Verifi buys merchants time before a charge becomes a chargeback
A forgotten purchase can become an expensive argument. Verifi, the Visa-owned dispute specialist, gives merchants a chance to clarify the charge, refund it, or defend it before the paperwork takes over.
The Fraud Fighter That Learned to Say Yes
Ravelin began with a taxi app’s fraud problem and built a business around a counterintuitive promise: stop the thieves without turning good customers away. Worldpay bought the company in 2025 - but the more revealing story is how five engineers made restraint into a product.
Fikäfi
Fikäfi is a Singapore-registered payments company built for hotels. It sits between a hotel's booking system and its bank, sending time-bound payment links over email, SMS or WhatsApp, capturing cards before arrival, automating reminders, settling funds by SWIFT, and pushing wallet credit back to guests so they rebook direct instead of through an OTA. Card processing starts at 1.95% with no setup fee or monthly minimum. Co-founded by hospitality-technology veteran Andre Privateer alongside Imran Saeed, the company argues that the industry's real leak is not the guest who cancels but the booking that quietly dies at the payment step - what it calls the "shadow guest." In March 2026 the PMS vendor Elektraweb embedded Fikäfi's payment orchestration layer across a platform serving thousands of hotels.
Trustap
Trustap is an Irish fintech that provides escrow-style, milestone-based payment infrastructure for online marketplaces, ecommerce platforms and individuals. Acting as the merchant of record, it holds a buyer's funds until goods or services are confirmed as delivered, then releases them to the seller - reducing fraud, chargebacks and disputes for high-value and peer-to-peer transactions. Founded in Cork in 2017 by Conor Lyden after he was scammed buying football tickets, the company now works with 250+ partners across roughly 27 countries and is building Trustap Index, a product that makes marketplace listings machine-readable and transactable by AI shopping agents.
Sticky.io
Sticky.io is a San Francisco-based revenue optimization platform for high-volume subscription and ecommerce brands.

The platform supports roughly 72 million subscriptions and processes more than $12 billion in transactions annually, helping merchants reduce silent churn and recoup failed payments.
