What Justt does
Justt is an Israel-based, AI-native chargeback automation platform that helps online merchants prevent, dispute, and optimize chargebacks across the full pre-chargeback and post-chargeback lifecycle. The company serves a diversified merchant base of 250+ enterprise customers and approximately 80,000 SMBs across SaaS, ecommerce, gaming, crypto, travel, event ticketing, financial services, and franchise verticals. Its core product combines an AI-driven Dynamic Arguments engine that generates unique representments per dispute (drawing on 500+ data points across 50+ PSP integrations and third-party sources), a Dispute Optimization feature that uses predictive ML to recommend fight-vs-accept decisions based on net dollar recovery, pre-chargeback alerts via Verifi CDRN/Ethoca, an Insights analytics dashboard with win-rate forecasting, and a live production deployment of NVIDIA's Nemotron Parse vision-language model that reduced document extraction errors by 25% versus legacy OCR.
The platform is delivered as a managed service with success-based pricing: merchants pay only when chargeback funds are recovered and can no longer be clawed back, aligning Justt's incentives with merchant outcomes. Distribution combines direct enterprise sales (offices in Tel Aviv, New York, London, and Tampa), a self-serve Shopify App Store offering (Justt Lite), and a franchise-vertical partnership channel. The company has raised $100 million across rounds in 2021 ($70 million) and December 2024 ($30 million Series C led by Zeev Ventures with Oak HC/FT and F2 Venture Capital), and in 2026 became the first chargeback/dispute management company named to the Forbes Fintech 50. The leadership team is led by co-founders Ofir Tahor (CEO) and Roenen Ben-Ami (CRO, formerly head of chargeback and merchant risk at Simplex), with co-founder Roenen Ben-Ami bringing deep domain expertise from payments.
Justt's underlying technology is differentiated by a continuous A/B testing layer across reason codes, issuers, and PSPs, plus deep integrations with Tier 1 PSPs (Stripe, Adyen, Braintree, PayPal, Chase, Checkout.com, Nuvei, Worldpay, Shopify) and card-network alert providers. Security and compliance posture is enterprise-grade (SOC 2 Type 2, ISO 27001/27017/27018/27701, GDPR, CCPA), supporting sales into regulated enterprise merchants.

Justt competitors and assessment
Company assessmentDirect peers
- Chargeflow: AI-driven chargeback automation platform for ecommerce and SaaS merchants. Competes head-to-head with Justt on automated representment, dispute analytics and pre-chargeback alerts, with overlapping PSP integrations and target verticals.
- Chargebacks911: Long-standing chargeback management and dispute resolution provider serving enterprise merchants. Directly comparable service offering (representment, alerts, analytics) and is listed both as a competitor (Justt comparison pages) and as a partner integration.
- Midigator: Chargeback management and prevention SaaS for subscription and ecommerce merchants. Comparable core product (automated representments, alerts, analytics) and similar target segments, making it a direct head-to-head competitor to Justt.
- Chargeback Gurus: End-to-end chargeback and dispute management services with technology and human-assisted workflows. Overlaps with Justt on automated representment and analytics for enterprise merchants in ecommerce, SaaS and travel.
Broad incumbents
- Kount (Equifax): Established fraud and dispute-prevention platform owned by Equifax. Overlaps with Justt on chargeback prevention and decisioning but operates as a broader fraud/risk suite rather than a chargeback-specialist.
- Ethoca (Mastercard): Mastercard-owned pre-chargeback alert and merchant collaboration network. Justt integrates Ethoca alerts, but at scale Mastercard could bundle dispute automation into its network — making Ethoca both a partner and an incumbent competitive threat.
- Verifi (Visa): Visa-owned provider of CDRN (Cardholder Dispute Resolution Network) and Rapid Dispute Resolution. Operates upstream of Justt by issuing pre-chargeback alerts — a partner today but also a potential disintermediator of dispute automation.
Emerging players
- Ravelin: Fraud detection and chargeback prevention platform focused on ecommerce and subscription merchants. Comparable target verticals (SaaS/subscription, ecommerce) and overlapping value proposition around reducing chargebacks via better decisioning.
- Sift: AI-based digital trust and fraud prevention platform. Not a direct chargeback specialist, but competes for the same fraud/dispute budget at large merchants and increasingly offers dispute-related workflow tooling.
- Riskified: Public fraud-management platform that has expanded into chargeback guarantee and dispute handling for ecommerce merchants. Adjacent category with partial overlap on chargeback-related decisioning, more established with large enterprise retailers.
