Hiring From a Competitor: Onboarding Without Inheriting a Lawsuit

Before the offer goes out

• Ask whether the candidate is bound by anything — and get the documents. Non-compete, non-solicit (customer and employee), confidentiality and invention-assignment agreements, plus any equity or bonus clawbacks. Candidates routinely underestimate what they signed. Read the actual paper, not the recollection.
• Assess enforceability for this role, in this state. Whether a covenant binds turns on its scope, the employee’s role, the consideration given, and the jurisdiction — and this is an area in real flux, with several states narrowing or banning non-competes and the federal picture unsettled. Confirm against the current rule rather than assuming the agreement is either ironclad or worthless. See Restrictive Covenant Review.
• Map the covenant to the job you are actually offering. Risk concentrates where the new role overlaps the old one — same customers, same territory, same product line, same team. A title change does not cure overlap; the work does.
• Decide the risk question before you fall in love with the candidate. Some hires are worth a fight; some are worth a tailored role; a few are not worth the exposure at all. Make that call while you can still walk away, narrow the duties, or route it to counsel.

Set the rules in writing — before day one

Verbal instructions do not survive discovery. The clean-hands posture has to exist on paper, dated before the new hire has access to anything.

• Instruct, in writing, not to bring or retain the former employer’s information. No files, no customer or pricing lists, no source code, no decks, no contact databases — nothing physical or electronic, and nothing sitting in a personal email account, cloud drive, phone, or thumb drive. The rule is return or delete, not “keep just in case.”
• Instruct not to use or disclose the former employer’s confidential information — including from memory. General skill and experience travel with the employee; specific confidential and trade-secret information does not. Say so explicitly, so the line is the company’s and not the new hire’s to guess.
• Instruct not to solicit in violation of a valid covenant. If an enforceable non-solicit covers customers or coworkers, the new hire stays off those names for its duration. Where a covenant is narrow or unenforceable, say what is permitted — silence invites the employee to guess wrong.
• Tell the new hire not to recruit former colleagues on the company’s behalf. A team “lift-out” is the fact pattern that turns a single departure into a coordinated-raid claim — and reframes the company from bystander to architect.

Shape the role to lower the exposure

• Tailor initial duties for high-risk hires. Where overlap is sharp, start the new hire on different accounts, a different territory, or non-competing work for an initial period. This both honors a valid covenant and undercuts an “inevitable disclosure” theory — the argument, recognized in some states and rejected in others, that the role cannot be performed without drawing on the former employer’s secrets.
• Wall off the obvious flashpoints. Keep the new hire out of decisions that turn on the competitor’s confidential pricing, roadmap, or customer terms during any restricted period. Brief the hiring manager too — the casual ask to “tell us what they were charging” is what creates the problem.

Get the acknowledgment and document a clean start

• Obtain a written clean-hands representation. Have the new hire confirm they have returned all former-employer property, retained none of its confidential information, and will comply with any valid surviving obligations. This is protection for the company and a genuine reset for the employee.
• Scrub the first-week intake. No forwarding of old work email, no uploading personal drives or contact exports, no “starter” templates carried over. Provision company devices and accounts clean. The first days generate the evidence either way.
• Keep the onboarding record. The signed instructions, the representation, and the role description — dated and filed. If a letter arrives, the difference between a quick resolution and a costly one is often whether the file shows the rules were set up front.

Higher-risk situations

• Route close calls to counsel before extending the offer. An enforceable-looking covenant, a senior or customer-facing role, a direct competitor, or a multi-person move — any one of these is worth a privileged look before commitments are made.
• Consider proactive notice to the former employer. In the right case, a measured letter — confirming the new hire’s scope, that no confidential information was taken, and that any valid covenant will be honored — can set a cooperative tone and defuse a dispute before it forms. It is a judgment call: it also puts the other side on notice, so weigh it with counsel.
• Have a forensic plan ready if a threat lands. Preserve devices and accounts, suspend deletion, and resist the instinct to “just check” what the new hire brought — that is for counsel and a neutral examiner to handle, not the manager.
