The right combination of tools depends on your specific needs and existing infrastructure. For marketing attribution and ad optimization, Cometly provides the specialized capabilities you need to understand what's driving revenue and optimize accordingly.
For enterprise data warehousing, choose Snowflake if you want maximum flexibility and data sharing capabilities, or BigQuery if you're heavily invested in Google's marketing ecosystem. Redshift makes sense when you're already using AWS services extensively.
Visualization needs? Tableau remains the gold standard for user-friendly, powerful dashboards. Looker offers stronger governance if metric consistency across teams is critical.
Building real-time marketing systems requires event streaming. Combine Kafka for data movement with Spark for processing when you need to react to customer behavior in real-time.
For most marketing teams, the winning stack follows a clear pattern: a data warehouse (Snowflake or BigQuery) for centralized storage, an attribution tool (Cometly) for marketing-specific insights, a data integration platform (Fivetran or Segment) to move data efficiently, and a visualization layer (Tableau or Looker) for analysis.
Start with your biggest pain point. If you can't track attribution accurately, begin with Cometly. If data is scattered across platforms, start with a warehouse and integration tool. If insights aren't reaching decision-makers, prioritize visualization.
The tools covered here represent the current state of big data for marketing in 2026. They're mature, proven, and actively maintained. Choose based on your team's skills, existing infrastructure, and specific analytical needs rather than chasing the newest technology.
