It isn't about the exits

Accelerators and investors care much more about getting a return rather than building a business. However that's not a luxury founders can afford.

What's the real value of your equity

There's a math behind how accelerators decide whether your start-up is worth investing. Did you run the calculation for diluting your equity?

Correlation isn't causation

What worked for Airbnb might not work for you. If the accelerator playbook was 100% full-proof, they would have been running a start-up and not an accelerator. After all, everyone's chasing a unicorn.
