Scaling Simplicity

Complexity limits your organization’s potential

For over a decade, we’ve built high-quality, scalable, and resilient software systems for the world's largest companies, without fail.

Our Services

Software Engineering

Delivery-focused software engineers that build high-quality, adaptable systems:

Elegant solutions based on research and creative problem-solving

Well-tested, robust, efficient applications

Cloud-native backend engineering, with modern frontend UX

We can join your existing engineering staff or run dedicated JUXT teams. Our projects succeed because we work hard to understand the mission deeply and our engineers take ownership.

Architecture Design & Review

We've designed data-intensive, realtime systems, solving tough architectural problems in finance and many other domains. We bring the philosophies of functional programming to the architecture - treating time as a first-class concern; treating data as immutable at all levels of the stack; promoting stateless systems and operations.

We've designed and delivered event-driven and API-driven systems, taking careful advantage of the capabilities of the modern cloud.

We consult on existing systems to provide short and long-term recommendations for increasing scale and evolving towards new use-cases.

Platform Engineering

JUXT has helped Fortune 500 companies get developer tooling right. We deliver cutting-edge Internal Developer Platform projects, allowing organisations to improve the efficiency of engineering at scale.

Platform engineering done right can give your software teams:

Compliance, security, and other non-functional guarantees, at scale

Delightful internal developer experiences and documentation.

An internal 'open source' culture and a thriving community of contributors.

Cloud Infrastructure

We’ve been building systems on AWS since early 2014, over that time we’ve accumulated first-hand knowledge and expertise of managing and automating AWS infrastructure through code.

Our AWS systems have been successfully audited for PCI DSS compliance and won praise for their operational stability, information security and regulatory compliance. We have experience in meeting GDPR requirements and protecting data privacy.

Our Approach

The fundamental concerns in IT systems are time, data, form, and code — their subtle interactions and couplings combine to have a suffocating impact on software projects.

Our approach to building IT systems is defined by a unique methodology and a set of supporting tools that allow us to keep these four concerns separate, resulting in:

Rapid development of large IT systems

Increased levels of agility and software re-use

Lower maintenance costs

Secure, reliable systems that are robust yet flexible


We believe that systems should be built on the conceptual bedrock of a dual timeline. This provides a universal set of essential capabilities for organizations who operate within disparate and ever-evolving landscapes of information, and who require an accurate and consistent view of information at any point: past, present and future.

The main timeline is fully controllable and it allows for:

Historical corrections

The integration of imported records

The previewable orchestration of future states

The secondary timeline is immutable and provides a guaranteed audit trail, 'built-in'.



Data is fundamental to the creation of software. It will routinely outlive the interpretations we derive from it and the applications we build on top of it. Therefore, we will always seek to lay the foundations of data management independently of a particular application or use-case, and above a common timeline.

Table-based structures, found in spreadsheets and traditional SQL databases, are helpful for displaying and analyzing data, but they are not an appropriate format for storing data.

Tables are insufficient for representing data in its purest form, and this is particularly obvious when modeling sparse data or multi-valued attributes, or coping with the evolution of data over time.

Instead, we believe that data is best recorded as units of facts and relationships, without constraints.

Simply put, we believe graph-oriented systems point us towards the correct approach for data management, and organizations, such as Facebook and Google have proved how powerful the widespread use of graph-structured data can be.


Organizations can unlock different amounts of value from data depending on how they interpret it, how they shape it and the constraints they place on it.

Complex types & tables, schemas & structures, classes & containers, models & metadata, formats & encodings, representations.

These are the forms we construct for interpreting, analyzing and extracting value from our data. Tools such as relational schemas and ontologies are common structures we use for understanding, analyzing and managing our information.

Too often, software developers will attempt to "codify" these structures into their software as types and objects.

By understanding that schema is just another form of data, on a timeline, we let our information systems grow and flex with the businesses they serve. This is how we are able to build maintainable models of the real world.



The software patterns and practices that underlie your application architecture are certainly important, but less fundamentally relevant than making the correct choices with regards to the structure of your data in time. Assuming those other foundations are in place, we believe that the best approach to code is to keep it short, readable and expressive.

In reality this means we prefer:

Writing modular & generic libraries of functions that operate over many types of data structures

Minimizing the use of state wherever possible

Maintaining declarative structures that avoid the need for reasoning about imperative control flows

By pulling out the state and domain, the remaining code is simple. Developers can focus on writing code to implement business logic, pure functional calculations and derivations, with resulting actions that automate the execution of business processes.

As software complexity is tamed, productivity soars.
