Job description

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

We are seeking a Creative Strategy Lead to join the Slingshot AI marketing team. Reporting to our head of growth, your job is to identify, create, test, and scale our D2C creative motion. Millions of people already use general purpose AI as a therapist, and millions more are on a waitlist or priced out of care. Demand is not our problem. Getting Ash in front of the people who need it is. Creative is the biggest lever we have on that, and this role owns it.

This is a hands‑on role by design. You own the loop, coming up with creative copy, producing visuals and tag‑lines, and iterating quickly to dial in on what works. You are building the engine that gets Ash in front of people. You create and test fast, trust your instincts, and want to develop the playbook that puts proper mental healthcare at the world's fingertips.

Key responsibilities:

• Own the weekly experiment loop: hypothesis, A/B test, read the result, identify winners, iterate. This is the spine of the role and where taste shows up.

• Build the system that makes it repeatable. Testing cadence, angle library, naming and tagging, and a bank of real user language pulled from communities, reviews, and our own conversations.

• Create winning concepts and then raise the hit rate of winning concepts so paid has more to scale behind. The bar is quality, not volume, and you manage what we spend proving things out.

• Write the hooks, headlines, overlays, and scripts, in the voice of the person scrolling.

• Brief at volume: one brief that many creators each interpret their own way, built for what each network rewards rather than resizing one idea for all of them.

• Coach creators with sharp feedback, one to many. You brief and evaluate and if required can do creator ops, supporting in producing the content yourself.

• Work with media buying on a weekly cadence. You read media buy KPIs and go into the buying tools yourself to check how tests performed, and you know buying well enough to challenge the buyer on their own ground.

• Develop the product and audience understanding that decides what works. When AI makes output cheap, this becomes the deciding factor in paid.

• Set the visual and verbal point of view for Ash in market. We do not look like the rest of this category, and we do not intend to start.

About you:

• You produce assets yourself on the AI stack, Figma, CapCut and the rest. Not in front of the camera, but you make the creative for testing, not just brief it.

• You come from the paid side moving into creative, or creative moving toward paid. Both work. What matters is turning product and audience understanding into creative that wins.

• Experienced in writing performance copy; have taste and can quickly iterate

• Consumer only, ideally subscription. If your background is SaaS, this is not the role.

• You can set up a clean test, say in advance what would prove you wrong, read the result honestly, and defend your taste with an argument rather than a mood board.

• You want to work on mental health for a reason you can say out loud.

Nice to have:

• You can challenge our media buyer on their own ground, because you have done the buying yourself.

• You have built or reshaped web funnels and landing pages to match the creative that drove the click.

• You have built or run a creator or UGC pipeline, including sourcing, briefing, and quality control.

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
