Upskilling Your Clients and Building a Culture of Experimentation
Key Takeaways
- Measure both quantitative results and emotional impact when evaluating client outcomes
- Use discovery techniques like the five whys to uncover the real needs behind a client request
- Offer training as a complementary service to enhance client implementation and long-term retention
- Apply the GROWS framework - Gather, Rank, Outline, Work, Study - for systematic experimentation
- Aim to increase client experimentation velocity by 2-5x to drive faster innovation
- Build teams with completer-finishers to balance idea generation with execution
In this episode of the Agency Journey podcast, David Arnoux shares what Growth Tribe has learned from training over 35,000 professionals across 1,000 companies in digital growth skills. His perspective on agency value delivery is distinctive: the best way to keep clients is to make them more capable, not more dependent.
David argues that agencies that train their clients alongside delivering services create stickier relationships, better outcomes, and a more defensible position in the market. The conversation covers practical frameworks for building experimentation cultures inside client organizations and how agencies can use skills development as a differentiator.
The GROWS Framework for Experimentation
David introduces the GROWS framework as a structured approach to running experiments systematically. The five stages are Gather ideas, Rank by potential, Outline the experiment, Work on execution, and Study the results. The value of the framework is not complexity but consistency - running experiments the same way every time allows teams to improve the process itself, not just individual tests.
For agencies, introducing this framework with clients serves two purposes. It creates a shared language for how improvement happens, and it builds client capability so that good work can continue between agency engagements. David’s goal at Growth Tribe is to help clients increase their experimentation velocity by two to five times - more tests per unit of time means faster learning and faster growth.
Removing Complexity Rather Than Adding Tools
One of David’s counterintuitive points is that the agencies most skilled at helping clients experiment are the ones that remove complexity rather than add more tools and processes. The instinct in a growth engagement is often to introduce new platforms, new frameworks, and new dashboards. But the constraint in most organizations is not access to tools - it is the discipline to run a clean experiment, study the result honestly, and apply the learning.
David emphasizes building teams with what he calls completer-finishers: people whose strength is not generating ideas but driving those ideas through to completion. Most teams are overloaded with ideators and underequipped on execution.
