Founding Growth Marketer

Spine AI is an unlimited canvas where users think and create with the power of 300+ AI models. We're building a new paradigm for thought and creation – allowing product managers, designers, marketers, and students to go from idea to final artifact (reports, slide decks, prototypes) faster than ever before. We're a small, ambitious YC S23 team, and we need a passionate marketer to build our growth engine from zero.

As our first marketing hire, you are the founding architect of Spine AI's brand and growth strategy. This is a true 0-to-1 opportunity where you won't just run campaigns – you'll talk to our first users, craft our core message, experiment across every channel, and build the entire marketing function from scratch. You're a storyteller, community builder, and growth driver rolled into one.

Translate Power into Value

• Take abstract concepts like "AI-amplified thinking" and turn them into concrete, compelling benefits
• Show a product manager how to turn user feedback into a full product brief in minutes, not hours
• Create "recipes for success" by developing and marketing our templates (Competitive Analysis, Product Launch Plan) to demonstrate immediate value

Show, Don't Tell

• Create engaging content that captures the magic of the Spine AI canvas—short videos, GIFs, tutorials demonstrating branching, context passing, and parallel model execution
• Build scrappy, high-impact assets: social posts, newsletters, blog content, landing pages, case studies
• Publish 3-5 pieces per week across LinkedIn, Twitter, email, and our blog

Own the Channels & Drive Pipeline

• Build and manage our presence across social media, blogs, and community forums
• Launch 2-3 simple lead magnets and capture emails
• Run targeted outbound: DMs/emails per day to our ICP, booking 5-10 qualified meetings per week
• Execute scrappy paid experiments with small budgets ($500-$2,000 tests)

Launch & Iterate

• Plan and execute go-to-market strategies for new features
• Run growth experiments across acquisition, activation, and retention
• Track metrics (signups, CAC, conversion rates) and report weekly on what's moving the needle

Be the Voice of the Customer

• Conduct user research to deeply understand our ICP (product managers, designers, PMMs, students)
• Partner with founders on product-market fit insights from customer conversations
• Refine messaging and positioning based on user feedback

A Scrappy Executor

• You have a "roll-up-your-sleeves" mentality and can pass the "button-clicker test"
• Comfortable with ambiguity and ruthless prioritization
• Biased to action—you ship imperfect v1s and iterate fast
• Self-directed with high ownership—you don't need hand-holding

An Exceptional Communicator

• Strong writer and editor who can craft clear, concise, compelling copy
• Can turn raw inputs into crisp posts, emails, and scripts that resonate with sophisticated users
• Visually inclined with a good "eye for design"—handy with Spine, CapCut, and other tools to create appealing materials quickly

Deeply Curious & Data-Driven

• Eager to learn and experiment across various marketing channels
• Data-curious but also creative—you can analyze funnels and write compelling copy
• Quick learner who can demo the product credibly

Experience & Background

• 0-3 years experience (recent grad or early career switcher) with a builder mentality
• Bonus: Experience with developer tools, SaaS, or AI products
• Nice-to-haves: Ran a personal newsletter, community, or social presence; startup internship experience; basic SEO, Webflow, HubSpot/Mailchimp/Apollo knowledge
