Real-time ETL: the streaming pipeline you don't hate to operate
Fivetran is for batch. The product that does streaming CDC from Postgres / MySQL to a warehouse with sub-minute latency, without a PhD to operate, wins the operational analytics market.
Why now
Debezium + Kafka is technically correct and operationally painful. ClickHouse + Materialize made streaming queryable. The remaining work is the operator-facing UI that turns the whole stack into a five-minute setup.
The idea you could build today
One-command install. Connect to source DB via CDC. Stream to ClickHouse / BigQuery / Snowflake. Transforms in SQL. UI that shows lag, throughput, and per-table state. Per-GB pricing under Fivetran.
Build stack
- ·Debezium or homegrown CDC
- ·ClickHouse or Snowpipe for the sink
- ·Rust or Go for the streaming engine
- ·Next.js for the operator UI

The seed-round pattern hiding in the trendline
Streaming-ETL OSS repos with velocity in the "single-binary" or "managed-control-plane" milestones are the seed-stage tells.
Frequently asked
What about Fivetran / Airbyte?+
Batch-shaped, expensive. The CDC-streaming, ops-friendly version is the wedge.
