Adaptive: bespoke trading systems and Aeron infrastructure

Adaptive builds trading technology for financial firms that want control over their application logic and product development. Its current structure combines an open-source Aeron foundation, licensed infrastructure components, an enterprise platform and domain accelerators. A purchase can therefore range from support for an existing engineering team to a substantial custom trading-system project. The September 2026 product explanation makes these layers explicit; the amount of software, engineering and operational responsibility supplied changes with the engagement.[1]

Hydra supplies foundations for single-dealer platforms, RFQ workflows, smart order routers, internalisation engines, OMSs, FIX gateways and trading interfaces. This is a development and operating toolkit: the product description identifies workflows that can be built on it, while the actual dealing model, connected markets and business rules are determined in the application project. Its advertised uptime and latency figures require deployment-specific engineering and contractual scope.[5]

Sequencer distributes a globally ordered message log to deterministic application services. Separate services can own different business domains and release on their own schedules, with replay supporting reconstruction and investigation. The published design includes active/active and active/passive service modes, snapshots, operational tooling and deployment on dedicated hardware or cloud infrastructure without a multicast dependency. These are architectural facilities for a trading system, rather than an assertion that every customer application will behave deterministically without appropriate design.[6]

Transport Security is an optional Premium component with a precise compatibility boundary: it operates in the Aeron C media driver and requires OpenSSL 3.0.0. Drivers use configured public/private keys for authenticated communication. After the security bindings are enabled, publications and subscriptions are secured by default unless explicitly disabled per channel. The Java driver rejects ATS channel parameters. The choice of client language and the choice of media driver should therefore be specified separately during integration.[10]

The priced AWS row does not define a node, server or throughput allowance. Its scope belongs in the offer. That listing states that the licence can be terminated with 90 days’ written notice; it does not promise a particular refund. Its public amount is a specific marketplace contract price, not a tariff for every Adaptive project.[15]

The priced listing links the November 2023 AWS Standard Contract. It incorporates the product listing and agreed amendments; amendments take precedence. The grant permits use within the buyer’s business and alongside its products, while retaining the supplier’s software ownership. Bespoke application ownership and source access should therefore be recorded in the applicable project agreement.[17]

The Exchange Accelerator separates Adaptive’s source-available components from bespoke customer IP. Its optional managed service covers maintenance, updates and infrastructure. Cloud, hybrid and on-premises options leave hosting and operating responsibilities to the selected engagement; source access does not transfer Adaptive’s ownership.[7]

Adaptive’s ADSS case study gives a concrete example of the customer/vendor division. The new platform used the broker’s pricing engines and market connectivity, while supplying OMS and pre-trade risk functions. Adaptive coordinated interface development with changes to downstream systems and automated web/mobile testing. It reports nine months from conception to the web client’s production delivery, including analysis, design, development, testing and deployment. That is the reported project outcome; it is not a standard implementation commitment.[18]

Operational access extends beyond dashboards. The documented Cluster Tool can describe a running cluster, inspect membership and recorded state, request snapshots, list errors and initiate a clean shutdown. A production handover therefore needs to allocate authority over these commands and preserve the relationship between the cluster directory, archive and deployment configuration.[19]

The current commercial hierarchy distinguishes SLA-backed Premium support from the enterprise Platform’s stated 24/7 Aeron support. The public hierarchy does not publish a universal incident-response or restoration time. The selected agreement should identify supported versions, escalation routes and coverage for the customer’s application as well as the supplied components.[4]

Aeron Insights is explicitly a beta release. It exposes application health through Prometheus exporters, an example Grafana dashboard and a command-line analysis tool. A local example is provided for evaluation. Teams adopting it should retain its beta status in their operational design, rather than assume the dashboard is an established production support entitlement.[14]

The security disclosure policy gives a separate response expectation: Adaptive says it will respond to vulnerability emails within two business days, then provide an expected timeline after triage. Affected-party notification depends on a validated issue’s severity and complexity. This security-reporting process is distinct from an application-outage SLA.[21]

Adaptive supplies software and engineering. In the documented ADSS deployment, the broker supplied pricing engines and market connectivity. The commercial relationship described here therefore concerns a firm’s technology estate; the operating broker’s dealing, customer-money and market-access arrangements remain distinct from the software procurement.[18]

Aeron’s trademark policy separates permission to use, modify and distribute open-source code from permission to use the brand. It permits factual compatibility references, but imposes separate rules on modified distributions, product naming and approved “Powered by” branding. A customer building proprietary technology should preserve that distinction in external presentation and distribution arrangements.[27]

For the listing-linked Standard Contract, expiry ends the purchased software-use rights. Its 45-day data-return or assisted-retrieval mechanism is expressly for SaaS subscriptions, with a written request for provider extraction before termination or expiry. It should not be presented as an automatic hosted export service for the separately listed customer-deployed container. The purchased delivery model and any negotiated amendments govern that distinction.[17]

Adaptive began in 2012 as a capital-markets engineering consultancy, following the founders’ work on an FX single-dealer platform. Its 2022 acquisition of Real Logic brought the Aeron creators into the business. The company subsequently combined custom engineering with reusable trading infrastructure, rather than requiring each project to recreate the same messaging and resilience components.[25]

The group statement for the year ending June 2025 names Adaptive Group Technology Ltd and operating entities including Adaptive Financial Consulting Ltd, Adaptive Financial Consulting Inc., Adaptive Consulting SLU and Technologies Adaptive. The website privacy notice identifies Adaptive Financial Consulting Limited and its affiliates. The relevant contracting entity should be identified in the order or statement of work.[24][23]

On 5 March 2026, Adaptive announced that it had secured strategic investment from HSBC and Citi. It said the funding would expand Aeron-centred product development and delivery capacity. Commercial terms were undisclosed; the announcement does not establish either bank’s ownership percentage or control.[26]

The privacy notice, updated 30 May 2025, addresses website and contact information, including enquiries and marketing interactions. It ties retention to the relevant purpose and lawful basis. Production trading data, deployment access and the operational supplier’s processing responsibilities require the applicable service documentation; the website notice is not a trading-data retention schedule.[23]

Version 1.53.0 introduces specific migration work. Aeron removed the Java-agent event-logging requirement and changed logging formats; dynamic logging enablement is no longer supported. It also removed previously deprecated Image methods and changed C/C++ Archive error-code interfaces. Existing log parsers, launch configuration and client code may therefore need updates. The release note provides a practical example of why a supported-version policy and regression testing belong in an ongoing operating arrangement.[20]

Retention Regulator is a technical storage-control tool, despite its name. Its recovery policy retains the necessary log after the oldest selected valid snapshot and avoids deleting recovery data before the recording log is available. A firm still has to map its recordkeeping obligations and investigation needs into the chosen policy. Keeping enough state to restart an application and keeping a legally sufficient business record are separate requirements.[13]
