Most companies have trouble communicating who they are and what they're all about. That's normal — it's really hard to do. However, there's one easy way to improve how you talk: stop using startup jargon.
Here's a quick list of common startup jargon, and some better words to use:
Pivot “try again”
Monetize “make money”
Social graph “friends”
MVP “something people want”
Local maximum “reached a peak”
Learnings “what you learned”
Growth Hacking “marketing”
Root Cause Analysis “understand why”
Engagement “how much people care”
Not a zero sum game “everyone's a winner, baby”
Disruptive “probably not disruptive”
N.B. Eric Ries and the others who came up with these terms actually did a great job. Startup words can be really useful in the right context. Just avoid using jargon when normal speak will do.
