Short answer. Yes. The Civil Code makes a stranger to your contract answerable in damages if he induced the other party to violate it. You are not confined to suing the party who broke the agreement; the outsider who engineered the breach can be made to answer directly to you.
What the law says
Any third person who induces another to violate his contract shall be liable for damages to the other contracting party.

An exception to the usual rule
Contracts normally bind only the people who signed them, which is why a stranger cannot ordinarily be sued on an agreement he is not part of. This provision is the deliberate exception. It does not make the outsider a party to your contract, and it does not let you demand that he perform what the other side promised. What it gives you is a claim in damages against him personally, for the loss caused by his interference. That distinction matters when you decide what to ask for: performance and rescission are demanded of your counterparty, while money for the harm can be pursued against the interferer alongside them.
What you would have to establish
Three things sit at the centre of the claim. There must be an existing, valid contract — the provision speaks of inducing another to violate his contract, so negotiations that never ripened into an agreement are a different problem. There must be a violation of it. And the third person must have induced that violation, meaning his conduct moved the other party to break it, and he acted knowing the contract was there. Someone who did not know an agreement existed has not induced its breach in any meaningful sense. You will also need to show what the interference actually cost you, because damages have to be proved rather than assumed.
Where legitimate competition ends
Not every lost deal is actionable. A rival is generally free to make a better offer, advertise, hire in the open market, and compete for the same customers. The provision is aimed at conduct that goes beyond that — persuading someone to walk away from a commitment he is already bound by. In practice the difficult cases are the ones where the outsider had some interest of his own to protect, or where the counterparty was already looking for a way out and the outsider merely gave him a place to go. Motive, knowledge and the sequence of events tend to decide these disputes, which is why the correspondence matters more than the recollection.
What to preserve now
Keep the signed contract and every amendment, along with proof that the outsider knew of it — copies furnished, references in emails, mention in meetings. Collect the communications that show the approach: messages between the outsider and your counterparty, the timing of the new arrangement, and any inducement offered. Document your losses concretely: cancelled orders, replacement costs, idle capacity. Claims against the party who breached and against the interferer can raise different issues and different defences, so have both assessed together before filing. Every dispute turns on its own facts, and nothing here forecasts how a particular one will be decided.
