Get in touch with our team.

Live chat from any page on stacksync.com gets you to a Stacksync engineer within minutes during business hours. For technical issues on a paid plan, the in-product help center routes directly to the support team. Email support@stacksync.com for non-urgent issues — typical response is within 4 business hours. Enterprise customers have a dedicated Slack channel with on-call coverage.

Standard support coverage is 24/5 (Monday-Friday) across US, EU, and APAC time zones. Enterprise plans include 24/7 coverage with named on-call engineers. Critical incidents (Severity 1: production data unavailability or data corruption) trigger pager rotation regardless of business hours on every plan tier. Response-time SLAs are documented in your service agreement.

For US-based partnerships, the New York team handles east-coast accounts and the SF team handles west-coast and APAC.
