About Steven Bartlett Private Office

The team behind Steven Bartlett’s ventures - driving innovation across media, marketing, investment, and technology.

Role Mission

Somewhere in the UK right now, there's a brilliant founder talking themselves out of an idea because they don't have access to the right network, capital or resources. We're starting an initiative that changes that, backing high-potential founders from lower socioeconomic backgrounds. This role sits within Steven Bartlett's private office and philanthropy pillar, marketing our most impactful initiatives and accelerating the growth of his soon-to-launch nonprofit. You won't be maintaining an existing audience, you'll be building from zero and expanding to change the lives of 10,000 people over the next 5 years.

Key Outcomes

• Own the end-to-end marketing funnel strategy, from discoverability and awareness through to long-term loyalty and advocacy
• Split focus across two distinct audiences: beneficiaries (via social, SEO/AEO and newsletter) and supporters, including mentors, donors and brand partners (via CRM and newsletter marketing)
• Hands-on content creation from day one, writing, editing and producing long-form, short-form, video, static image and newsletter content
• Establish and guard tone-of-voice and brand consistency as we scale and layer in AI to drive content volume
• Track performance across the funnel and turn insights into experiments: what's converting, what's leaking, what to test or grow next

Core Competencies

• Strong generalist marketer with real end-to-end funnel experience, from SEO/AEO and landing pages through organic social to newsletter and long-term nurture
• A hands-on creator who can write, edit and produce content directly across formats, not just direct the process
• AI-native, using AI tools to execute strategy and produce content at pace, and to help shape our in-house AI marketing tooling over time
• Strong platform fluency, with proven experience building social presence and engagement across platforms and audiences
• Experience with lifecycle/CRM marketing: segmentation, journeys, automation
• Data-driven, confident making decisions from experimentation rather than gut feel, and reporting on engagement metrics

Key Outcomes

• You want your creative work to do something that matters
• You're energised by ambiguity and don't need a detailed brief to get started
• You think in funnels and outcomes, not posts and impressions
• You're comfortable being the only marketing hire in the room
• You believe AI is a creative force multiplier and want to prove it, while protecting the human judgement that makes a brand trustworthy

Ideal Background

• Experience in startups, media brands, accelerators, charities or community-led businesses
• Familiarity with Hubspot, GA4, Claude, Canva, Webflow
• Experience scaling teams and marketing resource
• Experience in events and community marketing
• Experience in comms and PR
