Full-time Head of Marketing, Colossyan
FULL-TIME CMO JOB · SOFTWARE DEVELOPMENT SECTOR · GREATER LONDON, ENGLAND, UNITED KINGDOM

Colossyan, a 70-person AI training platform at Series A, is hiring a Head of Marketing (Growth) to own pipeline, paid acquisition, organic/SEO, and a three-person team reporting to the CEO. The appeal is a half-built marketing function with genuine strategic freedom; the catch is a full-time commitment with personal hands-on paid-account management (Google, LinkedIn, Meta) alongside leadership. No salary stated; hybrid London role with equity and benefits.
Full-time Head of Marketing — the balanced verdict
Why this role stands out
- Authentic greenfield opportunity — strategy 'genuinely unwritten', no legacy debt to unpick
- Reporting line to CEO and genuine end-to-end P&L ownership (pipeline, CAC, funnel)
- Team leadership (3 people now, hire next) with solo hands-on paid work keeps judgment calibrated
- Series A traction visible (1M+ videos, G2 Leader, Red Dot award, marquee customers); clear product-market fit
- Equity option, private healthcare, flexible leave, thoughtful benefits package
Worth checking before you apply
- No salary range disclosed; typical UK Head of Growth at Series A is £70–100k + equity but will vary by stage/funding
- Expectation that you personally run paid campaigns full-time is unusual for a head-of-level hire; could signal stretched budget or cultural emphasis on founder-level detail
- Three-person team and 'call on who joins next' implies you'll be hiring quickly into a nascent function

- Must-have
You have a real point of view on organic growth and on how AI search is changing it.
- Must-have
You have managed two to four people, including the parts nobody enjoys.
- Must-have
You are comfortable in both a self-serve funnel and an enterprise sales cycle, because we run both and they pull in different directions.
- Must-have
You report the number that went the wrong way before anyone has to ask.

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 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.

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.
