Pros
US team operated efficiently and worked together closely and effectively. Small team but cohesive and aligned, and just generally great team with great people.
Cons
UK office was a mess - exec management did not seem to be aligned, and therefore organizationally focused on the wrong things, ultimately setting all up to fail (globally). Financial acumen does not exist in C-Suite, driving poor objectives for all levels of the organization and ultimately leading to (more than one) downfall, with many people's jobs as the fall out.
