Data infrastructure startup S2.dev has raised $3.85 million (approximately Rs 32 crore) in a funding round led by Accel, with participation from Uncorrelated Ventures and other investors. The startup was previously backed by Y Combinator as part of its Fall 2025 batch and has raised a total of $5.5 million to date. The funding reflects growing investor conviction in infrastructure platforms enabling real-time, AI-native software systems.
Building serverless infrastructure for real-time streaming data
Founded in 2024 by Shikhar Bhushan, Stephen Balogh, and Dwarak Govind Parthiban, S2.dev provides a serverless datastore designed to manage real-time streaming data without requiring infrastructure management. Its platform enables developers to build collaborative, multiplayer, and agent-based applications using durable, auto-scaling streams accessible via REST. By combining object storage persistence with low-latency performance, the startup simplifies complex data infrastructure workflows.
Capital to support product development and global expansion
The fresh capital will be used to accelerate product development, expand its managed cloud service into additional global regions, and support early enterprise customer adoption. As AI systems increasingly depend on continuous data exchange between agents and applications, S2.dev aims to strengthen its infrastructure to support enterprise-grade reliability and scalability.
Challenging legacy real-time data infrastructure providers
S2.dev’s platform introduces durable streams as a cloud storage primitive, allowing developers to create unlimited streams on demand and scale seamlessly. The real-time data infrastructure market is currently dominated by legacy tools like Apache Kafka and cloud services such as Amazon Kinesis. S2.dev’s serverless approach positions it to reduce operational complexity while enabling developers to build scalable, AI-native applications more efficiently.
