How do you get investors to read your startup business plan? Well short of walking into their offices and holding a gun on them, there's no guaranteed way to get them to read a business plan.
There are however several ways to get them to not read your startup business plan and they include:
Send it to investors who don't invest in your space - You're a pre-revenue media entertainment startup located in Washington DC seeking seed funding and you send the plan to a later-stage investor that doesn't focus in media and entertainment. Wrong Stage. Wrong Geography. Wrong Investor.
Blind Unsolicited - Send in an unsolicited blind plan. Why waste a stamp. If you're sending in a blind, unsolicited business plan to an investor, save yourself a stamp. Just put it in an envelope, address the envelope and place it in your recycle bin. Maybe you should shred it first so no one else will find out how stupid you are.
Technology - Make it all about the tech. Tell them every thing about the inner workings of your technology and ignore why anyone would want it.
Use lots and lots of big words - Forget graphics, bullets and a narrative....
