Company profile
researched Aug 2026Aerospike is the company behind the Aerospike Database, a distributed, real-time NoSQL key-value database management system written in C and running on Linux. The database is designed for applications that cannot tolerate downtime and that require high read and write throughput with predictable, sub-millisecond response times. It supports key-value, JSON document, graph and vector-search data models, is optimized for NVMe SSDs holding datasets from gigabytes to petabytes, and can also be deployed as a fully in-memory cache database.
The company positions the product as a real-time database for predictive, generative and agentic AI workloads: serving hundreds of signals per inference at bounded P99 latency, holding live user context such as preferences, activities and vectors for generative applications, and storing intermediate agent outputs as micro-datasets so agents can chain reasoning and resume workflows. Deployment options span local development with Docker through two-node clusters to globally distributed replicas using cross-datacenter replication (XDR), with connectors for Spark and Kafka, streaming ingestion and change-data-capture. Aerospike also offers Voyager, a visual workspace for querying, troubleshooting and visualizing data that can connect coding agents such as Claude and Cursor to a cluster, and Aerospike Academy for hands-on training.
The software was initially used mainly in advertising as a server-side cookie store, forming core user-data storage for adMarketplace, BlueKai, Tapad, The Trade Desk, Sony's So-net and eXelate, and later expanded into payments, gaming, cyber-security and e-commerce.
Founding story
Citrusleaf was founded in Mountain View, California in 2009 by Gian-Paolo Musumeci, CTO Brian Bulkowski and vice president of engineering and operations Srini V. Srinivasan. According to company materials, it was founded to push the limits of modern processors, storage technologies and distributed systems, with the goal of making scaling accessible to developers outside large internet companies that could build their own infrastructure.
Business model
Aerospike develops and commercializes the Aerospike database, which is available as open-source software (server under AGPL 3.0, client SDKs under Apache 2.0) alongside a commercial Enterprise Edition. Customers can consume the product in three ways: Aerospike Cloud, a fully managed, self-service database-as-a-service peered to the customer's cloud VPC; a Managed Service in which Aerospike SREs operate the database inside the customer's own cloud environment; and self-managed deployment on Kubernetes, containers, VMs or bare metal. A startup program has offered qualifying companies free access to the Enterprise Edition together with application design consulting.
Revenue derives from commercial licensing of the Aerospike Enterprise Edition and from cloud and managed-service offerings, alongside a freely available open-source edition.
Traction
Reference deployments cited by the company include Criteo, which delivers a trillion ads per day, consolidated 3,200 servers to 800 and sustains 250 million transactions per second under a 50ms end-to-end SLA; Wayfair, which runs 1 million transactions per second for predictive AI recommendations at sub-millisecond P99.9 latency on seven nodes; and LexisNexis, which runs a 1.3-petabyte identity network and reports $3.3 million in savings over three years. Wikipedia lists 101-200 employees as of 2020. The company appeared on the Inc. 5000 fastest-growing companies list in both 2023 and 2024.

Market position
Aerospike is a private NoSQL database vendor competing with distributed and in-memory data stores including Cassandra, HBase, MongoDB, Redis and Couchbase, and with relational systems such as PostgreSQL in latency- and cost-sensitive workloads. It is used by large-scale enterprises across advertising, payments, retail, media measurement, gaming and financial fraud detection, with named users including Adobe, PayPal, Barclays, Nielsen, LexisNexis Risk Solutions, The Trade Desk, Criteo, Wayfair, Dream11, Playtika and Rakuten. Industry recognition includes appearances on the Inc. 5000 list in 2023 and 2024, CRN's Edge Computing 100, the Big Data 100 and DBTA's list of companies that matter most in data.
Aerospike's principal technical claim is its patented Hybrid Memory Architecture, which keeps indexes in RAM while storing data on SSD, NVMe or persistent memory, aiming to deliver memory-like latency at the cost and durability of flash and removing the need for a separate caching tier. The company emphasizes deterministic, tightly bounded tail latency under sustained load, and configurable consistency modes ranging from high availability with no replica divergence to strong consistency with ACID-compliant transactions even at replication factor 2. Cited customer outcomes include Criteo consolidating 3,200 servers to 800 while sustaining 250 million transactions per second under a 50ms end-to-end SLA, Wayfair running 1 million TPS with sub-millisecond P99.9 latency on seven nodes, and LexisNexis operating a 1.3-petabyte identity network with $3.3 million of savings over three years. A customer at Adobe described evaluating Aerospike against Cassandra and HBase and selecting it on 95th-percentile latency and sustained throughput; PayPal cited hybrid memory architecture as the reason for migrating from another in-memory database.
Technology
Aerospike Database is built on a shared-nothing architecture written in C and operates in three layers: a data-storage layer, a self-managed distribution layer and a cluster-aware client layer. Its hybrid memory architecture holds indexes entirely in RAM while persisting records to SSD, NVMe or persistent memory; reads use direct pointers from the primary index to the record position on disk and writes are batched into large block writes to reduce latency, avoiding a separate data cache. Features added across releases include geospatial queries and native list types, secondary indexes on lists, maps and geospatial data, durable deletes, IPv6, TLS, encryption at rest, LDAP and PKI authentication, all-flash namespaces, Kafka and JMS change-notification connectors, record-level compression, HyperLogLog types, HashiCorp Vault integration, Aerospike Expressions, multi-site clustering with strong consistency, and JSON document storage and partitioned secondary index queries in version 6.0. The current stable release documented is 8.0.0.7 (April 26, 2025).
Go-to-market
Aerospike combines open-source distribution and developer-led adoption with enterprise sales. Developers can start locally with Docker, official container images and interactive training through Aerospike Academy, while commercial engagement is via "talk to an expert" enterprise motion, managed services staffed by Aerospike SREs, and technical account managers, whose involvement Playtika described as central to its project. The company has also run partner and accelerator programs, including a startup offer distributed through Founders Space, and adtech partnerships with Adform, InMobi and Vizury.
Enterprises and high-scale internet companies running latency-critical, high-throughput workloads: advertising technology (real-time bidding platforms and data management platforms), payments and fraud detection, e-commerce and retail supply chain, gaming, media measurement, cyber-security and AI inference pipelines. Named customers and references include Adobe, PayPal, Barclays, Nielsen, LexisNexis Risk Solutions, Criteo, Wayfair, The Trade Desk, Dream11, Playtika, Rakuten Asia, AppNexus, BlueKai, Tapad and adMarketplace.

History
The company was founded in Mountain View, California in 2009 as Citrusleaf, began providing its database in 2010 and announced the product in 2011. In August 2012 it rebranded both company and software to Aerospike, a name taken from the aerospike rocket nozzle that maintains efficiency across a wide altitude range, and in the same month acquired AlchemyDB, a hybrid RDBMS/NoSQL datastore led by Russell Sullivan, integrating relational data-management functions; the acquisition was funded by New Enterprise Associates, Draper Associates, Columbus Nova Technology Partners and Alsop Louie Partners. On June 24, 2014 Aerospike open-sourced the database server under AGPL 3.0 and its client SDKs under Apache 2.0, and raised a $20 million Series C. It formed adtech partnerships with Adform, InMobi and Vizury in 2014, named former Salesforce.com executive John Dillon CEO in February 2015, and announced a $32 million round led by Triangle Peak Partners on November 18, 2019. Product milestones include strong consistency in version 4.0 (2018), refactored cross-datacenter replication and multi-site clustering in 5.0 (2020), JSON document storage and querying in 6.0 (2022), and release 8.0.0.7 in April 2025.
