Fourth Party AINeutral by design
Fourth Party AI
Dispute Resolution and Claim Administration Just Entered the AI Era
Neutral, unbiased, consistent and ethical by design - AI built to take the fourth seat at the table, working alongside human decision-makers.
Our Vision
Equip professionals with intelligent technology that brings greater consistency, efficiency, and effectiveness to every decision - closing coordination gaps, cutting through complexity, and delivering faster, fairer outcomes through AI that is fully transparent, accountable, and built to uphold the highest standards of procedural justice.
Mission & Team
Built by people who treat neutrality as an engineering requirement
We build trusted, neutral, unbiased, consistent and efficient dispute-resolution technology using responsible AI - and we are democratizing access to justice along the way.
OUR MISSION
Neutral by construction, not by promise
Procedural justice is paramount in ADR, ODR and any claims administration process. We design all of our technology and models so that neutrality and consistency are properties of the system, not assurances we ask you to take on faith.
OUR TEAM
Practitioners first, technologists second
Our team combines practicing dispute-resolution experience with two decades of applied AI and data-science work - built by people who have sat across the table from disputing parties, not just at a keyboard.
Provenance
Why "fourth party"
The term predates us. Dispute-resolution scholars describe the assistance of technology in resolving disputes as the "fourth party," alongside the two disputants and the traditional third-party neutral - a label that originated with Ethan Katsh and Janet Rifkin's 2001 book on online dispute resolution. We build the system designed to hold that seat well.
01
First party
One side of the dispute - the claimant, employee, customer, or counterparty bringing a grievance forward.
02
Second party
The other side of the dispute - the respondent, employer, vendor, or counterparty answering it.
03
Third party
The traditional neutral, hearing officer, claim administrator- helping the first two reach resolution.
04
Fourth party
Technology working alongside the third party - organizing information, applying it consistently, and removing the variance that erodes trust. This is the seat we build for.
