It’s very important to follow up after a meeting, not just because it’s the polite thing to do, but because Investors are busy people and believe it or not, you aren’t the only thing on their mind. You have to be persistent! Elizabeth Yin, Partner at 500 Startups writes that as an Entrepreneur she was afraid of bugging Investors too much but as an Investor she is so busy that she often doesn’t notice when someone has pinged her 3 times. She suggests to follow up when you say you will, then if you haven’t heard back, follow up within the week (about 3-4 days later) then about 3-4 days later. And always have a call to action so they know what it is you want them to do!
