The Three-Axis Growth Model separates expansion into range, geography, and channels. A brand first builds on retained customers, then tests an adjacent product vertical and proves that it can contribute meaningful revenue. It can next remove geographic buying friction through localization, such as local warehousing, once the business is large enough to handle the operational complexity. Finally, it broadens customer access and trust through an appropriate mix of ecommerce and physical retail. The model prevents growth from becoming an undifferentiated list of initiatives: each move belongs to a specific axis and should earn the next investment through evidence. Woodall summarizes Trinny London's growth as expanding its range, geographical reach, and channels after establishing strong cohorts and retention.

Core principles
- 01Retention creates the foundation for expansion
- 02Prove a new product vertical before adding another
- 03Localization removes friction only when operations can support it
- 04Physical and digital channels can reinforce each other
- 05Expansion should follow demonstrated customer demand
How to run it
- 1
Secure the customer base
Confirm that customers return and that earlier cohorts continue buying. Treat retention as the foundation rather than relying only on new-customer acquisition.
Pro tip Track cohort behaviour instead of only blended revenue growth.
Watch out Expansion built on weak retention behaves like quicksand.
- 2
Prove an adjacent range
Launch one product vertical that fits the customer relationship and measure whether it creates repeatable revenue. Wait for evidence before adding further verticals.
Pro tip Consider whether the new range has different replenishment economics.
Watch out Launching multiple verticals at once obscures what worked.
- 3
Remove geographic friction
Find markets where shipping cost, delivery time, or availability suppresses existing demand. Localize fulfilment only when the business can absorb the added systems and warehouse complexity.
Pro tip Look for markets with an existing audience before building local infrastructure.
Watch out Localization can require duplicated backend and warehouse operations.
- 4
Add complementary channels
Use retail, pop-ups, wholesale, or other channels to improve discovery and trust alongside ecommerce. Match the channel to how the target customer shops.
Watch out Do not enter a channel solely because investors or competitors expect it.
- 5
Rebalance the portfolio
Review which axis is producing profitable, supportable growth. Direct the next expansion toward the strongest evidence rather than stretching all three at once.
Pro tip Separate channel, geography, and range metrics so one cannot mask another.
In the wild
Woodall says Trinny London added skincare as a second vertical and reported that it reached roughly 35% of revenue after more than a year. The company also localized Australian distribution, which she says reduced shipping friction and increased Australia's revenue share, while retail added a physical presence.
→ The company pursued growth through an added range, localized geography, and broader channels rather than acquisition alone.
In this illustrative scenario, a coffee subscription with strong annual retention first tests equipment bundles, then adds local fulfilment in a country with costly shipping, and finally opens short-term tasting counters where its audience already shops.
→ Each expansion has a separate hypothesis and proof point.
Common mistakes
Expanding before retention
New ranges and markets magnify acquisition activity but do not repair a weak core customer relationship.
Ignoring operational readiness
Localization adds warehouses, integrations, and backend complexity that can overwhelm a business too early.
Stretching every axis together
Simultaneous range, market, and channel launches make causality and resource allocation difficult to judge.
Is it for you?
Best for
It is best for ecommerce brands with repeat customers and evidence that the core offer already works.
Not ideal for
It is not ideal for an unproven early-stage offer that has not yet established retention or product-market fit.
