Something about this, along with all the other absurdly high private financing rounds currently taking place seems incredibly off. As an entrepreneur, I want access to the cheapest capital I can get, but at the same time in private rounds want partners who can open doors and help break down barriers. Slack is big enough now that the second part shouldn't be an issue (same with Uber, AirBnB, etc). Selling equity at these insane valuations isn't cheap because you're giving up only 5% of your company, it's incredibly expensive because you now need to grow insanely fast to justify these valuations to your investors. IPO'ing at a lower valuation is more expensive transaction-wise to do, but once you are a public company, you have access to the credit markets where you can sell bonds at 5-10% interest. Am I missing something else here, or is this what others are seeing too?
