Head of Marketing

Fifth Dimension • New York, NY

1d • $225,000

About The Position

Fifth Dimension (5D) is an AI-native workflow automation platform purpose-built for real estate asset management and investment. We automate the complex, error-prone processes of collecting, analysing, and making decisions from disparate data sources across real estate document types — using a combination of specialised AI models tailored for real estate applications.
Founded by Kate Jarvis (CEO — Stanford PhD in linguistics and systems, with machine learning expertise) and Johnny Morris (Co-founder & CPO — 18+ years in real estate data, former Chief Data Officer), 5D is backed by tier-1 investors including Anthemis, Seedcamp, and Speedinvest. Our clients include some of the world's largest real estate firms across the US, APAC, and Europe, with the US and APAC as our primary growth markets. We are scaling aggressively toward $30M ARR.
We are a team of smart, humble, curious people who move fast and hold themselves to a high bar. We are looking for experienced operators who bring both strategic thinking and relentless execution.
We're hiring our first Head of Marketing to own and build 5D's marketing function from the ground up. This person will be a hands-on, high-hustle operator — not a brand strategist who delegates everything. You'll challenge every assumption about how marketing dollars are spent, find smarter ways to reach the right audiences, and build channels that generate real pipeline with creativity and commercial rigour. We don't have all the answers on what our marketing machine should look like — we're hiring you to own and shape it.
Our core markets are the US and APAC, and you'll need to build and scale marketing that works across both — understanding that buyer profiles, competitive landscapes, and adoption curves differ significantly between them. You will be responsible for building scalable, repeatable go-to-market engines across content, events, thought leadership, community, and digital channels — all in service of pipeline generation and brand authority in these markets. You'll also own how 5D is positioned in a market where AI-native platforms are still widely misunderstood by traditional buyers — ensuring our messaging cuts through the noise and lands with clarity at every touchpoint.
This could be your first Head of role — and we think that's a strength, not a risk. We want someone who's been the senior marketing manager or director who was the real engine behind the results, and is now ready to step up, own the function, and prove they can lead it. You'll have the support of an existing team of contractors and the opportunity to build out your team as you prove what works.
Your mandate is twofold. First, drive revenue growth now — build the marketing engine that fills pipeline with high-ACV prospects and helps close deals faster. Second, build the brand authority that makes 5D the obvious and only choice for real estate firms who are slower to adopt but represent massive long-term value. The largest institutional players (the CBREs, Knight Franks, and Greystar-scale firms) default to build-over-buy and move cautiously on technology adoption. Your job is to accelerate their FOMO and ensure that when they're ready, 5D is already the name they trust most.
This means you'll set the strategic direction — deciding which channels to invest in, which to kill, and how marketing resources are deployed against near-term pipeline versus long-term brand. You'll design the operational systems that make marketing repeatable and measurable. And you'll be hands-on in execution, especially in year one, building the playbooks and proving the models whilst scaling a team underneath you.

Requirements

• Operator mindset: You've built marketing channels or programmes from scratch at a high-growth B2B startup — as the senior manager of Head of who was hands-on doing the work, not directing it from above. This may be your first Head of role, and you're hungry to step up and own the function, or your next Head of role where you're excited by the opportunity to work at the forefront of AI for a fast growing, global business.
• US market experience: You've marketed B2B technology to enterprise buyers in the US and understand how to build a pipeline in this market.
• Pipeline obsession: Everything you do ties back to generating qualified pipeline and revenue. You understand that marketing exists to make the business money.
• Content at scale: You have direct experience running AI-assisted or high-volume content programmes, with a strong understanding of SEO, E-E-A-T, and content operations.
• Commercial rigour: There's real budget behind this role — 5D understands that winning in AI means winning now, and that requires investment to move fast. But you'll be expected to deploy that budget with discipline, thinking in terms of ROI, cost-per-lead, and cost-per-opportunity, not vanity metrics.
• Negotiation skills: Whether with event organisers, vendors, or partners — you drive hard but fair deals and know when it’s worth walking away.
• Comfort with AI tools: You use AI natively in your work — for content creation, research, outreach, and automation. You see AI as a force multiplier, not a gimmick.
• Pace and urgency: You move fast. You don't wait for permission. You ship things at 80% and iterate rather than pursuing perfection.

