Partnership Approach

We believe in long-term partnerships, not transactions. By working consultatively and with discretion, we ensure our services are aligned with each client’s objectives. This approach enables us to act as an extension of our clients’ teams: responsive, reliable, and focused on outcomes.

Our Values & Legacy

Founded as a specialist prime broker, Linear has evolved into a multi-solution investment services firm. What has never changed is our commitment to collaboration, accountability, and accessibility. These values underpin our culture and shape the way we deliver value to clients every day.
