Cards shipped, but never activated
Every unactivated card is lost interchange and a colder customer. Manual outreach can't keep pace with global issuance volume.

The card operations challenge
Global cardholders don't wait for a 9-to-5 call center.
KAST cardholders move money across timezones, currencies and merchants every minute. Helios turns activation, disputes and card servicing into instant conversations — at the scale stablecoin banking and global card programs demand.
Disputes pile up in long queues
Cardholders wait hours to report unrecognized charges. By the time intake completes, the chargeback window is already shrinking.
Support teams can't cover every timezone
Hiring native speakers in 170+ countries is impossible. Off-hours tickets stall, NPS drops, and cardholders churn to the next neobank.
Capabilities
You don't need a bigger contact center. You need always-on cardholder ops.
Use Helios to activate, support and resolve issues for every KAST cardholder — consistently, in their language, at any hour.
Capability 01
Instant card activation
The agent calls cardholders the moment their Visa card is delivered, verifies identity and walks them through PIN setup and first-spend.
- Outbound activation within minutes of card delivery
- Identity verification aligned to your KYC stack
- Guided PIN setup, app linking and first-spend nudge
Capability 02
Structured dispute intake
The agent collects every field required for chargebacks — merchant, amount, date, attempts to contact — and opens the case in your back office automatically.
- Reason-code-aware questioning by Visa rules
- Provisional credit decisioning on the call
- Case opened in your ops tool with full transcript
Capability 03
Global, multilingual coverage
Native-sounding conversations in the cardholder's language, available 24/7 across every market where KAST ships cards.
