Marketing Lead – Be Part of the Next Big Thing in Fintech

About Sidekick

We’re Sidekick - a digital wealth platform reimagining how ambitious individuals build financial security and long-term wealth.

Our mission is simple: make wealth-building tools once reserved for the ultra-rich available to everyone. Whether it’s high-yield savings, professionally managed investment portfolios, or the ability to borrow against your investments without selling, Sidekick is putting powerful financial tools in the hands of professionals, founders, freelancers, and tech-savvy doers.

Since launching in 2022, we’ve already grown to £125M in assets under management, and our ambition is bold: to scale to £1B in AUM within the next two years.

We’re now looking for our first Marketing Lead to join the leadership team and define how we tell our story, connect emotionally with customers, and build a consistent growth engine that scales.

Why This Role Matters

This is not about big budgets and external agencies. This is about building a repeatable, scalable marketing machine from the ground up. You’ll be Sidekick’s first marketing leader, shaping the strategy, getting hands-on with execution, and proving what works, before growing a team around you.

We want someone who knows what it’s like to build in the digital wealth space, has seen what works at scale, and can bring a playbook for mass-market growth. You’ll be as comfortable digging into customer data as you are creating campaigns, testing new channels, and telling a brand story that customers trust.

What You’ll Do

• Define and own Sidekick’s marketing strategy, building the foundations of a scalable acquisition engine.
• Collaborate with stakeholders across the business to drive growth – not just advertising but more holistic growth activities.
• Be hands-on in executing campaigns across digital, partnerships, referral, and community channels.
• Identify ways growth features can be incorporated in the product.
• Build and scale a referral-led growth model that leverages networks and trust, not just paid spend.
• Shape Sidekick’s brand story, connecting emotionally with customers and cutting through a crowded market.
• Identify, test, and deliver new partnership opportunities that create credibility and distribution.
• Use data and customer insights to inform decisions, optimise funnels, and drive consistent, reliable growth.
• Over time, recruit and develop a small marketing team to scale initiatives.
• Act as a key voice in the leadership team, influencing product, customer, and commercial strategy.

Who You Are

• Experience joining a company at Series A or early growth stage, and building marketing from scratch.
• Proven ability to acquire and retain mass-market financial services customers at scale.
• Hands-on operator - you execute campaigns yourself, not just direct agencies.
• Strong track record in referral, partnership, and network-led growth.
• Data-driven and analytical, comfortable owning acquisition funnels and optimisation.
• Storyteller with the creativity to craft a brand narrative that resonates emotionally with customers.
• Commercially sharp - accountable for results, growth, and ROI.

Why Join Sidekick?

Game-changing mission - We’re bringing wealth-building power to the masses, not just the 1%.

Career-defining opportunity - Build and scale a marketing function from scratch at a high-growth fintech.

Backed to win - Well-capitalised and laser-focused on smart, sustainable growth.

People who get it - Work with a driven, supportive founding team with fintech pedigree.

What We Offer

• Competitive startup salary + meaningful equity.
• The opportunity to build and own the marketing function at a pivotal stage in our growth.
• Unique chance to play a defining role in Sidekick’s journey to £1B AUM.
• Collaborative, ambitious culture with room to innovate.
• An extra day off for your birthday

In summary: This is a role for someone who wants to build the marketing engine of a fast-scaling digital wealth platform - bringing the playbook, the creativity, and the execution needed to deliver Sidekick’s next stage of growth.
