Hi Siddharth,

What kind of information you need. Is it something like which you can achieve through Master-Detail Relationship, then you can use any of the below 2 AppExchange product both are good and can be used with Lookup Relationship Thanks,

Depends on how you plan to use values. If you want to updeate the parent object's field , you can do it either using a Process builder or a trigger. Or if you just need a rollup of a child object's field, then that can be achieved by a Master Detail relationship like Nagendra suggested.
