The case theory holds. The execution doesn’t
Firms may have strong case theories, experienced counsel and viable respondent targets, and still face significant execution challenges once claimant volumes begin to scale. Building and managing the infrastructure that large claimant populations require is expensive, resource-intensive and difficult to execute well.
For many firms the challenge is not managing claimants once they arrive. It is identifying, acquiring, qualifying, onboarding, engaging and retaining enough claimant volume to support a campaign at all.
That is where ArbPartners™ sits.
Four ways a viable campaign stalls
Mass arbitration has matured quickly as a legal strategy. The infrastructure supporting many campaigns has not.
Volume outruns the operation
Intake capacity, not case merit, sets the ceiling on the campaign.
Qualification breaks at scale
Eligibility checks that work at five hundred claimants fail at fifty thousand.
Files aren’t arbitration-ready
Records exist; the documentation a filing actually requires does not.
No halfway house
Firms either outsource everything, or build the whole operation from scratch.
One system. Three operating modes.
ArbPartners™, CasePartners™ and LeadPartners™ are not three products. They are three configurations of the same Participation Operating System™ — the same infrastructure, the same claimant record, the same governance.
ArbPartners™ is the US mass arbitration configuration: the claimant lifecycle plus arbitration-ready preparation and filing.

Two ways to work together
There is currently no halfway house in US mass arbitration: firms either outsource everything or build from scratch. ArbPartners™ offers both — full-service delivery, and a platform model for firms that want to run their own operation with the right infrastructure behind them.
We are not a traditional vendor. Our returns are tied to campaign outcomes, not to time spent or services billed. We succeed when the campaign succeeds.
Full-service delivery
ArbPartners™ manages the entire campaign operation: acquisition, registration and onboarding, communications, data quality and eligibility verification, arbitration-ready preparation and filing, campaign oversight and reporting. Your firm focuses exclusively on legal strategy and case decisions.
Best for: firms that want to deploy a proven operational machine without building one in-house.
Commercial model: performance-based — we earn when the campaign succeeds.
Platform & support
Your in-house team runs the day-to-day campaign. ArbPartners™ provides platform access and configuration, setup, onboarding and team training, campaign infrastructure and filing tools, data quality and eligibility systems, ongoing coaching and performance monitoring.
Best for: firms with in-house teams that need the right infrastructure and tools, without full outsourcing.
Commercial model: platform fee plus a performance element aligned to campaign outcomes.
Both models are built on the same platform and operational infrastructure. Firms that start with Done With You frequently move to full-service delivery as campaign scale increases — the transition is direct, because the underlying system is identical.
Who it’s for
- Firm type
- Plaintiff firms, funders and partners running high-volume mass arbitration campaigns.
- Campaign type
- Consumer, employment and product claims subject to enforceable arbitration agreements.
- Jurisdiction
- United States only (Rule 23 and mass arbitration). UK and EU matters run through LeadPartners™ or CasePartners™.
- Position
- Counsel instructed and respondent targets viable; claimant volume is the constraint.
- Not a fit
- Matters where legal strategy, not participation, is the bottleneck.

Questions of substance
Are you a law firm?+
No. ArbPartners™ is not a law firm, claims broker, lead generation vendor or litigation funder, and it does not provide legal advice or legal services. It is participation infrastructure operated on the firm’s instructions.
Who decides which claims are filed?+
Instructed counsel, always. ArbPartners™ does not determine which claims should be filed. Once counsel instructs, claims can be filed at scale through the platform.
How does a performance-based model actually work?+
We take on execution risk alongside the firm. Our return is tied to campaign outcomes rather than to hours or services billed. The specific structure is agreed per campaign and set out in the programme specification.
We already have an in-house team. Is this still relevant?+
Yes — that is the Done With You model. Your team runs the campaign; ArbPartners™ provides the platform, configuration, training, filing tools and operational support behind it.
Can we change model mid-campaign?+
Yes. Both models run on the same platform and infrastructure, so moving from platform-and-support to full-service delivery is a change of who operates the system, not a change of system.
Who owns the claimant data?+
The firm. Data protection roles, retention and processing terms are agreed in writing before the campaign goes live, and firms retain full authority over their claimants at all times.
