What ScaleOut Software does

ScaleOut Software is a privately held in-memory computing platform vendor founded in 2003 by Dr. William L. Bain and headquartered in Bellevue, Washington. The company develops a suite of distributed in-memory data grid, data-parallel computing, streaming analytics, and digital twin products — including ScaleOut StateServer, Active Caching, GeoServer, Digital Twins, StateServer Pro, In-Memory Database (a Redis-compatible clustered database), and StreamServer — built on a patented quorum-based consistency algorithm that delivers strong consistency, linear scalability, and high availability across Linux and Windows environments. The products support Java and C#/.NET APIs and are deployed on-premises or via AWS and Azure marketplaces.

The platform serves enterprise customers across verticals such as financial services, telecommunications, healthcare, retail/e-commerce, media, airlines, and education, addressing use cases including session management, real-time risk analysis, fraud detection, digital twin simulation, IoT telemetry processing, and operational intelligence on fast-changing live data. Named deployments include Delta, AT&T, T-Mobile, Citi, ING, Humana, Staples, Honda, Adidas, GoDaddy, and Time Warner Cable, with the firm claiming hundreds of customers and more than 100 mission-critical installations handling tens of millions of data grid operations daily.

ScaleOut generates revenue through subscription and perpetual software licenses, tiered annual support plans (Basic, Standard, Gold, Platinum), and cloud marketplace transactions on AWS and Azure. Distribution combines a 30-day self-service free trial with direct enterprise field sales and quote-based multi-year contracts. The company has remained founder-led and self-funded, with no disclosed institutional venture funding, and has progressively expanded its platform over two decades via organic product development, cloud marketplace listings, and integrations with Kafka, Azure IoT Hub, AWS SQS, SQL Server, DynamoDB, and Cosmos DB, culminating in a 2025 OpenAI integration for natural language data access.

Core offering

ScaleOut Software develops and licenses an in-memory computing platform (the ScaleOut Product Suite) that combines distributed caching, data-parallel compute, and stateful streaming analytics to deliver operational intelligence on fast-changing data. The suite includes ScaleOut StateServer, StateServer Pro, GeoServer, Digital Twins V5, StreamServer, and In-Memory Database, deployed on-premises or in AWS/Azure with annual subscription or perpetual licensing and tiered support plans.

Product overview

ScaleOut Software offers a comprehensive suite of in-memory computing products for operational intelligence. The ScaleOut Product Suite (v6) includes five core products: ScaleOut StateServer (in-memory data grid with Active Caching), ScaleOut GeoServer (multi-site data replication for disaster recovery and global data access), ScaleOut Digital Twins V5 (streaming analytics and simulation using digital twin models), ScaleOut StateServer Pro (in-memory data grid with integrated data-parallel computing for operational intelligence), ScaleOut In-Memory Database (Redis Enterprise clustering with automatic management), and ScaleOut StreamServer (stateful stream processing with digital twin support). These products share a common clustering architecture built on patented technology for strong consistency, high availability, and linear scalability. They support both Linux and Windows platforms with Java and C#/.NET APIs. The suite is deployable on-premises or in public clouds including AWS and Azure. Optional add-ons include the ScaleOut Management Pack for monitoring and management, Remote Client for distributed access, and Archer IRM integration for Archer risk management customers.

Direct peers

• Hazelcast: Hazelcast provides an in-memory data grid (Hazelcast IMDG) and streaming platform (Hazelcast Viridian/Velocity) directly competing with ScaleOut's StateServer, StreamServer, and Digital Twins. Both target operational intelligence, distributed caching, and real-time analytics on live data.
• Redis (Redis Enterprise): Redis Enterprise offers a commercial in-memory database and caching platform built on open-source Redis, directly competing with ScaleOut's In-Memory Database and StateServer. ScaleOut's differentiation is multi-threaded execution and automatic clustering versus Redis Enterprise's sharding.
• GridGain Systems: GridGain offers an in-memory computing platform (built on Apache Ignite) for distributed caching, real-time analytics, and high-performance transactions. It is a direct competitor to ScaleOut's in-memory data grid products and shared Ignite lineage.
• Apache Ignite: Apache Ignite is an open-source distributed in-memory data fabric supporting compute and caching, serving as both a lower-cost alternative and a developer mindshare competitor to ScaleOut's IMDG/PaaS positioning.

Broad incumbents

• Amazon ElastiCache: AWS ElastiCache is a managed in-memory caching service (Redis and Memcached) bundled into AWS. It is a broad incumbent competing for the same workload budgets as ScaleOut, typically favored by AWS-native customers.
• Microsoft Azure Cache for Redis: Azure's managed Redis service is a broad incumbent offering that overlaps with ScaleOut's caching and in-memory database offerings. While ScaleOut is co-sold on Azure Marketplace, the managed service is often the default enterprise choice.
• Oracle Coherence: Oracle Coherence is an enterprise-grade in-memory data grid with deep Java integration. It is a broad incumbent in the same IMDG category as ScaleOut StateServer, with established enterprise customers but a heavier footprint.
• Pivotal/VMware Tanzu GemFire: VMware Tanzu GemFire is an enterprise in-memory data grid that competes directly with ScaleOut's StateServer across scale-out caching, consistent replicated data, and high-throughput operational workloads.
• Couchbase: Couchbase is a distributed NoSQL cloud database with built-in memory-first caching and query capabilities. It competes for similar operational intelligence and customer-facing workloads where ScaleOut is positioned.

Emerging players

• Aerospike: Aerospike is a real-time NoSQL database with in-memory and flash-optimized storage targeting sub-millisecond latency workloads. It competes with ScaleOut in applications like ad-tech, fraud detection, and real-time recommendations.
