Accel, Uncorrelated Ventures, and other investors led a $3.85 million funding round for data infrastructure startup S2.dev.
The startup was chosen in the Fall 2025 batch and had previously received support from Y Combinator. To date, the company has raised a total of $5.5 million.
According to a press release from S2.dev, the new funding will be used to support early enterprise clients, extend its managed cloud service to additional global regions, and speed up product development.
S2.dev, a serverless datastore for real-time, streaming data, was co-founded in 2024 by Shikhar Bhushan, Stephen Balogh, and Dwarak Govind Parthiban. It was created especially to support multiplayer, agent-based, and collaborative applications.
The platform provides developers with low-latency performance and object storage persistence through robust, auto-scaling streams that are accessible via REST.
The primary offering from S.dev is a serverless streaming database platform that lets programmers handle stateful data and fast-moving, real-time data publishing without worrying about infrastructure management. In order to generate on-demand streams for modeling domain data, the startup offers infinite streams that can be fenced, appended to, and pulled from.
S.dev claims that its product is centered on long-lasting streams and seeks to transform streams into a primitive form of cloud storage. These streams may consist of messages exchanged between several agents or token output in artificial intelligence (AI) applications.
The market is currently dominated by cloud services like Amazon Kinesis and tools like Apache Kafka, which businesses use to manage real-time data, such as clicks, payments, event tracking, and app notifications.
