For an AI build the decisive question is what you walk away owning. The best company hands you the code and the accounts it runs on the day it ships, with no lock-in, so you can run it, hand it to your own team, or move it whenever you like. The common trap is the opposite: a vendor who hosts and holds everything, so the software works but you can never leave without rebuilding it from scratch. Lead with ownership and a lot of the field disqualifies itself.
The other tests support it. You do not need a firm that trains its own models, the frontier ones are a commodity you rent, already astonishing: AI now resolves over 70% of verified real-world software bugs (SWE-bench Verified). What you need is a company that aims them precisely, engineers a reliable system around them, quotes a fixed price in rand and then gives you the keys. With 95% of enterprise AI pilots showing no measurable return (MIT, 2025), an asset you own beats a subscription you are trapped in.
