Software Development Boston, Massachusetts 201–500 employees Founded 2017 Privately Held

Jellyfish sells analytics to engineering leaders on how R&D teams plan, deliver, and adopt AI. Its stack is unusually data-heavy, running Databricks, Spark, Delta Lake, ClickHouse, Snowflake and BigQuery alongside three orchestrators (Airflow, Prefect, Dagster), with dbt being adopted. Data roles lead an accelerating hiring mix, matching pain points around governance, inconsistent data models and maturing the Databricks platform.
