Marketing Lead

Founding Marketing Leader, Agentic AI Security

You’ll build out and own marketing at an early-stage agentic AI security company, founded by a team who have built and exited businesses before and backed by high-profile investors. You’ll create a small, AI-first marketing function that puts the business at the front of a new category. This is a step up for a Head of Marketing or Director of Marketing who wants to grow into a company-wide marketing leadership role, reporting to the CEO and joining as part of the founding team.

The essentials

• Reporting to the CEO, as the first dedicated marketing leader
• Suited to a current Head of or Director of Marketing ready for their next step
• Central London, hybrid, with 2 to 3 days a week in the office
• £80k - £130k base, plus founding-team equity

What you’ll actually do

• Build out and own day-to-day marketing, adopting an AI-first approach and working closely with the founding leadership team.
• Build AI-first, top-of-funnel demand generation using HubSpot, Clay, Apollo, Semrush and in-house AI agents.
• Create searchable content for a global audience, with most go-to-market effort in the US, so the company shows up in the right searches, including AI search.
• Own analyst relations with Gartner and Forrester, and award entries, aiming for leader status as the category forms.
• Run a focused calendar of thought-leadership events, not standard trade shows.
• Grow a small specialist team, possibly including a US-based Product Marketing Manager.

What you’ll need

Essential

• Marketing experience at a Cyber Security product company selling to large enterprises.
• Strong digital and data skills, and you enjoy getting hands-on with marketing technology and AI.
• A track record of demand generation that builds pipeline with Sales.
• The ability to explain a technical product clearly to less technical buyers.
• Experience leading a small team, or clear readiness to step up and build one.
• A real desire to grow, a willingness to roll your sleeves up and get things done, and comfort adjusting plans as priorities change.

Nice to have

• Experience in AI security, identity and access management or a similar area.
• Helping to shape a new category, including work with analysts.
• Marketing to US audiences or regulated industries such as financial services.
• Building a challenger brand against larger competitors.

What’s in it for you

• Building marketing from the ground up, without legacy processes or politics, with a role and team that grow as the company grows.
• An AI-first stack already in place, with the freedom to change it. You’ll enjoy working hands-on with AI and building your own agents to make marketing run better.
• The whole team together at least quarterly, plus a budget for conferences, courses, books and gear.
