Pathfinding is the practice of starting from the buyer you want to reach and working backwards to find who in your network can get you in. It is the inverse of traditional prospecting, which works forward from the contacts you already have and hopes one of them is relevant.
You name the target: a person, a company, or a whole list. Pathfinding then searches your extended network for the connectors who can reach that target, and surfaces the shortest, strongest warm paths in. The ranking depends on relationship intelligence: how real and how recent each tie is, not just whether a connection exists.
The payoff is reach beyond your first degree. You know your own connections, but not who they know, and that second degree is where most warm intro opportunities are hiding.
Prospecting asks "who can I contact?" and produces a list. Pathfinding asks "who can get me in?" and produces a route. As cold volume stops working, teams are shifting from one to the other; the move from prospecting to pathfinding is the larger trend behind warm outbound.
Pathfinding is what Via does. You ask in plain language who can get you into an account, and Via works backwards from that target to surface the strongest connectors, including second-degree paths you would never find on your own.
