First day 

Opening session

Roenen Ben-Ami, Co-founder and Chief Risk Officer of Justt

Join Roenen for a quick overview on how chargebacks fit into today’s payment operations

What I wish I knew about chargebacks - before leading payments at scale

Sarah Boehmer, Senior Director, Payment Processing & Fraud Strategy at Super.com; Moderator: Chen Naim, Enterprise Customer Success at Justt

In this session, Sarah Boehmer shares what it’s like to take on chargebacks, payment operations, and fraud strategy inside a fast-growing company that’s both an online travel agency and a subscription business. She’ll cover everything she learned along the way: the tradeoffs chargebacks create (from authorization rates to processor expansion), the unpublished truths payment professionals need to know, and the practical realities of setting chargeback strategy, securing executive buy-in, and partnering effectively with customer-facing teams.

Chargebacks in the real world

Maisa Breve, Customer Operations Manager at Vio; Karlynn Ferris, Customer Resolution Manager at Sunbit; Will Plummer, CEO of Trust My Group; Moderator: Dwayne Gefferie

Join chargeback and payments leaders as they discuss their real life challenges and achievements in managing chargebacks

Getting ready for change: dealing with Visa timeline and fee changes

Kimberly Singleton, Director of Product Management at Worldpay

With recent rule changes, accepting and defending chargebacks on time is becoming a crucial matter for merchants, who also need to ensure that they maximize their likelihood to win chargebacks. Solutions for this change include automation, as well as smart use of Verifi’s pre-dispute solutions like RDR and CDRN. We’ll take a look at what rule changes mean and point out how to adjust your operations to excel, even with higher fees and stringent deadlines.

Are you risk-loving or risk averse?

Robbie MacDiarmid, VP, Consulting at CMSPI

Merchants rely on an ever-growing number of partners in the payments supply chain to support their business and end goal of serving customers.
This session explores how chargebacks can reveal your organisation’s true appetite for risk: whether intentional or not. We’ll examine how different payment setups, partners and mitigation strategies reflect underlying risk preferences, uncovering whether your resultant payment profile signals extreme risk-aversion or a bold risk-taker in disguise.

Demystifying VAMP: what merchants need to know

Ami Patel, Vice President, Visa Risk Programs at Visa and Roenen Ben Ami, Chief Risk Officer and Co-founder of Justt

This session brings together experts from Visa and Justt to explain the changes presented by VAMP, which will replace VDMP and VFMP, reshaping how Visa monitors fraud and disputes globally. Tune in to understand what is really changing and how things have shaped up since VAMP was announced. Learn what changes you need to make and better understand what VAMP means for your business.

Second day

Winning the Chargeback Battle: Strategic Insights from Acquirers and Networks

Ludovic Houri, Managing Director, Head of Merchant Services EMEA/APAC at JP Morgan and Katie Steel, VP Security Solutions at Mastercard

This session will help merchants understand the current trends and challenges driving disputes, identify actions they can take now to reduce and manage chargebacks, and prepare for the future of commerce, including the impact of agentic commerce and AI-driven customer interactions.

Are chargebacks still the black sheep of payments, or are they finally evolving?

Brian Davis, Host of The House of Fraud; Barbara Redaelli, Fraud & Dispute Strategy Manager at Lastminute.com; Dave Gestaut, Principal Technical Program Manager at Microsoft; Moderator: Roenen Ben-Ami, Co-Founder and Chief Risk Officer of Justt

Chargebacks have long been seen as the odd one out in the payments ecosystem, full of complexity and therefore overlooked. Are these attitudes finally shifting? Three industry practitioners will try to answer this question: Brian Davis (The House of Fraud), Dave Gestaut (Microsoft), and Barbara Redaelli (Lastminute.com). They will reflect on the state of chargebacks since they began their careers and explore how chargeback management has evolved since, including automation, processes and the importance of revenue recovery.

Automation, optimization and setting up for success

Roenen Ben Ami, Co-founder and Chief Risk Officer of Justt and Orly Amrany, Chief Product Officer at Justt

In this session, Orly and Roenen will share recent industry developments and how they have impacted Justt’s product. We’ll be talking strategy, automation and showing off some cool features.

Getting ready for agentic (AI) payments - what you need to know

Shahar Tal, Chief Technology Officer at Justt; Jamie George, VP of Account Management and Partnerships at Ravelin; Ofir Tahor CEO and Co-founder of Justt

Amazon’s new “Buy for Me” beta feature lets shoppers outsource the entire checkout process on third-party sites to an in-app AI agent—no browser, no manual form-filling, just one click. This marks the rise of “agentic commerce,” where AI agents will automate price-shopping and will then carry out transactions on behalf of consumers. In this new world, bot traffic may now mean legitimate purchasing intent, and chargebacks may take a different turn. Imagine the friendly disputes emanating from forgotten orders, mistaken prompts (“I meant one, not ten!”), or agent glitches—all creating chargebacks in a completely different context. Join this session to explore the possibilities and to understand how you can prepare for them.
