Evidence before claims
Method, context and limitations stay with the conclusion.
About Wesley D. Petzer
Technical curiosity with commercial consequences.
South African-born and Netherlands-based, Wesley works across cultivation systems, commercial strategy, market transition and input economics.
The perspective
Crop, channel, relationship and economics belong in the same conversation.
Petzer Consulting exists for the work that falls between conventional categories: technical products that need a market, markets that need local proof, and operators whose cultivation decisions carry commercial weight.
Wesley’s working range moves from specialist retail and grower education to facilities, distributors, commercial teams and leadership. The common thread is translating field reality into a decision people can own and repeat.
The approach is independent, evidence-led and deliberately practical. Where a fact is date-sensitive, it is dated. Where a result is contextual, the context stays attached. Where specialist legal or technical sign-off is required, the boundary is made visible.
