The FREE slideXchange product described below came out of Semlr, a content management platform I built years ago with a couple co-founders. While Semlr was built for specific collaboration use cases around slide reuse and content assembly, there was a subset of functionality that we felt could be opened up to anyone looking to share a deck. That's how slideXchange.com came about.
A FREE slide sharing tool for sharing a deck without sending an attachment. It's secure, keeps you in control of your IP, tracks usage, and is frictionless for the recipient (no file to download). It also allows you to promote your brand by customizing the front-page that the recipient sees when you share your deck with them.
See examples of what a shared deck looks like on www.slidexchange.com. SlideXchange is used to share investment, sales, training, and pitch decks.
