About VFunction

VFunction operates as a specialized software firm addressing architectural technical debt for large enterprises. Founded in 2017 by Moti Rafalin, Amir Rapson, and Ori Saporta, the company is headquartered in Menlo Park, California, with additional offices in Israel, London, and Austin. The founding team carries a history of collaboration, having previously established and led WatchDox, a data security company acquired by BlackBerry.

The company's core offering is an AI-driven Architectural Observability Platform designed to help organizations modernize monolithic legacy applications and govern microservices architectures. VFunction's business model centers on licensing its platform on a per-application basis, targeting enterprises struggling with the complexity, cost, and risk associated with manual application modernization. By automating the process of transforming complex Java and .NET applications into microservices, the platform aims to restore engineering velocity and enable businesses to leverage cloud-native benefits like elasticity and scalability. The platform caters to software architects and engineering teams, providing them with tools to visualize application architecture, identify and prioritize technical debt, and manage the modernization process across a portfolio of applications.

The VFunction platform functions by deploying agents that perform dynamic and static analysis of an application's code and dependencies. It uses data science and AI to identify functional domains and recommend how to break down the monolith into deployable microservices. Key features include automated architectural discovery, dependency mapping, technical debt analysis, and tools for refactoring and extracting services. The platform also provides governance capabilities to monitor architectural drift in distributed systems, helping teams enforce design standards and prevent the growth of complexity in microservices environments. A GenAI-powered assistant is integrated to guide developers through remediation and refactoring tasks. VFunction has secured a total of $38.2 million in funding over two rounds, with a significant Series A round of $26 million in late 2021. The company partners with global system integrators and cloud providers like AWS to reach its enterprise client base, which includes major firms in the financial services and technology sectors.
