I took a look at your CRM product and understand that your long term goal is a great ecosystem...however, your UI is missing the point of a modern CRM.
A CRM used to be account/contact/opportunity tracking. Now, sales teams use CRM as the de facto customer-focused data warehouse (because no one in sales actually knows how to query a data warehouse). These days I rarely use salesforce for anything besides looking up data that was written there by another sales tool via the API. The product focus should be on developing a great analytics solution for salespeople, not an online Rolodex.
I used to work at Salesforce and have deployed it at multiple startups as the founding head of sales. Shoot me an email if you want to talk more; I'm looking forward to the day that Salesforce is replaced by something that better fits the modern sales process.
I'm interested to know how much time you've actually spent using CRMs or ERPs yourself. Not clicking around and exploring features, but actually using for something.
While I know this is a very early release, my biggest concern is naivety about real world usage requirements, and if you'll be able to manage the feature creep that will be coming with it without just turning into another Salesforce or NetSuite.
As soon as you get users it's going to get harder to add in those things you're putting off thinking about until later, and managing it will become a legacy suckfest. This manifests itself in a slow, slow, slow experience and necessary UX decisions that make the user scratch their head.
I'd say the biggest example of this is custom fields. It's not just another problem to solve at some point, it's probably one of the biggest ruins of CRMs.
