The Voxelgrids journey – from inception to reality


Over the Years


New Beginings

  • Company founder Arjun Arunachalam studied at the University of Wisconsin-Madison from where he received his MS and PhD degrees.
  • From 2006-2008, he worked at the GE Global Research Center, Niskayuna, NY.
  • He resigned from GE research in October 2008 with the intent of eventually starting an entrepreneurial venture.

Exploring Opportunities

  • One year of gathering market understanding
  • Establishing relationships with potential investors, vendors and other partners

Initial Challenges

  • One-year long attempts to raise funding futile.
  • Joined IIT-B as a faculty in EE and continued to work in the field of MRI despite obvious challenges that existed due to MRI being a completely nascent field within India academia specifically in an engineering context.
2013 April

  • Arjun’s wife Nivedita was offered an excellent opportunity in Singapore and so their family relocated.
  • While in Singapore, Arjun received a Grant from Spring Singapore for developing MRI related intellectual property
  • A small test scanner platform for MRI was built from this grant for initial proof of concept tests
2016 May

  • Contacted Tata Trusts and shared his proposal for building cost effective, state of the art Magnetic Resonance Imaging scanners in India.
  • The Trusts were supportive and introduced Arjun to the Foundation for Innovation and Social Entrepreneurship (FISE),.
  • The Voxelgrids journey eventually started under FISE where the core team was employed during the initial years.

First Steps

  • Voxelgrids team worked as FISE employees and developed a proto-MRI scanner. This prototype was deployed in mid 2017 at The Sathya Sai Institute of Higher Medical Sciences, Bengaluru, under an MoU signed between the two parties.
  • The first set of images from this scanner were obtained in March 2018.

In mid 2019, Voxelgrids received a significant grant from the Biotechnology, Industry, Research , Academic Council (BIRAC) for development of indigenous cryogenic magnet and MRI technologies. The company was previously awarded a grant by the United States-India Science & Technology Endowment Fund as well. The company was also a recipient of the BIRAC Innovator award 2020 that was presented by the Vice-President of India.  This enabled the company to take its first independent steps towards operating as an independent entity. Subsequently, the company was ISO 13485 certified in mid 2020.

In 2021, the company closed on its series-A funding with Zoho Corporation, a privately held multi-billion-dollar software company. Voxelgrids today is an independent entity  supported by multiple stakeholders and is on a mission to provide cost effective, state of the art Magnetic Resonance Imaging scanners for the world markets.
