Since 2012 I’ve raised over $10 million to date for various startups. If you don’t want to be that entrepreneur staggering through your pitch it’s key to prepare a presentation deck.
If you’re not asking for money, but present potential investors a series of assumptions you want to see tested, getting funded is relatively easy. Do not try to make the perfect or a customized pitch deck. Pick a standard Y Combinator deck or use The Pitch Canvas and send test it on a couple of investors. Based on their feedback then produce a different version for each type of investor (bank, business angel or venture capitalist).
