Company profile
researched Aug 2026DiffusionData develops Diffusion, a real-time data platform that sits between backend data sources and client applications, acting as a real-time gateway. The server ingests data from Kafka, Confluent, REST APIs, MQTT/IoT, databases, change data capture (SQL/Mongo), AMQP and Redis, transforms and optimises it in flight, and distributes it over WebSockets to web, mobile, desktop, Excel, IoT, backend, system and AI applications. Core architecture components include a data gateway for protocol translation and connection pooling, a hierarchical topic tree, a transform engine for low-code enrichment, filtering and aggregation, a security layer providing authentication, topic-level RBAC authorisation and TLS 1.3 encryption, a WebSocket gateway for routing, queuing and conflation, and a patented delta-streaming protocol that transmits only changed bytes.
The platform supports three messaging modes — publish/subscribe fan-out, request-response messaging, and fetch for point-in-time snapshots — plus in-memory caching and a latest-value cache that delivers current state to new subscribers before delta streaming begins. It also provides server-side filtering, per-session buffering and backpressure management with automatic throttling and auto-disconnect policies, session replication and sticky-session load balancing, and declarative conflation and topic-view policies for heterogeneous mobile, web and IoT clients. SDKs are offered for JavaScript/TypeScript, Java (JDK 17+), .NET, Python 3.8+, iOS (Swift), Android (Kotlin/Java) and C, with connectivity via WebSockets, HTTP streaming or MQTT.
Diffusion is deployed as a managed cloud service (Diffusion Cloud, with global edge points of presence), on-premise, in hybrid cloud/on-premise clusters, on Kubernetes via Helm charts, or through one-click deployment on AWS and GCP marketplaces, with consistent API behaviour across models. Documented use cases span market data feeds, live betting odds, notifications, live charts, environmental and GPS fleet telemetry, and multiplayer systems.
Business model
DiffusionData licenses and hosts its Diffusion platform for enterprises, offered as a managed cloud SaaS or as software deployed on-premise, in hybrid configurations, on Kubernetes, or via AWS and GCP marketplaces. Prospects enter through a free trial requiring no credit card, published pricing, or contact with a sales team, and paid support and services are offered alongside the product.
Commercial software and subscription cloud service, with free trials converting to paid usage of Diffusion Cloud or on-premise deployments; support and services are offered as a separate published offering.
Traction
Published customer results include Aposta Ganha reporting an 80%+ performance improvement after moving to Diffusion Cloud, Brenock deploying in one week and scaling from one ship to hundreds of vessels, Signal Centre reporting 4-6 months of development time saved, elimination of weekly downtime and 5x growth in its major client base, and an unnamed customer reducing bandwidth from 16TB to 2.5TB per month (about 85%) for roughly $1,200 per month or $14,400 per year in savings. A production Diffusion-Kafka integration is cited at 14 billion messages per month. A third-party profile lists roughly 7.6K monthly website visits.
Latest developments
In February 2026 DiffusionData announced it had won "Best Price Sharing & Publishing Solution" at the TradeTech Europe Awards 2026. Recent product additions include the Diffusion MCP Server for connecting AI agents and large language models to real-time data streams, direct integration with Confluent Platform and Apache Kafka, and AI-assisted management and built-in monitoring features.

Market position
DiffusionData describes itself as a pioneer and leader in real-time data streaming and event data solutions; a third-party profile characterises it as a market-leading real-time data streaming and messaging platform provider. In February 2026 it won "Best Price Sharing & Publishing Solution" at the TradeTech Europe Awards 2026.
The company positions Diffusion against building real-time middleware in-house and against cloud-only competitors, emphasising patented delta streaming for bandwidth and cloud-egress reduction, server-side filtering rather than client-side filtering of a pub/sub firehose, built-in backpressure and conflation to prevent slow clients from destabilising servers, native Kafka-to-WebSocket adapters that remove the need for custom microservices, and identical APIs whether run on-premise or in the cloud for regulated deployments.
Technology
Diffusion is a Pub/Sub server optimised for WebSocket delivery. Its patented delta-streaming protocol computes and transmits only changed bytes, including on binary data, reducing payload by up to 90%. Other technical elements include a hierarchical topic tree supporting millions of topics and wildcard subscriptions, strict per-topic message ordering with built-in caching and cluster-synchronised state, intelligent conflation, per-session queues and backpressure isolation, active-active clustering with automatic failover, multi-region replication, and linear horizontal scaling. Adapters cover Confluent/Apache Kafka (with Schema Registry support for Avro, Protobuf and JSON Schema, consumer group management, offset management and topic-to-topic mapping), REST, MQTT, CDC, Redis, AMQP and Microsoft Excel (RTD functions with bidirectional updates). A Diffusion MCP Server implements the Model Context Protocol to connect AI agents and large language models to real-time data streams with permissioned topic access.
Go-to-market
Self-service free trials of Diffusion Cloud and on-premise editions, a developers hub with documentation, quick starts, tutorials and GitHub examples, and a direct sales motion offering demos and expert consultations. Marketing content includes customer success stories, datasheets, white papers targeting retail, insurance, airlines and retail banking, tech talks, webinars and a blog. Cloud marketplace listings on AWS and GCP provide an additional distribution channel.
Enterprises building mission-critical real-time applications, including financial services, transportation, energy, retail, healthcare, eGaming/iGaming and IoT companies, with named customers including Betsson, Consorsbank, Signal Centre, Oddschecker, Aposta Ganha, Baker Technology and Brenock. Buyers are addressed in two segments: engineers/architects and executives/product leaders.
