About
Aerospike is a real-time distributed NoSQL database platform designed for mission-critical, low-latency applications. Founded in 2009 (originally as Citrusleaf) and headquartered in Mountain View, California, with offices in London, Bangalore, and Tel Aviv.
The database server is written in C to avoid garbage collection unpredictability, using a Hybrid Memory Architecture that stores indexes in DRAM and data on SSDs/NVMe. Customers include Adobe, PayPal, Snap, Sony Interactive Entertainment, and DBS Bank. Aerospike has raised approximately $171M, including a $109M Series E in 2024 led by Sumeru Equity Partners.
The database server is open source on GitHub. The engineering team works with C (core database), multi-threaded Flash I/O, and log-structured file systems optimized for modern storage hardware.
