fourTheorem

fourTheorem is a technology consultancy founded in 2017 that helps businesses adopt cloud and serverless technologies, with particular depth in AWS. Its work spans serverless architecture design and implementation, cloud migration and modernisation from traditional IT to cloud-native approaches, container technologies, and high-performance computing (HPC) workloads running on serverless architecture - a practice in which the firm was among the first to succeed. The stated aim of these engagements is to cut infrastructure costs while improving scalability and developer productivity.

The company holds AWS Advanced Consulting Partner status and three AWS specialised competencies: serverless computing, migration services, and container technologies. Its client work covers financial services, energy, healthcare and academia.

fourTheorem operates as a fully remote, distributed team. Its approach emphasises collaboration with client teams, knowledge transfer and sustainable outcomes rather than long-term dependency. The founders come from backgrounds in successful startups and deep AWS expertise.
