A few observations based on having dealt with countless startups over the years from a legal perspective and otherwise:<p>1. Officers and directors owe a fiduciary duty to their companies to perform their duties in the best interests of the company and its shareholders. Divulging company confidential information such as finances easily could be construed as a breach of such duties. Thus, in any company having shareholders besides the founders, public disclosure is a step to be taken only with caution. Whatever is happy and upbeat today might be otherwise tomorrow and shareholders may be only too keen to second-guess management if they think some disclosure ultimately left the company vulnerable (e.g., by helping a competitor).<p>2. You can't ultimately raise money for your company without making disclosure of financial information to prospective investors and a company would, in my view, have potential liability risks from legacy public disclosures that might have been made before the funding itself. What if such disclosures were inaccurate, as they would be if tainted by puffing or by any other depiction of the company's situation that appeared to be accurate on the surface but was in fact misleading. In such a case, what is to prevent an investor from claiming to have relied in a material way on such information to his detriment?<p>There may be other legal risks as well. There certainly are business risks: giving competitors useful information on where to target their resources based on your numbers; giving adversaries in a lawsuit added leverage in their settlement negotiations with your company; giving potential vultures ammunition for when to close in for the kill in an acquisition (e.g., you disclose "happy numbers" in a couple of good years and then go silent when you get overextended as a company and become vulnerable).<p>In general, one of the great advantages of being a closely-held company is the privilege of keeping the financial information within a very tight-knit group inside the company. To give that up gratuitously will in most cases be a big mistake. Of course, it may make sense for some founder groups to opt for such disclosure for some of the reasons cited in the post and in this thread. But this should be the rare exception and not the rule.
