Founding Growth Lead, London

The real-assets industry runs on fragmented systems, disconnected data and a huge amount of manual work. At Fifth Dimension, we’re building the decision intelligence platform for real-assets investors and managers, helping teams move faster, surface better insight and make more confident investment decisions.

We’ve recently raised a $26M Series A led by HV Capital and are expanding across the US and APAC.

Now we’re hiring our first dedicated Growth Lead. Not to ‘run marketing’. To help us figure out how enterprise growth should actually work here. We’re at the stage where there’s real momentum, but still plenty to build.

We’re looking for someone who enjoys creating structure, improving systems and helping turn early GTM signals into a more scalable growth engine.

We’re looking for a hands-on, highly analytical and highly executional Growth Lead to help us build and scale our enterprise demand generation motion.

You’ll work across outbound, nurture, events, lifecycle, growth experimentation and experimenting with ABM growth tactics to help us reach the right enterprise buyers in the right way. You’ll partner closely with sales to build repeatable systems, improve funnel visibility and help define what scalable pipeline generation should look like at Fifth Dimension.

This is a great role for someone who enjoys building from the ground up. We have momentum, customers and a clear market opportunity, but we’re still early in how our growth function operates. You’ll be joining at the stage where there is plenty to figure out and improve.

You’ll need to be comfortable switching between strategy and execution, and genuinely skilled at translating strategy into an executable plan. You understand how individual tactics fit within a larger strategic framework, no random acts of marketing. One day you might be mapping nurture journeys in HubSpot. The next, you might be analysing funnel conversion data, refining outbound logic, improving event follow-up or helping shape GTM priorities.

You’ll have built strong marketing foundations the traditional way, and you now know how to set up AI workflows that deliver real efficiency, with the right human oversight to maintain quality. We care far more about ownership, operational thinking and execution than polished corporate marketing playbooks.

We don’t believe channels should be fixed in advance. This is a Growth role: we’d expect you to bring hypotheses, run experiments and use whatever channel mix proves most effective, rather than being constrained by a predefined playbook. Frameworks like Crossing the Chasm are useful and there are real lessons to take from them, but they aren’t the only lens on our market. We’re cautious about assuming traditional technology adoption models map neatly onto AI adoption, so we want someone who brings experience and frameworks but is equally willing to test assumptions and adapt based on what they’re seeing in the market.
