Head of Growth, London
Join Fifth Dimension as Head of Growth. Own GTM strategy, experiment with new routes to market and shape our next stage of growth. Reporting to our CEO. London. £100k–£140k + bonus + equity.
About us
Fifth Dimension helps real-assets investors and managers turn complex documents and data into intelligence they can use to make better decisions. We've raised a $26M Series A led by HV Capital and are expanding across the US and APAC.
We're hiring a Head of Growth to shape our next stage: choosing where we compete, defining how we reach and win the right customers, and building a growth function that can scale with the business.
What is the role?
Reporting to Kate, our Co-founder and CEO, you'll own our growth strategy and work with the founders and leaders across sales, product and customer success to translate it into a clear go-to-market plan. That means making choices about which customers and use cases to prioritise, what makes our proposition compelling, and where we invest time and money.
Your remit spans the customer journey, from awareness and demand through to conversion, adoption and expansion. You'll own growth's contribution to qualified pipeline and revenue, and work with the relevant teams to address the biggest barriers to growth wherever they sit.
We're still testing how best to take our product to market. You'll bring a strong bias towards experimentation: form clear hypotheses, get focused tests into market and use what you learn to sharpen our strategy. We want someone who brings informed ideas about what could work and is willing to change direction when the evidence points elsewhere.
This is a leadership role with real building to do. You'll spend time with customers, interrogate the numbers, develop the proposition and get promising ideas into market. You'll also decide what to stop, where to focus and which capabilities we need next.
What you'll do
Own a growth strategy and go-to-market plan tied to company revenue goals
Identify the segments, buyers, use cases and markets with the strongest opportunity, and make clear decisions about sequencing and investment
Work with customers, sales and product to sharpen our positioning, messaging and evidence of customer value
Build a prioritised programme of GTM experiments across target segments, messaging, channels and sales approaches
Define what each experiment should teach us and how we'll judge it, using customer feedback and commercial signals appropriate to our sales cycle
Decide what to scale, adapt or stop, and use those decisions to shape our mix of outbound, inbound, content, events, partnerships and account-based programmes
Partner with sales on opportunity quality, buying-group engagement and conversion, and with product and customer success on adoption, expansion and customer advocacy
Set growth targets and connect activity and spend to qualified opportunities, pipeline progression, revenue and acquisition efficiency
Establish a regular GTM review with leadership so that insight turns into decisions and clear priorities
Build the growth function, coordinating execution and proposing the budget, hires and external support needed for the next stage
What we're looking for
You've probably:
Set and delivered growth or GTM strategy for an early-stage or scaling B2B software business, with evidence of your contribution to pipeline and revenue
Built a growth function or established a new route to market while the approach was still being figured out
Made consequential choices about target customers, positioning, channels and resource allocation, and can explain what changed because of them
Worked closely with enterprise sales teams through long sales cycles and complex buying decisions
Designed and tested different GTM approaches, learned from unsuccessful or inconclusive results, and turned promising findings into repeatable ways of winning customers
Worked across customer insight, positioning, demand generation and funnel performance, with enough practical depth to evaluate execution and get directly involved
Used CRM and commercial data to diagnose growth problems and guide decisions
Applied AI and automation to GTM with sound judgement about quality, customer experience and human oversight
Aligned founders and functional leaders around shared priorities and taken responsibility for delivery
You're probably someone who:
Thinks commercially and connects growth decisions to business outcomes
Brings a strong bias towards experimentation and is willing to change their mind
Can make focused decisions with incomplete information, then improve them as evidence emerges
Moves comfortably between setting direction and making things happen
Takes ownership of problems and follows through on the results
Challenges assumptions constructively and brings people with them
Enjoys learning directly from customers as much as interrogating the numbers
Brings original ideas and the discipline to test them
Bonus points for experience in:
Taking enterprise software to institutional investors, funds or asset managers
Helping enterprise buyers adopt a new category of technology
Developing GTM approaches across international markets
This role may not be for you if…
You want to inherit an established GTM approach with the major decisions already made
You prefer to set strategy and hand off responsibility for its results
You're looking to focus on a single marketing channel
You need a large team in place before you can make progress
You're uncomfortable testing your assumptions or changing direction when the evidence warrants it

About Fifth Dimension
We're building the AI platform that powers every real asset decision.
Leases, financial models, data rooms, investment memos - for decades, the people making billion-dollar calls have done it with Excel, PDFs, and an analyst working late. We're changing that. 5D turns the most complex documents and data in finance into structured intelligence that professionals actually trust.
We're a Series A company with offices in London, New York, and Singapore, working with the firms that finance and manage the built world. That's every skyscraper, data centre, wind farm, and bridge - in the $393 trillion real assets market. We help them drive alpha, close faster, and make better calls. We ship daily, building a product that compounds: every data source, every skill, every customer correction makes the platform more powerful than the last.
Johnny and Kate founded 5D from a shared frustration. Johnny spent 17 years inside institutional real estate, close enough to the problem to know exactly where the pain was. Kate spent 12 years building enterprise software, close enough to know what it would take to fix it. They started 5D because no one else was doing it right, and they still run it that way: demanding, direct, and genuinely excited about what they're building.
The decisions 5D powers shape cities, funds, and careers. We're direct with each other, high on craft, and genuinely invested in each other winning, and we build better for it. If that's the kind of place you want to spend your time, let's talk.
