41. Scaling a Trade Supply Business with GatherCo

Finished homes, polished brands, and resolved details are what we usually see. What’s less visible is the pressure underneath: the hard decisions, constant judgment calls, and the reality of sustaining growth.

James McCarthy knows that reality well.

In this episode of Behind the Design, I sit down with James McCarthy, co-founder of GatherCo, a trade-only supplier in the architecture and interiors industry known for its relationship-led approach, adaptability, and willingness to do things differently.

What began as a small business trying to stay afloat has grown into a trusted supplier working with architects, designers, and builders across Australia. But this conversation is less about polished success and more about what sits behind long-term growth.

We talk about the early pressure to say yes to everything, why boundaries become essential as a business matures, and the mindset shift that comes with realising not all growth is good growth.

We also explore sustainable scaling, how partnerships evolve, and why understanding your lane is one of the most important lessons for founders.

In this episode, we also covered this: — Why saying yes to every opportunity early in business eventually becomes unsustainable — The lesson that completely changed James’ perspective on business challenges and competition — How Gather Co built trust with architects and designers through honesty and long-term thinking — Why the business chose not to follow the traditional showroom model and what happened instead — The importance of boundaries, systems, and internal accountability as a team grows — What founders often misunderstand about scaling a product-based business — How small businesses can use adaptability and speed as competitive advantages — The reality of managing client expectations, timelines, and decision fatigue within the design industry — Why relationships remain at the centre of everything Gather Co does — The emotional side of entrepreneurship and the importance of remembering why you started
