Justt

Justt operates on a success-based fee model. Merchants are charged only after a chargeback lifecycle fully completes and funds are returned, making its revenue contingent on dollar recovery rather than a flat software subscription.

Rather than using static templates, Justt's AI generates dynamic arguments tailored per dispute based on issuer, cardholder data, and merchant-specific learnings. The system connects to over 500 data points and runs granular A/B tests to continuously tune the evidence it produces for representment.

Justt employs domain experts who monitor scheme rule changes and adapt the company's AI model layer directly. The Chief Risk Officer, Roenen Ben-Ami, has publicly authored analyses on new programs like Mastercard SMMP 2026 and the tighter VAMP thresholds that took effect in March 2026.

Justt is a platform with a combined model. It automates the end-to-end chargeback management workflow, but it retains a customer success team that can manually intervene in disputes and adjust strategies, letting merchants choose between full autopilot or a monitored process.

Justt offers integrations with multiple payment service providers to standardize chargeback data into a single unified interface. Details of specific PSP integrations are available at the application layer, but the platform is designed to consolidate data across a merchant's processor relationships.

Ofir Tahor is Co-Founder and CEO, and Roenen Ben-Ami is Co-Founder and Chief Risk Officer. The firm's C-suite also includes a Chief Product Officer (Orly Amrany) and a Chief Technology Officer (Shahar Tal).

Yes. The platform offers pre-dispute alerts to prevent chargebacks through partnerships with Visa and Mastercard, and includes an optimization engine that predicts dispute-level ROI to recommend whether to fight or accept a chargeback. It also provides predictive dashboard insights to inform a merchant's broader payment risk strategy.
