Head of Marketing in London

Most corporate training is still made the way it was made twenty years ago. Someone books a studio or opens a legacy authoring tool, spends six weeks building a course, and it is out of date by the quarter after it ships. Every large company knows this and almost none of them have a way out.

Colossyan is the agentic platform for training and enablement. Our AI agents draft videos and full interactive courses from a company's own source material, and a human stays in control of everything that ships. Paramount, Continental, Cisco, Johnson & Johnson and UPS use us to turn what they already know into training their people actually finish. Nearly a million videos have been created on the platform, we are a G2 Leader in both AI Video Generator and Course Authoring, and we are a Series A company of just over 50 people across London and Budapest.

The role Marketing here is about half-built. There is a team of three, an organic engine publishing every week and ranking for terms that matter, paid running across Google, LinkedIn and Meta, and pipeline arriving from both self-serve signups and enterprise sales. None of it is mature, and the pieces do not yet add up to a system. That is the appeal. The strategy is genuinely unwritten, and whoever writes it will not have to unpick five years of someone else's decisions first.

You will own growth end to end and report to the CEO. You will also keep running paid acquisition yourself, because we want a leader whose judgment is still calibrated by doing the work.

• What you'll own:
• The pipeline number, across self-serve and enterprise. You set the targets with us, then you hit them.
• Paid acquisition, personally: Google, LinkedIn, Meta, and the CAC that comes out of them.
• Organic growth: SEO, content, and how AI assistants answer questions about our category.
• Conversion across the funnel, and the handoff where the self-serve motion meets the sales motion.
• Product marketing: positioning, launches, and the messaging sales carries into the room.
• A team of three, and the call on who joins it next.

• What we're looking for:
• You have carried a pipeline number at a B2B SaaS company, for long enough to know what happened to it. In practice that tends to mean six years or more.
• You have built and run paid accounts yourself, recently enough that you would back your own judgment over an agency's.
• You have a real point of view on organic growth and on how AI search is changing it.
• You have managed two to four people, including the parts nobody enjoys.
• You are comfortable in both a self-serve funnel and an enterprise sales cycle, because we run both and they pull in different directions.
• You report the number that went the wrong way before anyone has to ask.

• Nice to have:
• Time at a performance agency or a high-volume growth team before going in-house; launching into new markets; work somewhere near AI, content creation, L&D or HR tech.

• What we offer:
• Stock options: We want everyone to feel motivated to do their best work, which is why we're all owners.
• Remote work: Enjoy extra flexibility with one full week of remote work per quarter.
• Free lunch Thursdays: Build team connections over complimentary weekly lunches, available for both in-office and remote employees.
• Wellness Wednesdays: We know working at a startup can be mentally tough, which is why we offer monthly expert-led sessions on meditation, yoga, and other well-being practices.
• Great office location: Work from our centrally located, pet-friendly office designed for comfort and team collaboration.
• Birthday time off: Celebrate your birthday with an additional paid day off, if it falls on a weekday, separate from your regular vacation allowance.
• Flexible annual leave: Enjoy 25 days of annual leave with the unique option to convert the 8 bank holidays into working days and boost your annual leave allowance to 33 days. Choose what works best for you.
• Private healthcare: Access private healthcare through Bupa, including talk therapy and physiotherapy. We understand that everyone does their best work when they're happy and healthy.
• Retirement planning: We offer matched salary sacrifice pension with Smart Pension.
• Cutting-edge AI technology: Be at the forefront of AI innovation, working directly with state-of-the-art AI technologies that form the core of our product.
• Impact: As a rapidly expanding Series A startup, your contributions will have an immediate impact on our global development.
