Our Mission


Our goal is to create a smarter and safer world by enhancing the connection between software-driven products and our physical environment. Xronos specializes in design automation for cyber-physical systems that are software-defined, data-driven, and enhanced with AI. We make it easier and faster to build capable and reliable software for cars, robots, electric grids, factory floors, and space tech—anything that runs complex software and interacts with physics.

We eliminate the overwhelming complexity that arises when software-defined, data-driven, and AI-enabled systems interact with the physical world. Ad-hoc system integration strategies result in solutions that are fragile, poorly modularized, and unsuitable for use in critical safety environments. We believe the only way to scale software-defined systems is to overcome these challenges through design automation, clear abstractions, and separation of concerns.

Our technology separates application logic from coordination logic, allowing software engineers to focus on their application, instead of tracking down subtle concurrency bugs, manually implementing parallel or distributed programs, or endlessly hacking their code to meet real-time requirements. Instead, we automate the coordination between software components, following a well-defined model of computation that is deterministic, free of deadlocks and race conditions, and enables the detection and handling of missed deadlines.

Xronos makes it easier and faster to develop, test, and validate code, build new systems out of existing components, and derive meaningful and transferrable value from simulation.

Marten Lohstroh
Co-founder & Chief Executive Officer

Marten has led the development of the Lingua Franca coordination language since its inception in late 2019. He received a B.S. degree in computer science (2009), a M.S. in grid computing (2013), both from the University of Amsterdam, and holds a PhD in computer science (2020) from UC Berkeley. His dissertation titled “Reactors: A Deterministic Model of Concurrent Computation for Reactive Systems” laid the groundwork for the Lingua Franca coordination language.

Christian Menard
Co-founder & Principal Architect

Christian recently obtained his PhD from TU Dresden in Germany and has been contributing to the Lingua Franca project since its early stages. He is an experienced compiler and embedded systems engineer with a strong focus on clean abstractions.

Jeff C. Jensen
Co-founder & Head of Engineering

Jeff C. Jensen is a technology leader and electrical engineer with 20 years experience developing hardware & software products. He ran product innovation in mechatronics at National Instruments, then served as VP Engineering at the robotics startup Creator, building the world's first fully automated commercial kitchen. As CTO at Blackrock Neurotech he led technology vision, strategy and execution of a team of over 100 scientists, engineers and technicians building the world's only in-human implantable brain-computer interfaces. He is Head of Engineering at Xronos.

Edward A. Lee
Co-founder & Chief Scientist

Edward A. Lee has been working on embedded software systems for more than 40 years. After studying and working at Yale, MIT, and Bell Labs, he landed at Berkeley, where he is now Professor of the Graduate School in EECS. His research is focused on cyber-physical systems. He is a founder of the open-source software projects Lingua Franca and Ptolemy and is a coauthor of textbooks on embedded systems, signals and systems, digital communications, and philosophical and social implications of technology.

Jeronimo Castrillon
Co-founder & Advisor

Jeronimo is a professor with the Department of Computer Science, TU Dresden, where he is also affiliated with the Center for Advancing Electronics Dresden (CfAED). He is the head of the Chair for Compiler Construction, with research focus on methodologies, languages, tools and algorithms for programming complex computing systems. In 2014, he co-founded Silexica GmbH/Inc, a company that provides programming tools for embedded multicore architectures now with Xilinx/AMD. Prior to that, he obtained degrees from Pontificia Bolivariana University, Colombia, the ALaRI Institute, Switzerland, and RWTH Aachen University, Germany.

Erling Jellum
Embedded Systems Engineer

Erling is an embedded software engineer experienced in developing time-sensitive hardware and software. He is a co-founder of SentiSystems and has a PhD from NTNU in Norway. Erling has been working on Lingua Franca since 2022.

Peter Donovan
Software Engineer

Peter is a junior software engineer. He studied computer science at UC Berkeley and has been working on Lingua Franca since 2021.
