€150 per seat, incl. VAT
For Bulgarian companies that need a VAT invoice and pay by bank transfer. Limited corporate allocation, no auto-renewals, no extensions. Once the corporate allocation sells out, the door closes on this tier and the remaining seats stay on the individual track until the 600-seat room cap.
- Bank transfer only. We issue the official invoice after the payment lands on our account.
- Limited corporate seats. Once the corporate batch is gone, this tier closes. Last year it sold out before September.
- Bulk-friendly. Whether you need two seats or twenty, one email is all it takes. We hold the seats for 5 business days while you process the payment.
- 600-seat room cap. Every ticket shares the same room. When the 600 fill up, registration shuts everywhere.

Why come
Three good reasons
The room is a mix: Kubernetes maintainers, platform engineers running clusters at scale, SREs, security folks, and the CTOs that pay for it all.
See what production looks like
Engineers from Bulgaria and beyond walk through how they actually run clusters: what broke, what they tried, what stuck.
Meet the rest of the room
Long breaks on purpose. Bring a question, leave with a name and a Slack handle from someone who has solved it.
