The role

We are in the process of acquiring a personalised memoir book platform as a new venture within the Wonderbly Group. The concept is simple and genuinely powerful: guided prompts help people capture their life stories, which are compiled into a beautifully printed hardcover book. A gift that becomes a family heirloom.

The platform has real traction. It has fulfilled tens of thousands of orders, built a subscriber base of over 150,000 people, earned an outstanding customer satisfaction rating, and shipped to customers in more than 80 countries. We’re acquiring it because we believe it is significantly underperforming its potential, and we want you to help fix that.

As a start this is a 6-month, 3-5 days/week contract but if you excel, it could evolve into a full-time role.

In the near term, your job is to maximise revenue from the existing platform, particularly through the gifting seasons ahead. The paid channels have been wound down, the CRM is underleveraged, and there is meaningful yield to extract from the existing customer base and audience. Then, as we redesign and relaunch the product in the new year, your role evolves: you become the commercial architect of the new experience, helping shape the go-to-market for the relaunch and help take it to its full potential.

What is exciting about this role:

• You are taking over a real business with existing revenue, brand equity, and a warm audience, not starting from zero.
• There is significant near-term opportunity to drive yield through channels that have been left largely dormant.
• You could be involved in shaping the product relaunch from the growth side, influencing what we build, not just how we sell it.
• The category is genuinely meaningful: helping families preserve their stories in a book that lasts forever.

What you will do:

Near term (now through early 2027):

• Reactivate and scale paid social, Google, and CRM channels on the existing platform.
• Drive customer acquisition and conversion through peak gifting seasons.
• Extract maximum value from the large existing email audience through structured lifecycle programmes.
• Build performance benchmarks and establish what actually drives acquisition, conversion, and repeat revenue.
• Run rapid creative and messaging experiments to sharpen what works.

Into 2027 and beyond:

• Feed growth insights and customer learnings into product and UX decisions for the relaunch.
• Develop the go-to-market strategy and execution plan for the new platform.
• Lead the migration of all existing users to the new experience, using it as a reactivation opportunity.

Who we are looking for:

You likely have 6 to 8 years in growth and hands-on performance marketing, ideally in a D2C or subscription environment. You have driven acquisition through paid social and digital channels, and you know how to turn an underperforming funnel into one that works.

More importantly, you have operated in situations where there was no clear playbook, where you had to test your way to answers, and where you took something underperforming and made it work.

You are someone who:

• Can move at pace in a situation that is not yet fully defined.
• Is as comfortable squeezing yield from an existing channel as testing a new one.
• Thinks naturally in hypotheses and experiments, not opinions.
• Combines creative instinct with analytical discipline.
• Cares about the product you are selling, not just the metrics around it.

What matters most:

• High agency: you thrive on autonomy, take ownership and do not wait for perfect direction.
• Clarity of thinking: you turn messy situations into simple, testable actions.
• Bias for action: you move fast, ship, and iterate.
• Resilience: you are comfortable being wrong often and learning quickly.
• Love for books and storytelling: this one is not optional.
• Fluency in AI-led marketing: you are genuinely excited by how AI is reshaping performance marketing, actively use AI tools in your work, and bring a point of view on where the biggest gains are.

Experience (guidelines, not a checklist):

• 4 to 8 years in growth or marketing, ideally in D2C, subscription, or early-stage environments.
• Experience running paid social and digital acquisition at meaningful scale.
• Proven track record of testing and scaling new ideas, not just optimising existing ones.
• Bonus: experience with lifecycle marketing and CRM (there is a large Klaviyo list that deserves proper attention).
