Who We Are

Armstrong Wolfe is a COO Advisory Firm

I have long believed in the untapped potential of the COO platform and wondered how best to release its potential. I have established relationships with a myriad of COOs over 25 years from across the industry, from all backgrounds, all nationalities and possessing a wonderful diversity in experience.

Armstrong Wolfe was established to unite and galvanise this talent, to offer the COO an independent and confidential way to hold meaningful cross industry conversations in a trusted, confidential Chatham House Rule environment, where we sought to mobilise the COOs and direct the dialogue to help them release this potential.

Key to this success has been the behavioural and characteristics of the overwhelming percentage of COO community, being decent and principled and seeking to do the right thing.

Many of the challenges allocated to the COO are non-proprietary and it is this we look to exploit to the benefit of all.

More so, if we can do this successfully relating to business matters, we can most certainly extend this spirit of collaboration and cooperation into charitable causes and to collectively work towards addressing inequalities.

It is our mission to enable this to happen.”
