Three characters on the .net in the X-for-Y shape. O4B reads as operations for business, optimisation for business, or outcomes for business.
All three are the language of B2B software marketing, which means the name arrives already positioned. A buyer in that market doesn’t need the domain explained; they need it to sound like it belongs in their inbox next to the other vendors, and this does, in three characters instead of a three-word phrase.
The .net carries no penalty for a business platform. Professional buyers arrive through referral, search, and outbound, not by guessing addresses, and the extension has never cost a B2B vendor a deal.
The durable argument is the same one that has held for twenty years: three-character domains are a finite, fully allocated set, new companies keep forming, and nothing in the market’s structure creates more of them.
