Job description

Aldgate, London. In-office 5 days a week.

We're hiring our Founding Marketing Lead. The person who owns brand, narrative, content, distribution, and growth end-to-end.

This is a founding hire. You'll build the marketing function from zero and be responsible for making cinnamon the first company people in property think of when they hear "AI."

You'll work closely with the founders every day, turning what we're building, what we're learning from customers, and where the industry is going into content and campaigns that people actually care about.

You won't be managing agencies or sitting behind a strategy deck. You'll write the posts, shape the narrative, run the launches, make the content, test the channels, and work out what actually moves the business forward.

What we're building

Property is one of the most important parts of people's lives. It's where you raise your kids. It's most people's biggest financial decision. And the experience of buying, selling, or renting one is still shockingly bad.

We live in a world where you can send money across borders in three seconds, hail a car with a tap, and have your entire medical record on your phone.

But when it comes to property? You're waiting for a call back from a branch that closes at 5:30. Your offer is being managed in a spreadsheet. Your tenancy renewal is stuck because someone forgot to send an email.

The infrastructure that powers how people find homes, move between them, and manage their biggest asset has barely changed in 30 years.

Nobody has built the definitive AI agent layer for real estate yet. That's what we're doing.

cinnamon.io is a platform of AI employees that handle the property transaction end to end.

Our first AI hire is already live with number of agencies across the UK. But we’re just getting started.

About us

• Backed by Entrepreneurs First and top-tier VCs (our first investor was early investor into Canva)
• Live with agencies across the UK with early US traction
• Based in Aldgate, London.

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.
• Own PR. Build relationships with journalists and analysts who cover property, prop-tech, and AI.
• Run customer marketing. Case studies, testimonials, reference programs, customer advisory boards.

What is yours to craft:

• Own the brand. Voice, positioning, narrative, visual identity (in partnership with the Founding Designer, and fractional CMO).
• Own the website end-to-end. Homepage, product pages, careers, blog.
• Run launches end-to-end. Product launches, big customer wins, fundraise announcements.
• 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.
• 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 without making them sound like everyone else on LinkedIn.
• 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, video editing, PR, events.
• Commercially literate. You can measure what works and you do.
• You're genuinely customer and product obsessed. You care whether branch staff actually use cinnamon every day. Customer pain isn't just something to manage, it's something to understand deeply.
• 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, filmed, built, or shipped the thing yourself
• You optimise for predictable hours or work-life balance
• Five days a week in the office sounds exhausting rather than energising

How we work

We work hard. five days a week, in-office. 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.

What we offer

• Meaningful founding equity
• Private health insurance
• Wellhub Gym/Wellness plan
• Dinners in the office
• 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.
