What is DBT’s competition? I have to come up with three vendors for procurement to purchase DBT cloud.

You could probably consider a few: Databricks live tables with autoloader Datameer, SaaS offering but only for snowflake Coalesce, new company barely in the alpha stage Matillion, more than just the T layer, also does orchestration and ingestion. Others to include here are the likes of Informatica, Data Factory, Synapse, etc. LookML, data modeling layer, but in a visualization tool. Could argue Power BI also fits here with their data flows. Home baked, do it yourself, custom python and sql scripts using any orchestrator like dagster, airflow, prefect.
