Can tell you spend a lot of time on it, and it shows- the UI is simple but slick.
That said, here are some thoughts:
The main page of the site isn't really getting at what it is. It isn't a personal assistant. It is a somewhat easier to use web-based Outlook Web Access-like saas. Maybe something like "Makes online email and task management easy."
About the bullets:
* Auto-dial any contact in your addressbook in a single click
could be rewritten as "Auto-dial your contacts with a click"
* Auto-scan & organize your important email sent from real people
becomes: "" (nothing) If it is a web-based email client, right? I don't understand this auto-scan thing at first glance and neither will your customers.
* Auto-sync your contacts to your iPhone, Blackberry & Android devices
Sounds neat, but without context it doesn't sound revolutionary. My first thought was, "Can't anyone just do <a href="tel:111-222-3333">111-222-3333</a> to do that?" and the second was "Does that work with Skype, etc.?" I think you'll need to specify the GMail phone thing.
* Auto-delegate tasks to friends & coworkers
This sounds like it's a bit out of focus with the goal of a simple web-based dashboard for email and personal/business tasks. Is it a personal task management and email/contacts app, or is it a task management system like Jira? I'd focus on the former and axe this.
Nothing mentioned about low-cost on front page like "Cheaper than Outlook and connects to your Gmail, Yahoo Mail, Hotmail, etc.".
All in all though, I personally wouldn't have interest in it, and I can't really think of anyone I know that would. I think that basically it's main purpose seems to be a wrapper around Gmail to provide an even simpler UI and task assignment/management.
I think it seriously needs something it does that nothing else can do, that is of serious value to the small business owner (which it seems to be targeted at).
I don't see it as a real CRM, and with Sugar CRM, Salesforce, etc. you'd have to make that the primary focus.
I understand it was in use at another startup, but I really think you need to seriously pick something for it to be really good at, and beef that up.
Good work though! Looks nice!
