Client Reviews
From Our Clients
"The distribution review identified a channel overlap we'd suspected but never quantified. The final report gave us a clear basis for a difficult conversation with one of our long-standing partners. That wasn't easy, but it needed to happen."
Thomas Chan
General Manager · Kwun Tong, HK
March 2025
"We had been putting off the governance conversation for two years. Sophie worked patiently with the family — including my father, who was sceptical — and eventually we reached a structure that everyone felt was fair and workable. I hadn't expected the process to feel so measured."
Patricia Lau
Director · Family Office, Central HK

"The lean workshop was grounded in observations from our own floor, not in textbook examples. The team came in two days before the workshop and spent time with our supervisors, which made a visible difference in how the content landed. Our team left with something they could actually use."
Raymond Wong
Operations Director · Tuen Mun, HK

"Martin spoke Cantonese with our logistics partners during the site observations, which made a real difference. Some of our older staff wouldn't have been as candid in English-only interviews. The data that came out of those conversations was more accurate because of it."

Supply Chain Manager · Tsuen Wan, HK

"The fixed fee was important to us. We've had poor experiences with hourly billing that escalated beyond what was budgeted. Knowing the cost before we started meant we could get internal approval without caveats, which actually sped up the decision to proceed."
James Kwan
CFO · Sheung Wan, HK

"We came to gantwellm because the problem we were trying to solve was genuinely specific to our situation — not a generic challenge. What I appreciated was that they didn't try to map it onto a standard framework. They worked out what our situation actually was and built the recommendation from there."

Managing Director · Wan Chai, HK

In Detail
Three Case Studies
The Challenge
A Hong Kong consumer goods importer was running three separate regional distributors with overlapping territories in Kowloon and the New Territories. Margins were compressing and service levels were inconsistent, but the company had no clear view of where the inefficiency originated.
What We Did
Over four weeks, the team mapped all three distribution channels by territory, SKU category, and margin layer. We interviewed each distributor's operations teams and conducted logistics cost modelling across the three networks. Channel overlap was quantified for the first time.
The Outcome
The client renegotiated one distributor agreement, consolidating territory coverage. Within two quarters, logistics cost-per-delivery fell by an estimated 14% and service level reporting became consistent. The managing director described the report as the first time the data had been assembled in one place.
"We knew something wasn't working. gantwellm told us precisely what." — General Manager
The Challenge
A second-generation family in Hong Kong had accumulated significant assets across property, listed equities, and a privately held manufacturing business. Decision-making was centralised in the founder, with no documented investment mandate, no formal governance, and increasing friction as the third generation began expressing interest in involvement.
What We Did
Over a four-month retainer, we facilitated family council sessions, developed a draft investment mandate across the three asset classes, designed a governance charter, and structured a programme for third-generation involvement that was acceptable to the founder. All in English and Cantonese.
The Outcome
The family adopted a governance charter and investment mandate in month five. Third-generation members joined a formal observer programme. The founder described the process as clarifying decisions that had been deferred for more than a decade. The retainer has continued on a quarterly review basis.
"These were conversations that needed a neutral party to be possible." — Family Director
The Challenge
A Tuen Mun-based light manufacturing company had heard of lean production but had no structured understanding of where waste existed in their process. Line managers were resistant to external consultants and the MD wanted a format that would build internal capability rather than create dependence on outside advisers.
What We Did
David spent two days on the production floor before the workshop, mapping two representative production lines and speaking with supervisors in Cantonese. The three-day workshop was built around those two lines. Post-workshop support focused on a single kaizen event chosen by the internal team.
The Outcome
The internal team ran their first unsupported improvement cycle within six weeks of the workshop. The kaizen event selected by the team reduced changeover time on one line by approximately 22 minutes per shift. Three supervisors who had been sceptical became active advocates for the methodology.
"The sceptics became the advocates. That was the real result." — Operations Director
