Founding Marketing Lead in London

£40K-£60K base + meaningful founding equity
Hoxton, London. In-office 5 days a week.
This will be the hardest job you've ever had. We're hiring our Founding Marketing Lead. The person who owns brand, narrative, content, distribution, and growth end-to-end. We need someone in the room every day, who lives and breathes the company, and turns Letty into the first name anyone in property thinks of when they hear "AI." This is a founding hire. You build the function from zero. You'll own founder-brand and the B2B content engine for Letty.

Our starting point is selling to real estate agencies, where we're replacing manual workflows with AI employees that handle tenant engagement, landlord outreach, compliance, and maintenance autonomously. Property is one of the most important parts of people's lives, and the experience of buying, selling or renting one is still terrible. The industry is fragmented, compliance-heavy, and deeply inefficient. It runs on spreadsheets, missed calls, and manual processes that haven't changed in 30 years. Nobody has built the definitive AI agent layer for real estate yet. That's what we're doing. Your job is to make sure everyone in the industry knows it.

About us:
Backed by Entrepreneurs First and top-tier VCs
Live with agencies across the UK with early US traction
Building AI agents that don't just assist. They do the work.
Based in Hoxton, London. In-office 6 days a week.

What you'll do:

• B2B:
  • Build founder-brand for our CEO and CTO from a cold start. LinkedIn, X, podcasts, op-eds, conference stages.
  • Run the B2B content engine. Weekly cadence. Blog, social, video, weaponised content (data benchmarks, comparison cheat sheets, visual reports) that spreads inside the industry.
  • Ghost-write for our CEO. His voice, your craft. Three deliverables a week minimum.
  • Own PR. Build relationships with journalists and analysts who cover property, prop-tech, and AI. Get us in their stories.
  • Run customer marketing. Case studies, testimonials, reference programs, customer advisory boards.
• B2C:
  • Grow our B2C from zero to thousands of users through organic channels. Reddit, TikTok, Facebook groups, university housing pages, WhatsApp groups, wherever renters actually are.
  • Engineer viral loops on socials.
  • Build the B2C content engine. Different tone, different platforms, different cadence.
• Across both:
  • Own the brand. Voice, positioning, narrative, visual identity (in partnership with the Founding Designer).
  • Own the website end-to-end. Homepage, product pages, careers, blog. It's the front door, you make sure it sells.
  • Run launches end-to-end. Product launches, big customer wins, fundraise announcements. You orchestrate the moment.
  • Plan and run events. Industry conferences, our own dinners, founder roundtables.
  • Measure what matters. Demos booked from inbound, mind-share signals, B2C user growth, viral coefficient. Cut what doesn't work in two weeks.
  • Hire the next marketer and growth person when the time comes.

You'll be a great fit if:

• Strong writer. You write like a human, not a marketing deck. You can ghost-write for a founder convincingly.
• Strong taste. You can spot AI slop in three lines. You can spot a weak headline in three seconds.
• Built a brand or audience from cold. Not "managed" one that already existed. You wrote the post that took off, recorded the video, made the thing that spread.
• You switch registers. Writing for a 55-year-old branch manager on LinkedIn one hour, a 24-year-old renter on TikTok the next.
• Hands-on across the whole stack. Website, content, social, email, PR, events. You don't need to split the role.
• Commercially literate. You can measure what works and you do.
• AI-native. Cursor, Claude, Lovable, v0, every AI writing and editing tool that ships. You orchestrate, you don't draft from scratch.
• You move fast. First experiment shipped in week one, not week six.

We value taste, speed, and a maker's mindset over credentials.

Nice-to-haves:

• Founding or early marketing hire at a fast-moving B2B SaaS, AI, or fintech startup.
• Consumer marketplace or B2C growth background.
• You've grown a personal audience past 10,000 (Substack, LinkedIn, X, TikTok, podcast).
• You've ghost-written for a founder before.
• You speak to GenZ as a native and have shipped content before.

This role isn't for you if:

• Your first instinct is to hire an agency or go straight to paid ads.
• You think marketing is a deck of channel ideas you hand to someone else.
• You're a strategist who doesn't ship the work yourself.
• You've never written the thing that took off.
• You optimise for predictable hours or work-life balance.
• Six days a week in the office sounds exhausting rather than energising.

How we work:
We work hard. Six days a week, in-office, intense. We're rebuilding a $1T+ industry and we don't think that happens on a 9-to-5. We're also having fun. The team is sharp, ambitious, and genuinely enjoys the work. If "six days a week" sounds exhausting rather than energising, this isn't the role for you. And that's fine. We need people energised by intensity, not drained by it.

What we offer:
£40K-£60K base depending on experience
Meaningful founding equity. This is a founding hire and the equity reflects that.
Private health insurance
Uber home when you're working late
DoorDash dinners in the office
Monthly home clean
Brand new MacBook
But the real offer is ownership. You set the brand. You pick the channels. You write the content. You run the experiments. You hire the next marketer. No agencies, no proxies, no waiting for permission.

Interview process:
15-min screen with our Founder's Associate
30-min screen with the CEO
Take-home: brand audit of where we are today, a 30-day plan for B2B and B2C, and one piece of weaponised content you'd publish in week one (3 to 4 hours)
Office day. Walk us through your plan. Pair on a real launch we have coming up.
