Key Points to Remember

  1. Data is not an end in itself, but a way to learn more quickly and make better decisions for your business.
  2. You should focus on One Metric That Matter (OMTMs) - the most critical metrics at any given moment - rather than drowning yourself in a sea of data.
  3. The metrics to be monitored evolve according to the maturity stage of the company. What matters for a startup in an empathic phase is not what counts for a scale-up.
  4. Analytics is not just the business of “data scientists.” It is a key skill for all members of a startup team.
  5. Building a data-driven culture is as important as having the right analytical tools and skills.
