Kato works is a manufacturer and so is ACE. Sanghvi movers rent out the equipment.
It’s like Maruti Suzuki who makes car. They can’t be direct threat or competition to Ola/Uber of the world.
Actually it may not be even that much. In my limited understanding about ACE, they don’t manufacture what Sanghi rents out which is typically heavy lifting equipment. There could be little overlap in what one makes and other uses but ACE is definitely not in its main suppliers list.
