If you think sending a pitch deck to an investor before an in-person meeting is a good strategy, think again, says Alex Iskold, managing director of startup accelerator Techstars NYC.

“The main issue with a pitch deck is that it is subject to misinterpretation,” he wrote in a blog post on the topic. “Investors get a lot of decks and they tend to skim and glance over them.” He also thinks decks fail to capture the passion founders exhibit when they talk about their companies.

His argument: replace the written deck with a video pitch. To test the idea out, he had the founders from Techstars’ NYC Summer 2016 class do exactly that.

Below are the results: 15 pitch videos that were screened for investors at the accelerator’s Demo Day, which took place last Thursday.
