2016

At Confluent, Hojjat created ksqlDB (KSQL), the first database purpose-built for stream processing. Working with customers revealed a clear gap: enterprises needed real-time data systems that were simpler, faster, and more accessible.

2021

Seeing the opportunity, Hojjat left Confluent to start building DeltaStream, a single, SQL-based platform powered by Apache Flink designed to simplify streaming analytics, cut costs, and unlock real-time insights. DeltaStream raised a $10M seed round led by NEA.

2024

The company raised its $15M Series A, led by NEA with participation from Galaxy Interactive and Sanabil, fueling rapid product development, team expansion, and partnerships across the data and AI ecosystem.

2025

DeltaStream announces general availability of DeltaStream Fusion, a unified analytics platform that combines streaming, real-time, and batch processing into a single, serverless solution. It can act as a real-time context engine for GenAI applications and agents by directly serving fresh, up-to-the-second data.
