Who signs? If it's the firm, expect a demo, an implementation and a seat count. If it's you, expect a card form and a free tier. Nothing in this category straddles the two, which is why the price ranges look absurd side by side: $0 to $2,700 per person per year for tools that all describe themselves as relationship management.
Where does the relationship data come from? The firm-wide products capture every partner's work email and calendar into one permissioned graph. DealCloud describes it as automatically creating and maintaining records discovered through the firm's email communications, with zero-entry activity capture. That is powerful, and it's work email only: your personal accounts, the LinkedIn connections you made before the fund and the founders you follow aren't in it.
Is there a price at all? Of the six competitors here, Affinity and Attio publish a full price, Visible publishes the founder side only, and 4Degrees, DealCloud and Decile Hub publish nothing. That tells you what buying will be like.
Whose network is it when someone leaves? A firm-wide graph belongs to the firm, which is the point of it. A partner's own connections predated the fund and will outlast it, and most firms have no system for those at all.
