RisingWave is a distributed SQL streaming database that lets developers ingest, transform, and serve real-time data using familiar PostgreSQL-compatible SQL instead of specialized stream-processing frameworks. Founded in 2021 by former AWS Redshift engineer Yingjun Wu, the San Francisco company decouples compute from storage in a cloud-native architecture, offers incremental materialized views, and integrates natively with Apache Iceberg to power a streaming lakehouse. Its open-source engine and managed RisingWave Cloud target fraud detection, monitoring, real-time analytics, and increasingly the data infrastructure behind agentic AI.
Striim is a Palo Alto-based enterprise software company that builds a unified real-time data streaming and integration platform. Founded in 2012 by the team behind GoldenGate Software, Striim uses change data capture (CDC) to continuously ingest, process, and deliver high volumes of data with sub-second latency from databases, logs, and applications into cloud warehouses like Snowflake, Databricks, BigQuery, and Microsoft Fabric. Its platform powers real-time analytics, cloud migration, and AI-ready data pipelines for enterprises including UPS, American Airlines, Macy's, and Morrisons.
Artie is a San Francisco-based, fully managed real-time data streaming platform that uses change data capture (CDC) and log-based replication to move production data across databases, warehouses, search systems, and vector stores with sub-minute latency and zero pipeline maintenance. Founded in 2023 by Jacqueline Cheong and Robin Tang and backed by Y Combinator, Artie pitches streaming-first data movement as the default for AI-era systems, replacing brittle batch ETL and self-managed Kafka.

Jacqueline Cheong is the co-founder and CEO of Artie, a San Francisco data infrastructure company that streams changes from production databases into warehouses in real time using change data capture. A UC Berkeley applied math graduate who spent her early career as an equity analyst at Bank of America and a software investor at the hedge fund Balyasny, she switched sides of the table in 2023 to build the kind of company she used to underwrite, co-founding Artie with her husband and CTO Robin Tang. After going through Y Combinator's Summer 2023 batch, the pair grew Artie to a roster of enterprise customers including ClickUp, Substack, and Alloy processing more than 700 billion rows a year, and raised a $12 million Series A led by Standard Capital's Dalton Caldwell in January 2026, on top of a $3.3 million seed.
