About Approach Portfolio Team Contact

Case origination. Project management. Global reach.

We originate and structure
cross-border litigation projects.

BlueStream Projects identifies strong claims and assembles the teams that take them forward: the lawyers, the experts and the funding partners each case needs.

Members of our team have played leading roles in some of the largest group actions in English legal history. We know what these cases demand because our people have been through them.

We also work alongside law firms and other partners on matters they originate. Where a project needs cross-border coordination, specialist input or a funding solution, we help assemble the right team and structure.

Strong claims. Rigorous selection.
The right team.

01

Origination

Our network spans six languages and multiple jurisdictions. We originate directly and work with partners whose standards match our own.

02

Assessment

Every case undergoes independent counsel review. We look for a credible legal basis, supporting precedent, a clear theory of damages and a defendant who can pay.

03

Funding

We work with established litigation funders and sophisticated investors to structure the funding each project needs. Those arrangements typically cover legal fees, experts, investigations and court costs.

04

Cross-border Coordination

We build each project around strong substantive law and a forum with predictable, efficient procedures, then work with lawyers and specialists in the relevant jurisdictions to coordinate the legal, expert and funding work. Members of our team have played leading roles in the cases that shaped English law on cross-border group claims.

Cases that matter.

Our portfolio spans claims concerning environmental damage, corporate misconduct, human rights violations and data misuse. Each project is selected for legal strength, commercial viability and the prospect of meaningful accountability.

Commercial value and accountability
are not in tension.

Our projects concern allegations of environmental damage, human rights abuses and corporate misconduct. Deforestation. Industrial pollution. Forced labour. Data misuse. We choose claims that are legally strong, commercially viable, and whose outcomes matter.
