Multiple collections with different landing pages for different customer

Store Design
1

Hello,

I wonder if anyone can help.

I am looking to create a b2b store. The store will require multiple collections with multiple landing pages specific to a customer. Is there an application that can do this.

i.e. one customer is directed to a certain landing page connected to a certain collection & another customer is directed to an alternative landing page with the relevant collection.

I have looked at redirector but the redirector is based on geolocation and all our customers are in the UK.

Any help would be useful.

Thank you.
