Bengaluru startup Voxelgrids saved by Tata Trusts and Sridhar Vembu

Business Aug 07, 2026

Voxelgrids, a Bengaluru startup, nearly shut down while building India's first locally made MRI machine.

Founder Arjun Arunachalam turned down a big offer from a multinational to protect his innovation.

Thanks to timely support from Tata Trusts (led by Ratan Tata) and Zoho's Sridhar Vembu, the project survived and moved forward.

Voxelgrids MRIs 40% cheaper 50% lighter

Voxelgrids's MRI machines are 40% cheaper and 50% lighter than imported ones, using smarter designs and nitrogen instead of pricey helium.

With India spending ₹3,500 crore each year on imported MRIs, this tech could cut scan prices by 70%, making advanced diagnostics more accessible, especially for underserved communities.
