Ampersand is the native integration infrastructure for AI agents — real-time, bi-directional integrations that read from and write to your customer's systems. Fivetran moves data from SaaS apps into your data warehouse for analytics. They solve different problems — here's how to tell which one you actually need.
Fivetran is best-in-class at what it does: landing SaaS and database data in your warehouse for analytics. But a customer-facing product integration has completely different requirements — bi-directional writes, per-customer credentials, real-time sync, embeddable UI, and custom object support. These aren't gaps in Fivetran; they're out of scope. If you need any of them, you need a product-integration platform like Ampersand, not an ETL tool.
How the two platforms stack up across the dimensions that matter most for product integrations.
| Dimension | Ampersand | Fivetran |
|---|---|---|
| Category | Product integration platform Customer-facing | Warehouse ETL for analytics Different category |
| Primary User | Product engineering teams | Data engineering & analytics teams |
| Destination | Your application | Your data warehouse (Snowflake, BigQuery, etc.) |
| Sync Direction | Bi-directional with conflict resolution Reads + writes | One-way: source → warehouse Read only |
| Data Freshness | Sub-second webhooks (event-driven) Real-time | 5 min – 24 hours Batch ETL |
| Custom Objects | Full native support, all tiers | Supported for Salesforce/HubSpot ingestion; no write-back |
| Per-Customer Field Mapping | Built-in with embeddable UI Included | Not applicable — one connection per data source Out of scope |
| Multi-Tenant Auth | Built for many customer connections Multi-tenant | Built for one company's data pipeline Single-tenant |
| Embeddable UI | White-labeled React components for auth, field mapping, sync settings | None — no customer-facing components |
| Credential Ownership | You own & export OAuth tokens | Stored for analytics pipelines |
| AI / Agent Support | Open-source AI SDK + MCP server Agentic-ready | No native agent tooling |
| Compliance | SOC 2 Type II, GDPR, ISO 27001 | SOC 2 Type II, HIPAA, GDPR, ISO 27001 |
| Pricing Entry | Free tier → $999/mo (usage-based) | Free 500k MAR → $500+/mo MAR-based Volume-priced |
| Best For | Product integrations inside your SaaS app | Analytics pipelines into your warehouse |
The advantages that matter when your integration ships inside your product, not inside your warehouse.
Ampersand reads from and writes to your customer's systems. Create tasks in their CRM, update opportunities, post notes, attach files — from inside your product. Fivetran is one-way: it pulls data into your warehouse for analysis, with no write-back path.
Ampersand's event-driven architecture delivers webhook notifications in under one second. 11x cut their AI phone agent's CRM response time from 60 seconds to 5. Fivetran's sync cadence is 5 minutes at the fastest tier and typically longer — a deliberate batch-ETL design, not suitable for in-product UX.
Ampersand is built for SaaS products with many customers. Each customer connects their own account with their own OAuth tokens, their own field mappings, and their own sync settings. Fivetran is built to ingest your own company's data into your own warehouse — the single-tenant model doesn't map onto customer-facing product integrations.
Ampersand ships white-labeled React components for auth, field mapping, and sync settings. Your customer configures their own integration inside your app. Fivetran has no customer-facing UI — it's configured by your data team in Fivetran's dashboard.
Ampersand integrations live in amp.yaml files in your Git repo and ship through your CI/CD pipeline. Fivetran connectors are configured in Fivetran's web dashboard — the right model for data engineering, the wrong model for product integrations that need to version alongside your application code.
Ampersand's open-source AI SDK exposes integrations as tools that LLMs can invoke. The Docs MCP lets Claude Code and Cursor spin up integrations in minutes. Fivetran has no agent primitives — again, because it's an ETL pipeline, not an application-layer integration platform.
Fivetran charges by Monthly Active Rows ingested. Ampersand charges by integration actions. They measure different things.
"Using Ampersand, we cut Julian's response time from 60 seconds to 5."
"We chose Ampersand because we want to build an integration that we don't need to rebuild, and we want to meaningfully accelerate our upmarket journey."
"Ampersand is the first developer platform that gets it right."
"Ampersand is core to how we grow."
"Ampersand is helping Square connect to more upmarket Sellers, driving strong revenue growth."
We believe in being honest. These tools solve different problems — most teams will eventually want both.
Ampersand is purpose-built for customer-facing product integrations. Sub-second webhooks, bi-directional writes, embeddable UI — all versioned in your Git repo.
