I always sign as the LLC. I work at a family office and invest with searchers. As an individual I am just one of many people that will be bound by the NDA. Typically, they loop in your legal and financial consultants as well. The LLC signing makes that clear to any 3rd parties that are working for the LLC and not me as an individual. Just don't steel customers or employees and it will never come up.

Hi. Typically, you would sign in the name of the firm that is entering into a transactional review, but virtually all NDAs impose the obligations on both the entity, and all of its corporate affiliates, including agents and representatives. Often, the entity is required to provide oral or written disclosures to its affiliates to whom confidential information is provided under NDA with all of the obligations they are required to uphold, and the failure of the entity to do so can create liability. As NDAs become more sophisticated, it is a good idea to have them reviewed by counsel. Sometimes, companies try to put in liquidated damages provisions such that if the NDA is breached, you can end up owing a significant amount of money as a penalty.
