If you’re an early stage startup with 5 revenue streams, I probably won’t invest because what it tells me is that none of your revenue streams is strong enough to build a billion-dollar business. Most great startups begin with one primary revenue stream that is powerful enough to take the company to IPO. Think of Facebook with advertising or Airbnb with rentals or Amazon with online shopping. They all have one dominant revenue stream. If you need multiple revenue streams to succeed, your  business is probably broken.
