A list is not a claimant book
You have the names. What you don’t yet have is the journey that turns them into registered, validated participants — and the system that holds them through the years a case takes.
Most teams start with a spreadsheet, a mail merge and good intentions. At fifty thousand claimants, that becomes the operational risk.
The data is the starting point. The programme is the work.
Four ways a good list still fails
None of these are legal problems. All of them are visible in the data long before they become terminal.
No journey behind the data
Contact details exist; registered participation does not.
Manual process at scale
Spreadsheets and shared inboxes become the operational risk.
No single claimant record
The same person looks different in every system and the numbers never reconcile.
Silence between milestones
Claimants hear nothing for months, then don’t respond when the case needs them.
One system. Three operating modes.
CasePartners™, LeadPartners™ and ArbPartners™ are not three products. They are three configurations of the same Participation Operating System™ — the same infrastructure, the same claimant record, the same governance.
One question resolves the mode: do we need to build a claimant book?
CasePartners™
The data already exists. Your team holds the book; Mediatasks provides the participation infrastructure that turns it into registered, validated claimants.
You build the bookLeadPartners™
No claimant data. Mediatasks builds the book — national acquisition, registration and engagement — then runs it through to settlement readiness.
Read the mode →ArbPartners™
US mass arbitration. Acquisition, operations and arbitration-ready filing at campaign scale, on a performance basis.
Read the mode →A mode change is a configuration, not a migration.
Scope of service
The participation system
What the claimant moves through.
- Participation strategy
- Registration journey design
- CRM implementation and configuration
- Automation and workflow
- Email and SMS communications
- Dashboard reporting
Operations & enablement
What keeps your team running it well.
- Eligibility validation and data quality
- Claimant engagement programme
- Compliance support
- Operational playbooks
- Team coaching and training
- Continuous optimisation
What you hold, what is reachable, what is provable — assessed against the eligibility criteria before anything is sent.
Data audit and participation plan.
The claimant’s route from first contact to a complete, evidenced registration — designed, built and tested.
Journey map and the live registration flow.
One claimant record, configured to the matter and to the firm’s reporting needs.
Configured CRM and a single claimant record.
Email, SMS and workflow built once, so contact happens on schedule rather than when someone remembers.
Contact calendar and message library.
Eligibility screening and cleansing applied at intake and maintained through the life of the case.
Screening rules, rejection log, clean record.
Scheduled contact through the quiet years, including recovery of dormant and unresponsive cohorts.
Engagement schedule and re-engagement report.
Your team trained on the system, with written operating procedure for every recurring task.
Operational playbooks and a trained team.
Registration, validation and engagement measured weekly against the case timetable.
Programme dashboard and weekly report.
Two paths. One finish line.
Both operating modes converge on settlement. CasePartners™ starts at stage 01 because the book already exists.
LeadPartners™ begins two stages earlier.
Research and national acquisition are the book build. Everything from registration onward is identical in both modes.

A claimant’s value isn’t measured at signup. It’s measured when they reach the finish line.
Two ways to run it
Not every team is in the same position. Some want the system and the training; some want us to operate it. The right model is the one that fits the firm.
Every legal decision remains with instructed counsel. We provide the systems, capacity and delivery infrastructure through which those decisions are executed at scale.
Done with you — platform & support
Your in-house team runs the day-to-day programme. Mediatasks provides the platform, configuration, onboarding, training and ongoing operational support.
Best for: teams with claimant-operations capacity that need the right infrastructure, not full outsourcing.
Commercial model: platform fee plus a performance element aligned to programme outcomes.
Done for you — managed operations
Mediatasks operates the participation programme end to end. Your firm focuses on legal strategy and case decisions.
Best for: teams without the capacity to run a claimant operation alongside the litigation.
Commercial model: managed-service fee with performance alignment.
Both models run on the same platform and infrastructure. Firms move between them as the programme scales.
Who it’s for
- Firm type
- Legal teams holding claimant data; membership bodies, trade associations and unions acting for members; stichtings and claim foundations.
- Case type
- Opt-in matters with an identified population; opt-out CAT proceedings and representative actions where no bookbuild is required yet.
- Jurisdiction
- UK (CAT, GLO) · EU (WAMCA, RAD). US mass arbitration runs through ArbPartners™.
- Data position
- Client databases, customer records, email lists, mobile numbers, disclosed datasets.
- Not a fit
- Matters where the claimant population must first be found — see LeadPartners™.
31%
of a claimant population that had been written off entirely were re-engaged. The firm’s own engagement rate with that group was zero.
Worked on a performance basis alongside a leading steering committee firm in one of the UK’s largest diesel emissions cases. Documented return on investment to the firm: 2,606%.
Questions of substance
Do we have to replace our case management system?+
No. CasePartners™ sits alongside it. The case management platform holds the legal file; the participation layer holds the claimant journey. We connect the two rather than replacing either.
Is this software, or a service?+
Both, and deliberately so. Software alone leaves the operating burden with your team. The platform comes with the configuration, the playbooks and the people who know how to run it.
Our data is old and partly wrong. Is that a problem?+
It is the normal starting point. The data assessment establishes what is reachable and what is provable before any contact is made, and cleansing runs continuously from that point.
Who talks to the claimants?+
Your firm, in your name, under your compliance position. We design the communications and operate the system that sends them; sign-off stays with the legal team.
What if we later need to build a book?+
The programme expands into LeadPartners™. Same platform, same claimant record, no migration — the acquisition stages are added in front of what already runs.
Who owns the data?+
The firm. Data protection roles, retention and processing terms are agreed in writing before the programme goes live.
