We take research seriously

In early 2023, fourTheorem secured exclusive access to intellectual property rights – focusing
on the application of AI in software architectural transformation – developed in conjunction with DCU and Lero.

The deal enables fourTheorem to commercialise all output from the Future Software Systems Architectures (FSSA) project, which set out to address a vital issue in the world’s software market: How to reduce the risks and costs associated with migrating existing ICT systems to modern, microservices-based architectures – traditionally a manual, expensive and error-prone process.

Machine Learning-based Automatic Architectural system

Fission systemically identifies and extracts services from monolithic architectures, enabling the rapid migration of legacy applications to a modern cloud-native architecture.

How it works


  • Build and run codebase
  • Build and run collection
  • End-to-end testing


  • Pre-process data
  • Detect entry points
  • Identification algorithms


  • Extract candidate services
  • Generate services deployable components

CEO, Peter Elger:

“With Fission, we can rapidly accelerate the uncoupling of structures and dependencies within existing monolithic platforms – saving our clients time, money, and crucially, de-risking those first steps away from the monolith environment into a microservices and serverless future.”

About the FSSA Project

The FSSA project examined the application of AI to software architectural transformation, notably in microservices extraction from monolith-based architectures.

The consortium behind the FSSA project, led by fourTheorem and directed by Dr Paul Clarke and the late Professor Rory O’Connor, comprised leading-edge researchers from DCU and Lero. Dr Andrew McCarren from DCU and Insight, the Science Foundation Ireland Research Centre for Data Analytics, was co-Principal Investigator on the research programme.

The project was jointly funded – to a total of €2.1M – by fourTheorem and the Disruptive Technology Innovation Fund (DTIF). DTIF, a €500 million challenge-based fund established to drive collaboration between Ireland’s world-class research base and industry, is managed by the Department of Business, Enterprise and Innovation and administered by Enterprise Ireland.
