What do you like best?
I like that they allow users to easily update contact information. If you do a Google search of a specific person, who you know is at a different company, 9 times out of 10, you'll find that all search results display the past company and there's really no way to change that without opening a support ticket. With Connect, you can create an account and update the title, company, email, etc. without going through all of those extra steps.
The user interface feels simple like Salesforce Classic, which makes it very easy to navigate the site. The advanced search is also a powerful feature with many filters, which makes it a great tool for refining your target industry/role.
What I like best about Connect is that it's technically free to use. You can purchase points to buy actual contacts, but I find it much more worthwhile to create an account and generate points by adding or updating contacts and companies.
What do you dislike?
Because anyone can create an account and earn enough points to add or update an unlimited amount of contacts or companies, the system ends up being abused by many individuals, and ultimately impacts the data quality. Connect has an option that allows you to mass import contacts, but from my experience, I don't believe you can compare each contact to that of one that already exists in Connect. For example, if you're importing an old list with contacts who no longer work at a certain company, these contacts may be marked as "Left the Company" in Connect, but the import will reverse this and show them as active.
That being said, Connect has been responsive and proactive in preventing users from abusing the system and adding incorrect data, but you will often find duplicate contacts or incorrect data for specific contacts.
Recommendations to others considering the product:
Not all data will be accurate. Be wary if you see a user name with a Lock icon next to it, because that means his/her account has been locked (typically for importing bad data, adding nonexistent contacts, etc.).
What problems are you solving with the product? What benefits have you realized?
Before Connect, we were collecting this data manually, which was incredibly time-consuming and not 100% reliable. Connect afforded us substantial savings in time and effort to research prospective customers.
