Built on expertise. Focused on results.
Sinclair James was founded on a simple belief: the biggest constraint on business growth is almost always people.
Not strategy. Not technology. Not market conditions. The quality of the leaders in the right seats.
We work with businesses who have the ambition to grow and know that the team around them needs to evolve to get them there.
We help them understand what's holding them back, map the leadership they need, and find the exceptional people who will deliver it.
Every business has a ceiling - a point where the people and processes that built it are no longer enough to grow it.
We exist to help businesses break through it.

James Plant founded Sinclair James after 12 years recruiting across Formula 1, automotive, aerospace and advanced manufacturing - from technical specialists through to C-suite leaders.
He brings a background in motorsport engineering to a business built on the same principles F1 teams apply to performance: precision, the right person in the right seat, and an obsessive focus on outcomes.
James understands that every business has a ceiling - a point where the people and processes that built it are no longer enough to grow it. His job is to help businesses identify that moment, and find the exceptional leaders who take them through it.
