Looking for CRM

I am curious if anyone might have some recommendations for a CRM platform that integrates with Squarespace, ideally a CRM that works well for Real Estate Brokers?  Thanks 

I am interested in this topic and well. Over on Shopify, they all but require Kit CRM. Anything like that here? TIA!

I'm currently setup with Dubsado and it's been a really good experience. It also connects with Zapier
