As the entrepreneurship frenzy in the US grows it seems that more and more people are walking around talking about their “startup.” Sometimes they refer to a full time venture-backed endeavor. And sometimes it’s just a project “on the side.”

What turns a group of people into a “startup”? Do we call a group of people a startup:

  • When they have an idea and start to pursue it?
  • When they make a commitment to one to the other to find an idea and pursue it jointly?
  • When they form a company?
  • When they start building something or invest capital?

We might also ask – when does a startup outgrow the definition of “startup” and become an actual “company”? Does the startup threshold have to do with:

  • Company size (number of employees)
  • Number of customers
  • Company maturity
  • Ratio of R&D to the rest of company
  • Brand awareness
  • Type of investors who are investing (for example, private equity versus VCs)
  • Profitability

Think of many of the hot tech companies today – Jive, Yammer, Twitter, Yume, Palantir, etc. Many have large customer bases and big staffs. Few are profitable.

What do you think? Should they be considered startups?
