Senior Marketing Manager

About the Company

Slingshot AI is the organization building Ash, an AI product created specifically to support mental health. The company’s purpose is to make help easier to access and to support people in making meaningful changes in their lives.

The team is focused on giving people autonomy, flexibility, and the backing they need to do excellent work. They move quickly, experiment often, and care a great deal about the outcomes they create.

The company works across machine learning, product, engineering, conversational design, clinical, growth, and operations, with offices in New York City and London. It is also a well-capitalized Series A business backed by $93M from investors including Andreessen Horowitz, Radical Ventures, and Forerunner Ventures, along with other prominent tech investors.

Role Overview

This is a hands-on marketing leadership role focused on helping Ash find and scale the channels that will drive its next stage of growth. The category is still being defined, so the successful candidate will need to identify what works through rapid testing, thoughtful analysis, and decisive execution.

You will work across brand, growth, and product to uncover opportunities, run experiments quickly, interpret results honestly, and double down on the tactics that move the business forward. The role may involve launching brand campaigns, building referral systems, improving onboarding messaging, or exploring unconventional growth paths such as clinician advocacy.

The team prefers to build things internally rather than outsource them, which means this position is highly execution-oriented. You will be expected to write, build, launch, measure, and refine campaigns yourself while working closely with the Head of Marketing and the founders. The environment rewards creativity, speed, curiosity, and a strong builder mindset.

Key Responsibilities

Your core focus will be discovering, testing, and scaling growth channels, while also improving the overall marketing and product funnel.

• Formulate hypotheses about where demand for Ash can come from, then run quick experiments across paid, organic, social, experiential, referral, and partnership channels.
• Use performance data to identify the channels worth expanding and the ones that should be dropped or improved.
• Plan and execute integrated brand campaigns approximately every two months, coordinating with the social lead and creative partners.
• Define how campaigns connect messaging, placement, and the product experience.
• Take ownership of the funnel, from discovery through activation and retention, and improve messaging, onboarding, lifecycle, and monetization where needed.
• Interview users, review research, and analyze behavior to translate insights into positioning, product recommendations, and future experiments.
• Set up the measurement and feedback systems that help the broader team learn quickly and continuously.
• Explore unconventional routes to demand generation, including advocacy from doctors and therapists or community-driven distribution.

Requirements

• 3 to 5 years of experience in growth marketing, brand marketing, integrated marketing, or lifecycle marketing, ideally including work at an early-stage startup.
• A proven ability to identify a channel, validate it with evidence, and then scale it effectively.
• Comfort building and executing work directly rather than relying on agencies or other intermediaries.
• Strong comfort with analytics and funnel performance, including the ability to interpret data without losing sight of the bigger picture.
• Clear understanding of brand positioning, storytelling, and the cumulative value of strong creative work.
• Balanced strength in both analytical and creative thinking.
• A self-directed, resourceful approach that works well in ambiguous environments and helps move ideas from concept to launch quickly.
• Experience in consumer-facing businesses such as consumer apps, CPG, or consumer health is strongly preferred; outstanding B2B marketers with consumer instincts may also be considered.
• Interest in building within the mental health space, with the judgment and care that category requires.

Why This Role Stands Out

This position offers the opportunity to shape the growth strategy for a new category, backed by strong funding and a largely blank slate. You will help define the marketing playbook for a brand that aims to stand out in culture by focusing on how people genuinely feel, not just on behavior or purchases.

Benefits and Offerings

• Opportunity to join a close-knit team working on a mission with meaningful real-world impact.
• Competitive compensation positioned at the upper end of the individual market.
• Travel between the New York and London offices.
• Typical startup benefits, including complimentary lunch and coffee in the office, plus a generous learning budget.
• Coverage for personal therapy.
