Senior Marketing Manager

Slingshot AI

Slingshot AI is the team behind Ash, the first AI designed for mental health. Our mission is to make support more accessible and help people change their lives in the ways they want.

We're building a world-class team by empowering individuals with the autonomy, flexibility, and support they need to do their best work. We dream big, iterate fast, and care deeply. If that sounds like you, we'd love to hear from you.

Our team spans machine learning, product, engineering, conversational design, clinical, growth, and operations, with offices in both New York City and London.

We're a well-funded Series A company, having raised $93M from Andreessen Horowitz, Radical Ventures, Forerunner Ventures, plus top-tier tech investors involved in ElevenLabs, Captions, Shopify, Plaid, Notion, Canva, Twitch, Airtable, and many others.

The Role

Ash is going from 0 to 1, and the shape of our growth is still being written. We don't yet know which mix of channels will build this category: word of mouth, paid, social, experiential, partnerships, clinical referrals. Your job is to figure that out.

This role will get to work on a lot across marketing. You'll work across the business (think brand, growth, and product) to identify opportunities, test them quickly, read the data honestly, and double down on what works. One month that might mean activating a brand campaign. The next, it might mean building a referral loop, fixing onboarding messaging, or turning clinicians into a growth channel no one else has cracked.

A note on how we work: we love doing the work ourselves, so we can get good at it. That means fewer agencies, and a lot faster feedback. You'll be hands-on across everything, writing the copy, building the campaign, setting up the experiment, pulling the numbers. A true jill (or jack) of all trades. You'll partner closely with others on our marketing team, our Head of Marketing, and our founders. You won't have a big team or a big playbook. We value creativity, moving quickly, learning fast, and out of the box thinking. The right person comes up with ideas today and tries them today. You can probably use Claude Code to build things, and have true builder energy.

What You'll Do

Discover and test growth channels. Develop hypotheses about where demand for Ash comes from, design fast experiments across paid, organic, social, experiential, referral, and partnership channels, and use analytics to decide what deserves more investment.

Activate brand campaigns. Plan and run integrated campaigns roughly every two months, working with our social lead and creative partners. Define the activation strategy: what we say, where it shows up, and how it connects to the product experience.

Own the funnel. Understand how users discover, try, activate, and stick with Ash. Identify where messaging, onboarding, lifecycle, and monetization can improve, then ship the fixes.

Turn insight into action. Talk to users, review research, and analyze behavior. Translate what you learn into positioning, product recommendations, and the next round of experiments.

Build the learning machine. Create the measurement and feedback loops that let us know what's working within weeks, not quarters, so the whole company learns faster.

Invent new demand. Some of our best channels don't exist yet. Doctors and therapists could become advocates. Communities could become distribution. You'll find the unconventional paths and make them real.

What We're Looking For

• 3 to 5 years across growth marketing, brand marketing, integrated marketing, or lifecycle, ideally including an early-stage startup where you had to do everything with limited resources
• A track record of finding a channel, proving it with data, and scaling it
• Builder, not delegator: you've done the work yourself rather than managing agencies to do it, and you prefer it that way.
• Strong analytical instincts: you live in the numbers without getting lost in them, and you can read a funnel cold
• Genuine brand sense: you understand positioning, storytelling, and why creative quality compounds
• Left brain and right brain: equally comfortable in a spreadsheet and a creative review
• Scrappy and self-directed: you run with ambiguity, make decisions with incomplete information, and ship
• Consumer experience strongly preferred (consumer app, CPG, or consumer health); exceptional B2B marketers with consumer instincts considered
• Excited to build a brand in mental health, with the judgment and care that category demands

Why This Role

You'll help shape a new kind of brand in culture, one grounded in how people actually feel, not just what they do or buy. You'll define the growth playbook for a category that doesn't have one yet, with the resources of a well-funded company and the blank canvas of a true 0 to 1.

What we offer:

• A chance to join a passionate tight-knit team working on something to change the world
• Competitive compensation (top of personal market)
• Travel between our NYC / London offices
• Usual startup perks like free lunch and coffee in office + generous learning budget
• We cover your personal therapy
