI, and startup/tech beats
• Drafting PR pitches and HARO/Qwoted responses
• Supporting outreach to relevant podcasts

Developer Community & Platform Presence

• Researching where developers are actually talking about agentic coding tools (Reddit, Hacker News, GitHub, X, Discord)
• Helping monitor and engage in relevant communities and threads
• Supporting keyword and positioning research for competitor-comparison landing pages

Analytics & Reporting

• Tracking performance across channels using GA4, Google Search Console, and social platform analytics
• Contributing to weekly KPI reporting

This internship is designed for you to explore different channels, find where you add the most value, then go deep, with real coaching every step of the way.
