Cardtonic explains V3 outage that disrupted gift card services

Cardtonic 's July 3, 2026 account of its V3 migration describes a growth investment that temporarily undermined the services it was meant to improve. The June 21 upgrade ran close to 18 hours of downtime against a planned three-hour window, with follow-on problems continuing over subsequent days. [S01] The company said its older architecture had become an obstacle to adding products and processing reliably at greater scale. Wallet synchronisation and data consistency problems emerged during migration. Funding, transactions and identity checks were affected, followed by issues across gift-card and other services. [S01] A gift-card business with more at stake Cardtonic buys unwanted gift cards from customers and sells cards for shopping and digital services. Its wider catalogue now includes virtual dollar cards, bill payments, eSIMs and gadgets. Those services create several reasons to return to the same app, but they also make the shared wallet and transaction history more consequential. [S02] The company has described its development as self-funded. In a September 2025 account, it said the founders started with personal savings and that virtual dollar cards had grown to represent more than half its revenue. Those are the company's historical disclosures, not independently verified 2026 financial results. They help explain why rebuilding the platform matters beyond its original gift-card offering. [S03] Corporate materials identify The Tonic Technologies as the business behind Cardtonic and Emmanuel Sohe as CEO. The incident statement itself is attributed to Cardtonic, not presented as a personal statement from Sohe. [S04] The economic logic of the upgrade The commercial rationale is understandable: a platform that can add services and handle more transactions has more opportunities to earn from an existing customer relationship.
