We do not. Investors are not notified when you add them to Investor Tracker, and people in your network are never contacted or messaged without your permission.
The only communications that occur with people outside of Foundersuite are when you send your contacts a specific request-- for example, when you are seeking feedback on your company in the Idea Validation module, or when you publish your Progress Report to investors, advisors, or others in your network.
In short-- you control all communication flows in Foundersuite.
