This is a founding growth hire at an early-stage company, and it suits a specific profile: a high-calibre, early-to-mid-career growth operator who has already helped a B2B software startup scale, and who is now ready to own the function outright.
We are looking for someone still deep in the doing. You will be the person writing the landing page, building the campaign, joining the sales call and reading the funnel data — not managing a team that does it.
The company
We are working with an early-stage AI software business building automation technology for a large, traditional and underserved B2B market.
The company’s software helps service-led organisations automate operational workflows, improve responsiveness and reduce manual workload. It is already working with early customers, has a strong founding team, significant investor backing and ambitious plans to scale.
This is a rare chance to join early, own growth end to end, and build the commercial engine from the ground up.
Candidates must be based in the UK with full right to work — no sponsorship available.
The role
The Growth Lead / Senior Growth Marketing Manager / Demand Generation Lead will be the first growth hire, working directly with the founders and the sales team to define positioning, build demand, generate qualified demos and create a repeatable growth engine.
The core outcome is simple: build a reliable engine for qualified pipeline in a B2B software market.
You will:
- Define and sharpen the positioning, messaging and narrative for a sceptical, time-poor B2B buyer
- Build the demand generation engine from scratch across paid, organic, events, content, outbound-supporting marketing and founder-led channels
- Own the funnel from first touch through to qualified demo, sales handover and pipeline tracking
- Identify the right ICPs, buyer personas, channels and messaging to drive commercial traction
- Speak to customers directly, sit in on sales calls, and turn what you hear into sharper campaigns
- Build campaigns that create demand in a market where buyers are wary of overhyped AI products
- Produce landing pages, email campaigns, sales collateral, product messaging and campaign assets yourself
- Work with the founders on founder-led growth, thought leadership and category education
- Support events and conferences, from messaging and promotion through to follow-up and pipeline attribution
- Measure channel performance, conversion rates, qualified demos, pipeline and revenue impact
- Test, optimise and scale paid, ABM, email, content and event activity
- Work closely with sales and customer success to improve conversion, handover quality and feedback loops
- Use LLMs, AI tools and automation to raise the quality and speed of your own execution
- Write the early growth playbook, and help shape the team that comes after it works
What we’re looking for
- A strong academic record from a leading university (or equivalent institution). This matters to the client.
- Direct experience in growth marketing, demand generation or GTM inside a B2B SaaS, B2B software or fast-growth startup. Startup or scale-up environment specifically — not corporate, not agency-only.
- Evidence that you helped a company scale: pipeline, demos, opportunities, ARR, revenue, or another measurable commercial outcome you can talk through in detail.
- Experience building from a low or early base, rather than optimising an already-working machine.
- Hands-on delivery across several channels — paid social, paid search, ABM, email, landing pages, events, content, founder-led growth or lifecycle.
- A clear grasp of how positioning, messaging and customer insight translate into revenue.
- Experience working shoulder-to-shoulder with founders, sales, customer success or product.
- Excellent written communication — the ability to make a complex product feel simple and obvious.
- High agency and genuine comfort with ambiguity. Nobody will hand you a plan.
- Real interest in AI, with hands-on use of LLMs, workflow automation, agents, Custom GPTs or similar.
This is probably not for you if you are
- Primarily a content, social, brand or PR marketer
- A sales, business development or partnerships profile
- An agency-side performance marketer without in-house B2B startup experience
- A corporate marketer without early-stage experience
- A CMO or VP-level leader who now works through a team rather than doing the work directly
The package
- £80,000–£130,000 base salary depending on experience, with flexibility for exceptional candidates
- Significant equity participation
- Genuine ownership and influence at the earliest stage
- London office, 4 days per week
The opportunity
This is a chance to become the founding growth hire at an ambitious AI software startup attacking a large, traditional and underserved market.
You will own growth from the ground up, define how the company talks about itself, build the demand engine, work directly with the founders, and have a visible effect on the commercial direction of the business.
It will suit someone who has already helped one B2B startup grow, and now wants to do it again — earlier, with more ownership and considerably more upside.