Nice To Haves

• Industry voice network: Experience cultivating relationships with analysts, thought leaders, or industry influencers in enterprise B2B or vertical SaaS — and leveraging those relationships to amplify brand reach among senior decision-makers.
• AI platform marketing experience: You've marketed an AI-native or machine learning product before and understand the unique challenges of selling cutting-edge technology to buyers who are still figuring out what AI means for their business.
• APAC market experience: Familiarity with marketing to enterprise buyers in APAC — understanding the different adoption curves, buyer profiles, and competitive dynamics across the region.
• Real estate or proptech familiarity: What matters most is your ability to quickly learn a vertical and speak credibly to a sophisticated buyer — but existing knowledge of real estate is a strong advantage.

Responsibilities

• Own the marketing contribution to pipeline targets, with clear accountability for the volume of qualified opportunities marketing delivers each month across all channels — inbound content, events, outreach, webinars, and digital campaigns.
• Design and run demand generation campaigns — including webinars, gated content, email nurture sequences, and retargeting — that move prospects through the funnel toward qualified conversations, with tracked intent signals throughout the funnel.
• Build and optimise the MQL-to-SQL handoff process in partnership with sales, ensuring leads are properly scored, enriched, and routed so sales teams spend time on the highest-value opportunities.
• Drive up MQL-to-SQL conversion rates through better targeting, lead nurturing, intent spotting and tighter feedback loops with AEs on what's converting and what isn't.
• Design and execute ABM programmes targeting a defined universe of high-value accounts across the US and APAC — the institutional real estate firms, asset managers, and investment platforms where deal sizes justify a precision approach.
• Partner with sales to build account-specific marketing plays: personalised content, targeted outreach, multi-threaded engagement across stakeholders, and coordinated campaigns timed to deal progression.
• Develop account intelligence and intent-based targeting to prioritise marketing effort where it will have the most commercial impact.
• Measure ABM effectiveness at the account level — tracking engagement, pipeline influence, and deal acceleration rather than just lead volume.
• Arm the sales team with the materials they need to win: battle cards, competitive positioning docs, case studies tailored to specific buyer personas etc.
• Build a library of objection-handling content that helps AEs accelerate early adopter deals and navigate the concerns of conservative institutional buyers.
• Work closely with AEs to understand what's working in live deals and what's not, feeding those insights back into content, messaging, and campaign design.
• Build and run a scalable content engine that drives organic traffic and keyword authority — using AI-assisted production to achieve volume without sacrificing quality.
• Own keyword research, competitor analysis, and content topic identification to ensure every piece of content serves a strategic purpose.
• Manage the end-to-end content publishing process — from editing and formatting through to scheduling, posting, and reporting.
• Identify, pitch, and secure speaking appearances at conferences aligned with our ICP across US and APAC markets — proactively and at scale, not waiting for inbound invitations.
• Build strategic partnerships with industry bodies, technology platforms, and media outlets that raise 5D's visibility and credibility — co-hosted events, joint research, co-branded content, and shared platforms that position 5D alongside trusted names in real estate and AI.
• Professionalise and scale 5D's broader events presence — self-hosted dinners, workshops, hackathons, and community events that position 5D as the default choice in real estate technology.
• Turn every event into pipeline: prospect attendees against ICP criteria, run pre-event outreach, and coordinate with sales to ensure marketing-driven events deliver high ROI by directly supporting high-ACV deal progression.
• Support and amplify the Founders’ LinkedIn presence as a primary thought leadership and pipeline-generation channel, and develop a broader social content strategy across the team.
• Cultivate relationships with real estate industry voices, analysts, and thought leaders who can authentically amplify 5D's message to senior decision-makers.
• Own competitive messaging and positioning — ensuring 5D is clearly differentiated from point solutions and generic AI tools in all external-facing content.
• Ensure that when the whales who might not be ready to take AI seriously just yet come round to the idea, you’ve made 5D top of mind.
• Own marketing performance metrics and report regularly on MQL volume, MQL-to-SQL conversion, pipeline contribution, content performance, event ROI, and channel effectiveness etc.
• Build dashboards and tracking systems to make marketing's impact on revenue visible across the business, without high effort manual lifts.
• Continuously test, learn, and iterate — treating marketing as a data-driven function, not a creative services department.
