Hmmm. I'm trying to think of cool h words.
-helm company…motto could play on steering/driving…
-Helios Company: bright sun as the logo…logo could do with burning or lighting the way
-not sure if you can have a three word, but "Hue and Cry" would be cool. It was a medieval saying that had to do with being duty-bound to find a criminal or villain.
-anything starting with "hell" : "hellborn", "hellward", "hellbound", "hellhound", "hellish", "hellion"
Some of these suck, but it's a start haha
on a lighter note: herb company, logo = leaf, slogan = too high to get hit
