Company Timeline

Continuous innovation is at the heart of Axion

At Axion, we empower our scientists and engineers to develop the tools that enable new discoveries and better therapies. Our company timeline below outlines how we evolved from a graduate research project into a leading life science company. Even with this growth, we never lost our spirit to create, continuing to expand our products to keep helping scientists find answers to their big questions. All the time keeping in mind our goal: to make the complex accessible.

Tom and Jim with first microelectrode array device


Tom O’Brien and Jim Ross Ph.D. found Axion BioSystems in Atlanta, Georgia, based on technology licensed from Georgia Tech.

2010 Must


Introduced the Muse, Axion’s first MEA system, which used the first generation of Axion’s BioCore chip. This product introduced scientists to plug-n-play MEA research with no compromises in assay flexibility.

2011 Maestro


Introduced the Maestro, the world’s first multiwell MEA system. For the first time, scientists could recreate “heart beats” and ”brain activity” at scale, collapsing months of experiments into a few weeks.



Expanded multiwell MEA plate portfolio from 12-well, adding 48- and 96-well options. Now, scientific exploration of excitable cells could move even faster, generating a year’s worth of the experiments in a few weeks.

2015 Apex


Introduced the Maestro APEX automated MEA robotic system.  APEX streamlines every stage of the MEA experiment from plate preparation, routine culture maintenance, compound addition, and running Maestro experiments.

2015 Lumos


Introduced the Lumos 48, the world’s first multiwell optogenetic stimulation system.  Lumos  is a standalone device and also pairs with Maestro system allowing patented light-controlled MEA experiments.

2018 Maestro Pro and Edge


Introduced Maestro Pro and Maestro Edge, Axion’s second generation MEA system. Built on Axion’s latest chip technology, BioCore v4, Pro and Edge also feature “one button setup,” inbuilt environmental control, and barcode scanner for experimental tracking. 

2018 LEAP


Introduced the new LEAP assay™ to Maestro Pro and Edge. For the first time, LEAP allows label-free cardiomyocyte action potential recordings in an MEA plate.

2019 Contractility


Introduced Contractility, the second new assay for Maestro Pro and Edge. The first high-resolution contractility assay, allowing up to 64 contractility measures in each well of a multiwell plate.

2019 Maestro Z


Introduced the Maestro Z, the world’s most advanced impedance-based cell analysis system, for label-free oncology, virology, cellular kinetics assays. Featuring an integrated environmental chamber, plate barcode scanner for automated plate tracking, and the next generation in analysis software.

2020 Maestro Z App


Introduced the Maestro Z App for smartphones.  The Maestro Z App was the first app which allows real-time updates of assay data on your smartphone.

2020 Software Modules


Introduced the Neural, Cardiac, and Impedance Software Modules for Maestro Pro and Edge.  Now you customize your Maestro MEA system with the software to meet your assay needs.  Software upgrades after purchase are now also possible.
