The only thing I see limiting is not being able to mention a well-known client’s name. Large consultancies sign NDAs all the time, with hundreds of clients spanning every type of project one can imagine. There are countless overlaps between these projects. And of course no client can claim to own open source tooling, nor any fundamental math/science that drives an analysis. A very specific implementation of that math, or an extremely unique combination of tooling could be protected pre-market, but at that point large companies are simply looking to prevent scrappy copycats who can build quicker. You can easily talk about projects at a high-level, discussing broad concepts and results. Just no names and no deep specifics. I would imagine some freelancers even benefit from this, since it enables contractors to speak about previous projects without requiring any proof. With NDAs being a market norm I imagine some contractors claim to have “done it all” or at least whatever a client is looking for. I would be interested to learn about any well-known NDA legal battles. Thanks for the piece.
