Tive makes small tracking devices that go inside shipping containers and trucks to monitor location, temperature, humidity, and theft in real time.

It is now 1300 customers across the globe. Nine of them pay over $1 million per year.
Krenar started this in his basement in 2015 because his father-in-law kept leaving the dinner table to call truck drivers.

His first customer paid $19.99 a month. Then he almost went bankrupt twice, laid off most of his team, and raised $100K at a down round just to survive. Today Tive is valued at $545 million and just crossed $100 million in annual revenue.
