As soon as you capture the attention of a VC, they’re going to start performing the “due diligence” required to justify the investment. This is when the investor checks into the bold claims you have made about the size of your market opportunity and your work experience.
When getting ready to pitch VCs, founders often jump right into assembling a slide deck. I think this is a mistake. I’d suggest that you start by writing twenty headlines that sum up your startup, and only then build the slides.
Even for strong startups, fundraising is a marathon that requires near constant attention for 8-12 weeks. The process is punishing, and riskier than you might imagine. You need to prep for it as seriously as you would a race.
