What does it really take to build a successful business without external investment?
Many founders are told that the route to growth is to raise funding, specialise in a niche, standardise everything and scale as quickly as possible. But what if there was another way?
In this episode of The Fractional CFO Show, Adam Cooper is joined by Gulliver Moore, Founder and CEO of Sunday Treat, a creative content agency that has grown organically into a multi-million-pound business working with some of the world’s best-known brands, including Google, Disney, Canon, Revolut and Candy Crush.
Over the last five years, Sunday Treat has expanded from a one-person operation into a team of fourteen, all without taking external investment and while deliberately ignoring much of the conventional advice given to agency founders.
Instead of focusing on aggressive scaling, Gulliver explains why they’ve prioritised building a financially sustainable business, maintaining a strong company culture, protecting creativity and making commercial decisions that support long-term growth.
This is an honest conversation about what building a modern agency really looks like behind the scenes.
Rather than talking about overnight success, we explore the realities of growing a business, managing uncertainty, improving leadership, forecasting revenue, maintaining healthy cash flow and building a company that founders genuinely enjoy running.
In this episode we discuss:
- Growing a creative agency without raising external funding
- Why cash flow is often more important than revenue growth
- Building a profitable business while staying true to your values
- The financial realities of running a project-based agency
- Managing working capital and large client payment terms
- Financial forecasting when future revenue is uncertain
- Scaling from founder to CEO
- Developing management and leadership skills
- Creating a culture that attracts and retains talented people
- Why Sunday Treat deliberately chose not to niche down
- How variety can become a competitive advantage
- Winning larger clients without following the traditional agency playbook
- Expanding into the United States and establishing a presence in New York
- Balancing creativity with commercial discipline
- Managing risk while continuing to grow
- Why sustainable growth often beats rapid growth
One of the themes that runs throughout the conversation is the relationship between creative ambition and commercial discipline.
Gulliver openly discusses how becoming responsible for employees completely changed the way he viewed leadership and business.
Like many founders, he discovered that being technically brilliant at your craft doesn’t automatically prepare you for managing people, having difficult conversations or building an organisation.
He talks honestly about the mistakes he made early on, the management books that transformed his approach and why learning to become a better leader has arguably been just as important as winning new clients.
For listeners interested in financial leadership, there are some particularly valuable insights into managing a business where revenue is inherently unpredictable.
Unlike subscription businesses or companies operating on recurring revenue, Sunday Treat works largely on individual projects.
That means forecasting income, managing utilisation, planning recruitment and protecting cash flow requires a very different approach.
Gulliver explains how they think about financial planning, why maintaining a healthy cash buffer has been critical to their growth and how they approach larger client projects where payment terms can stretch well beyond the point at which suppliers and employees need paying.
For founders, CEOs and business owners, it’s a practical reminder that profitability and cash flow are not always the same thing—and that sustainable businesses are built through careful financial management as much as strong sales.
The episode also explores one of the biggest debates in the agency world—whether businesses should niche down.
Conventional wisdom suggests agencies should specialise in one industry or one type of customer.
Sunday Treat deliberately chose not to.
Instead, they work across multiple sectors and platforms, helping brands create content for everything from LinkedIn and TikTok through to television advertising and global campaigns.
Gulliver explains why this approach has helped keep the team engaged, protected the business from changes within individual industries and ultimately created more opportunities for growth.
Another fascinating part of the discussion focuses on international expansion.
After seeing a significant proportion of revenue already coming from US clients, Sunday Treat recently established a formal presence in New York.
Rather than treating expansion as simply opening another office, Gulliver shares the commercial realities behind entering a new market, including client acquisition, pricing, building relationships overseas and balancing growth with operational simplicity.
Throughout the conversation, Gulliver offers a refreshingly honest perspective on what success looks like.
Rather than chasing vanity metrics or headline growth numbers, he talks about building a business that is enjoyable to run, financially resilient and capable of creating exceptional work for clients while providing meaningful careers for the team.
For anyone running a service business, creative agency, consultancy or founder-led company, there are practical lessons throughout this conversation around:
- Business growth
- Financial management
- Cash flow forecasting
- Profitability
- Leadership
- Founder mindset
- Scaling operations
- Agency growth
- Strategic decision making
- Commercial finance
- Business strategy
- Team development
- Company culture
- International expansion
As always, we finish with our Business Book Bonus, where Gulliver shares the books that have most influenced his leadership style, management approach and personal productivity—including Radical Candor, The Making of a Manager and Uptime.
Whether you’re a founder, CEO, agency owner, finance leader or someone interested in building a business for the long term, this episode is packed with practical insights and honest reflections from someone who’s grown a successful business by doing things differently.
