My company has been in brainstorming mode and I've proposed a few great ideas which have been rejected. What's my play if I wish to exit company and pursue an idea that I proposed that they've clearly rejected? No development work was ever started, only a business proposal deck.

Someone will surely warn me "They rejected it for a reason, why would you still pursue it?" but the context is that they are very risk averse and I might be able to find other investors/partners who have a different risk appetite.

I need to incorporate contract signing in my application and all the searching I've seen seems to direct me to SaaS solutions.

I'd rather not depend on a vendor for this functionality. Is there no OSS library I can use that will provide the requirements for a valid/legal/enforceable signature on a contract?
