Halcyon Data

Halcyon Data runs the warehouse and streaming layer for consumer subscription businesses that have outgrown a spreadsheet but do not want to hire a data platform team. We ingest events, model them into something analysts can trust, and answer questions about churn and lifetime value that used to take a quarter.

Correctness matters more than throughput here. A pipeline that is fast and quietly wrong costs a customer a board meeting, so we invest heavily in lineage, replay and the unglamorous work of handling late and duplicated records.

We are headquartered in Manhattan with engineering in Seattle and an APAC team in Sydney that owns follow-the-sun on-call.
