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 startedIf you enjoyed this episode, follow Behind the Design for more conversations unpacking the people, processes, and realities behind the design industry.Follow James McCarthy and GatherCohttps://www.linkedin.com/in/james-mccarthy-90a215140/https://www.gatherco.com.au/Follow Unfolded:https://www.unfolded.com.au/https://www.instagram.com/unfolded_Chapters03:02 — Why Gather Co Built a Trade-Only Supply Business06:00 — The Importance of Honesty & Long-Term Relationships07:12 — Fighting to Survive: The Early “Say Yes to Everything” Mentality10:30 — Why Strong Teams Matter More Than Founders Doing Everything12:27 — Learning to Love the Journey of Building a Business15:50 — The Story That Changed How Gather Co Worked With Clients20:12 — Why Boundaries & Policies Are Essential for Growth23:47 — Balancing Creativity, Timelines & Commercial Reality25:07 — Why Gather Co Chose Digital Over a Physical Showroom29:48 — Creating a Better Sample Process for Designers & Architects34:18 — The Mindset Shift That Turned Problems Into Competitive Advantages45:45 — Competition, Ego & the Fear That Still Drives Business GrowthKeywordsGather CoJames McCarthy Gather Cotrade supply businessscaling a supply businessbusiness growth mindsetentrepreneurship podcastdesign industry podcastinterior design businessarchitecture and design industrysupplier relationships in businessbusiness lessons for entrepreneurscreative business growthbuilding a trade-only businessonline showroom strategydigital-first business modelnatural stone suppliertrade-only supplier Australiabusiness operations and systemsfounder mindsetscaling a creative businessbusiness leadership lessonslong-term client relationshipsarchitecture supplier insightsdesign and construction podcastentrepreneurship in constructiongrowing a product-based business
