Embedded iPaaS vs Universal APIs

This split in spend is really a sign that integrations are breaking into two separate software categories, not one. ETL and reverse ETL tools move large volumes of company data into and out of a warehouse for analytics, marketing, and sales ops. Embedded iPaaS sits inside a SaaS product so that its own users can connect apps, map fields, and run workflows without the vendor hard coding every edge case.

• The buyer and workflow are different. Fivetran loads data from apps and databases into Snowflake, BigQuery, or Redshift. Census sends modeled warehouse data back into tools like Salesforce or Braze. Those products are usually owned by data, marketing, or ops teams, not by the product team shipping customer facing integrations.

• Embedded iPaaS solves a different job. Alloy is aimed at SaaS companies that need integrations to appear native inside their own product. The customer can expose a connect flow, let users authenticate, map custom CRM fields, and configure logic. That is much closer to product infrastructure than to warehouse plumbing.

• The market education point matters because adjacent categories often get understood together before they separate. Census described reverse ETL in its early days as the return path from the warehouse, and noted that competitors help define the category. Alloy is making the same kind of argument, that moving data for internal teams is different from powering configurable integrations for end users.

Going forward, the line should get clearer as every SaaS product is expected to ship integrations by default, while every data team is expected to centralize and activate warehouse data. That creates room for both stacks to grow side by side, with universal APIs covering the simple read and write cases, and embedded iPaaS taking over once customers need deeper configuration.
