Brand and Growth Marketer

About Slingshot AI

Slingshot AI is the team behind Ash, the first AI built specifically for mental health. The company’s goal is to make support easier to access and help people make meaningful changes in their lives.

The organization is focused on building an exceptional team by giving people the autonomy, flexibility, and support they need to do their best work. It values ambition, rapid iteration, and genuine care. The team includes specialists across machine learning, product, engineering, conversational design, clinical work, growth, and operations, with offices in New York City and London. The company is well funded as a Series A business, having raised $93M from Andreessen Horowitz, Radical Ventures, Forerunner Ventures, and other top technology investors.

Role Overview

This position sits at the intersection of brand and growth for Ash as it moves from early traction to defining its long-term growth model. The right person will explore and validate which channels can create demand for the product, including word of mouth, paid media, social, experiential marketing, partnerships, and clinical referrals.

The role is highly hands-on and spans marketing broadly. You will work across brand, growth, and product to spot opportunities, test them quickly, assess results with data, and invest further in what performs. One month could involve launching a brand campaign; another may focus on building a referral loop, improving onboarding messaging, or finding a new growth path through clinicians.

This is a builder-heavy role with little reliance on agencies and a strong emphasis on doing the work directly. You will create copy, build campaigns, set up experiments, analyze performance, and collaborate closely with the marketing team, the Head of Marketing, and the founders. The environment rewards creativity, speed, learning, and original thinking. Candidates should be comfortable turning ideas into action immediately and may use tools such as Claude Code to help build.

What You Will Do

• Identify and test new growth channels by forming hypotheses, running quick experiments across paid, organic, social, experiential, referral, and partnership channels, and using analytics to determine where to invest further.
• Plan and execute integrated brand campaigns on a roughly two-month cadence, working with the social lead and creative partners to define the message, placement, and connection to the product experience.
• Manage the full funnel by understanding how users discover, try, activate, and retain Ash, then improving messaging, onboarding, lifecycle journeys, and monetization where needed.
• Convert user research, direct customer conversations, and behavioral data into positioning decisions, product recommendations, and the next set of experiments.
• Create measurement and feedback systems that show what is working within weeks so the broader team can learn and adapt faster.
• Develop unconventional sources of demand, including potential advocacy from doctors and therapists or distribution through communities.

What We Are Looking For

• 3 to 5 years of experience in growth marketing, brand marketing, integrated marketing, or lifecycle marketing, ideally with early-stage startup exposure and limited resources.
• A demonstrated ability to discover a channel, validate it with data, and scale it effectively.
• A hands-on approach that favors doing the work personally rather than outsourcing it to agencies.
• Strong analytical judgment, with the ability to understand funnels and work confidently with data without losing sight of the bigger picture.
• A solid sense of brand, including positioning, storytelling, and the long-term value of strong creative work.
• Comfort moving between analytical work and creative review.
• Self-directed, resourceful, and able to make decisions and ship work despite ambiguity or incomplete information.
• Experience in consumer-facing environments is preferred, especially consumer apps, CPG, or consumer health; exceptional B2B marketers with consumer instincts are also welcome.
• Strong motivation to build a brand in mental health with the judgment and sensitivity the category requires.

Why This Role

This opportunity lets you help build a new kind of brand in culture, one grounded in how people actually feel rather than only in what they do or buy. You will shape the growth playbook for a category that does not yet have one, supported by a well-funded company and the freedom of a true 0-to-1 environment.

What We Offer

• The opportunity to join a close, motivated team working on a mission with meaningful real-world impact.
• Competitive compensation positioned at the top of the employee’s personal market range.
• Travel between the New York City and London offices.
• Standard startup benefits such as free lunch and coffee in the office, plus a generous learning budget.
• Coverage for personal therapy.

Additional Information

The company emphasizes autonomy, fast iteration, and direct execution. It expects the person in this role to be comfortable working across both brand and growth, operating with minimal structure, and helping define the playbook as the product and category evolve.
