I run a consulting firm.

Get one client. Do an amazing job. Use that to tell other clients what you do.

Be specific. Most people outside tech have no idea how it works. Tell them what they will get.

Increased sales, reduced costs, better productivity. Whatever it is you do, forget about the tech and talk about the benefits.

Get your elevator pitch right. Mine is "I help businesses fix their procedures". People then say "You know, I could introduce you to my friend...."

Business first, tech last.
