Top BI & Big Data Consulting & SI Companies
Finance closes the month from spreadsheets, sales and operations report different revenue numbers, and nobody trusts the dashboards. BI and big data consulting and systems integration firms fix the plumbing behind that: they design a data warehouse or lakehouse on Snowflake, Databricks, BigQuery or Azure Synapse, build pipelines that pull data from ERP, CRM and product systems, model it into agreed metrics, and deliver reporting in Power BI, Tableau or Looker. Companies hire them for a first warehouse, a migration off on-premise SQL Server or Hadoop, or a governance program after a failed self-service rollout.
Shortlist firms by platform partnership, past work with your source systems, and how they hand over data ownership.
