Industrialization means technological progress that leads to replacement of manual labor with machines and through that the replacement of many smallscale producers with one large factory.
You can make technological progress without that, but many things tend to be simply more efficient at a huge scale. For example generating energy, a coal powerplant can’t work efficiently under ~300MW, wich means industrially produced electricity is cheaper than homemade electricity.
It’s definitely possible without industry, but there are a bunch of technologies aren’t feasible on the small scale. For example producing computer chips, the investment cost for the production line is huge, and using it to produce a single chip is just as expensive as producing a million (the material cost is neglectible, the machines are the expensive part)
