SereneDB, a Berlin-based database startup, has raised $2.1 million in a pre-seed funding round led by Entourage and High-Tech Gründerfonds. The company is developing a dedicated real-time search and analytics database designed to address the limitations of legacy systems that struggle with rapidly changing, complex data.
Founded in 2025 by Alexander Malandin, Andrey Abramov, and Valery Mironov, the company is building an open-sourced distributed engine that unifies search and analytical processing under the PostgreSQL ecosystem. The technology enables real-time ingestion with accurate updates and deletions, aiming to deliver millisecond response times for complex analytical queries.
SereneDB’s approach seeks to eliminate the need for teams to combine disparate tools for indexing, caching, and dashboarding. By consolidating these functions into a single system, the company intends to reduce operational complexity, lower infrastructure costs, and empower both humans and AI agents to analyze live data more effectively.
The investment will support SereneDB’s continued open-source development strategy, which the company says is central to fostering community involvement and accelerating adoption. The goal is to set a new practical standard for modern analytics by providing trustworthy, real-time insights throughout the data lifecycle.
HTGF, one of Europe’s most active early-stage investors, and Entourage, an early-stage fund backed by prominent SaaS founders, both highlighted SereneDB’s potential to impact the next generation of analytical applications across the enterprise software landscape.
The company’s team previously helped build what it describes as the world’s fastest enterprise-grade C++ search library. This experience gives it a strong foundation for defining a new category of performance-focused analytics infrastructure.
SereneDB’s product and roadmap emphasize real-time processing, standardized SQL interfaces, and an open-source model intended to benefit the broader data community. The company says its unified system will enable businesses and AI systems to ask better questions using the freshest available data while reducing tooling redundancy.
The announcement follows SereneDB’s formal corporate establishment earlier this year and reflects growing investor interest in foundational technologies supporting AI-driven workloads and next-generation analytics.
