Onepager lets you build a simple digital summary of your startup to share with peers and investors. I was initially wary of Onepager, but their service is simple, easy to use, free for the most part, and it does a good job. They advertise your onepager to a list of investors, and while I wouldn’t expect anything from it personally, it’s thankfully not predatory like most tools that claim to involve themselves in the fundraising process.
