Three characters that would otherwise take three words. The 4 stands in for “for”, a substitution product and programme naming has used long enough that nobody stops to decode it. P4B reads as platform for business, power for business, or partners for business. Each describes a live category and each is the sort of phrase a company would otherwise spend a tagline on. The .net is the natural home for a platform or service business.

A B2B buyer doesn’t need the domain explained. They need it to sound like it belongs in their inbox alongside the other vendors, and this does, in three characters instead of a three-word phrase. O4B reads as operations for business, optimisation for business, or outcomes for business. All three are the working language of B2B software marketing, which means the name arrives already positioned rather than needing to be taught.

Logos get redrawn, taglines get rewritten, product names change. The address is the one part of a brand that doesn’t need revisiting, and a three-character address stays useful regardless of what the company becomes. M4O reads as monitoring for operations, models for organisations, or marketing for owners. The first is the most immediately commercial: observability and operational monitoring is a large, well-funded category sold to technical buyers who read compressed naming without blinking, and a three-character .

Everything a customer judges an online retailer on happens after checkout. Whether the item was in stock, when it shipped, how the return went. All of it runs on systems nobody markets and everybody depends on. Order management, inventory synchronisation, returns handling and fulfilment routing form a fragmented software market currently consolidating, with real budgets attached. O4E reads as operations for ecommerce, and also as optimisation for enterprise, which is the standing promise of B2B software generally.

What people will pass on to a friend is a higher bar than what they will rate four stars. Products built on the first standard behave differently from products built on the second, and they are worth more. This word states the higher bar. Recommendable means worth recommending, which is a judgement rather than a measurement, and it is a real dictionary term rarely enough used that nothing else claims it.
