Justt

Justt builds an AI-native chargeback management platform for enterprise merchants. Its technology automates the post-transaction dispute lifecycle, including evidence collection, pre-chargeback alerts, dispute optimization, representment, reporting, and automated actions across payment service providers. Dynamic Arguments uses merchant, payment, transaction, shipping, identity, and other data to create a unique evidence-backed response for each dispute. The platform also evaluates expected returns on fighting a dispute and recommends whether merchants should accept or contest it.

The company serves more than 250 global enterprise merchants and has defended over $1 billion in disputes. Its platform supports merchants across SaaS, ecommerce, gaming, crypto, event ticketing, travel, and financial services, with integrations covering more than 40 payment platforms. Justt combines machine learning, continuous A/B testing, domain expertise, and payment-provider connectivity to improve dispute outcomes over time. Founded in 2020, Justt operates from Tel Aviv, London, and New York and emphasizes enterprise security, including SOC 2 Type II and ISO 27001-family certifications.
