Industrial and technical companies lose go-to-market on communication rather than capability. The engineering is genuinely strong, the specifications are genuinely differentiated, and the website explains it in the language the engineering team uses internally. The buyer - often a procurement lead or a plant manager who is not an engineer - reads it, understands none of it, and picks the vendor whose page said the thing they were worried about.
The second failure is sequencing. A launch gets scheduled to a trade fair, four channels get switched on at once, and when nothing lands there is no way to tell which of the four was wrong. Money spent simultaneously teaches you nothing; money spent in an order teaches you something at every step.
The third is the assumption that a market you have not sold in behaves like the one you have. Different buying committee, different procurement rules, different search behaviour in a different language, different meaning attached to the same certification. Translating the existing material is not entering a market.
