Justt
Justt is an AI-powered chargeback automation platform for high-volume merchants, co-founded by Ofir Tahor and Roenen Ben-Ami. It builds technology to dispute chargebacks—primarily first-party misuse—using a data-driven system that customizes evidence per case rather than relying on rigid templates. The company reports integrating with over 500 data points to automate the dispute process, giving its models continuous feedback through granular A/B testing. The platform covers the full dispute lifecycle: it handles representment with tailored arguments, automates chargeback acceptance through configurable policies, and optimizes fight-vs-accept decisions by predicting expected ROI net of fees. Its real-time data enrichment layer pulls from third-party sources and merchant-provided input via API or CSV, while pre-dispute tools like Visa VAMP and Mastercard SMMP alerts help merchants prevent chargebacks. The company actively writes public analyses of card network policy updates, with CRO Roenen Ben-Ami authoring technical explainers on SMMP 2026 and VAMP tighter threshold changes. The firm is headquartered in the Azrieli Sarona Tower in Tel Aviv and operates on a success-fee model—merchants pay only when capital is returned. Its announced backers include a listed syndicate of unnamed institutional investors in partnership with a team whose public resumes combine product, payments risk, and people operations. Justt’s architecture is unusual in that it fuses an AI-native product with a human-in-the-loop domain expertise team that adapts the model layer in response to card network rule changes, making its risk operations subsidiary to a litigation-automation strategy rather than a standalone SaaS subscription product.

Frequently asked questions
How does Justt make money?
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.
What is Justt's technical approach to improving win rates?
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.
How does Justt handle card network rule changes?
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.
Is Justt a managed service or purely a software product?
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.
Which payment service providers does Justt integrate with?
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.
Who are the founding operators of Justt?
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).
Does Justt do anything besides chargeback representment?
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.
