Freelance B2B Marketing Manager

Freelance | Remote | Europe working hours | 20–25 hours per week

Please apply only if you have hands-on B2B technology marketing experience and operate and freelancer.

This contract freelancer role is not suitable for B2C marketers, social media managers, virtual assistants, general marketing coordinators or candidates whose experience is primarily with e-commerce or consumer brands.

GTM Advantage is a Swiss boutique go-to-market agency working with founders and leadership teams of European B2B technology companies.

Our clients have strong products and early market traction but need more structured marketing execution to build visibility, credibility and a scalable commercial engine.

We define the go-to-market direction and work closely with our clients to turn priorities into practical marketing activity. Our work includes founder thought leadership, product launches, website messaging, customer stories, email campaigns, sales enablement, webinars and marketing operations.

We are looking for an experienced freelance B2B Marketing Manager to support the delivery of client projects over the long term.

This is a hands-on delivery role for an established independent professional. It is not intended as temporary work between permanent positions.

You will work closely with the founder of GTM Advantage, who leads client strategy, positioning and overall project direction.

Your responsibility will be to turn agreed priorities into high-quality marketing deliverables, coordinate execution and keep projects moving forward.

You will not be expected to independently define and deliver an entire go-to-market programme. You will contribute ideas, challenge assumptions and take ownership of your areas of delivery while working within an agreed strategy and scope.

Depending on the client and project, your work may include:

• Creating LinkedIn content for B2B founders, executives and company pages.
• Turning interviews and expert insights into credible thought-leadership content.
• Supporting product launches with coordinated LinkedIn, website, email and sales-support activity.
• Writing and editing website pages, landing pages and email campaigns.
• Developing customer stories, case studies, presentations and sales materials.
• Repurposing webinars, demos and technical content into commercial assets.
• Supporting webinar promotion, coordination and follow-up.
• Maintaining campaign plans, CRM information and marketing documentation.
• Coordinating designers, developers, video editors and other specialists.
• Reviewing client-facing work for accuracy, clarity and consistency.
• Managing timelines, approvals, tasks and follow-ups.
• Using AI tools to improve research, content development and delivery workflows.
• Improving GTM Advantage templates, systems and delivery processes.

This role is suited to someone who already works professionally as an independent freelancer or contractor and wants to build a stable, long-term collaboration with a growing consultancy.

You should be comfortable managing recurring client work, issuing invoices and reserving consistent weekly capacity.

Please do not apply if you are primarily looking for a temporary freelance project while searching for a permanent role.

You should have:

• At least 5 years of relevant B2B marketing experience.
• Hands-on experience with B2B technology, SaaS, AI, deep-tech or other complex solutions.
• Experience working with startups, scale-ups or small international teams.
• Strong experience writing LinkedIn content for founders, executives or B2B brands.
• Excellent written and spoken English.
• Strong editing skills and the ability to turn technical input into clear, commercially relevant content.
• Experience with websites, landing pages, email campaigns and customer stories.
• Experience using a CRM such as HubSpot, Pipedrive or Salesforce.
• Practical experience using AI tools for research, content creation or workflow improvement.
• Strong project management and organisational skills.

Experience primarily limited to B2C, e-commerce, influencer marketing or general social media management will not be sufficient for this role.

• An established freelancer committed to independent work as a long-term career.
• Reliable, responsive and accountable for deadlines.
• Proactive without working outside the agreed direction.
• Comfortable receiving strategic guidance and translating it into execution.
• Able to ask strong questions when information or priorities are unclear.
• Detail-oriented and careful with client-facing materials.
• Comfortable working directly with founders and senior stakeholders.
• Able to manage several client workstreams without losing quality.
• Commercially aware and able to connect marketing activity with business objectives.
• Comfortable working in an environment where client priorities may evolve.

• Experience with European B2B technology scale-ups.
