Fractional /Permanent - Head of Growth - Startup - Agentic AI - B2C / Social Media

My client is an early-stage startup building one of the category-defining consumer agentic AI products — an AI that takes action on users' behalf, not just answers questions. We've proven early product-market fit and are now hiring our first Head of Growth to turn that early traction into a repeatable growth engine.

Location: UK South East. Commutable to Central London for regular meetings with founders.

This is a true startup builder role : no legacy playbook, no big-company machine behind you — just a small team, real product traction, and a blank-canvas mandate to build brand, content, community, and growth from scratch.

What you'll own

🔹 PLG engine — activation, retention, referral loops, and lifecycle marketing that make the product itself the primary acquisition channel

🔹 Social-first brand — a distinct, culture-native voice across TikTok, Instagram, Snapchat, X, YouTube Shorts, and Reddit (not corporate AI-speak)

🔹 Content &​ creator engine — demos-as-content, use-case storytelling, and an influencer program tied to real signup numbers

🔹 Team build-out — hire and lead a lean marketing org as we scale through our next funding round

What we're looking for

🔹 A proven track record launching a B2C mobile app — you've taken a consumer app in the UK &​ EU from early traction to real scale and can point to the specific playbook, numbers, and channels behind it

🔹 Hands-on experience building an organic social engine across TikTok, Instagram, Snapchat, and other leading platforms, with measurable growth to show for it

🔹 Genuine comfort operating in early-stage startup ambiguity — this is a builder role, not a maintainer role

🔹 Excellent product &​ data &​ metrics analytics and fluency

🔹 Deep understanding of UK-first and wider European B2C markets — consumer behaviour, platform dynamics, and go-to-market nuances across the region

🔹 Excellent written and on-camera communication

🔹 AI-native product experience, a personal following or reputation in tech/AI, experience scaling a marketing function through a funding round, community-led growth chops (Discord/Reddit).

This is a fantastic opportunity to be part of a launch of an exciting life changing app and help build and grow
