There are only six useful colors.
The first: These are the ultimate in capital-intensive enterprises. Musk announced SpaceX’s intention to build 10,000 fully reusable rockets, each over 400 feet tall. At a cost that Payload Research estimates at $35 million each, that’s $350 billion in cash for the likes of krypton-gas burners, solar arrays, and stainless steel alloy. xAI is a major builder of high-cost data centers than run such products as its Grok chatbot. In 2025, it reportedly burned through $8 billion in cash, primarily to fund such behemoths as its $20 billion “MACROHARDRR” facility in Mississippi. The upshot: These aren’t low investment software plays that if successful, could easily post 35% net GAAP margins. In general, it’s extremely rare for “manufacturers,” whether it’s in aircraft or data generators, to achieve such lofty levels of profitability.

Use CasesThe original version of SpacetimeDB was developed as the backend of an MMORPG (a real game that you can play in Steam right now). That seems fair to me. I think all the technical choices in the database fit this use case. You can asynchronously flush to disk a WAL entry that says that xXxPussyHunter420xXx has looted [Thunderfury, Blessed Blade of the Windseeker]. 50ms of delay is OK here. He’ll get upset if the instance crashes just right then, but he’ll get over it.
