How this row was decided

Every row on this map is checked by hand against the trade register and the company's own material, and placed in the sector that best describes its business or its technology. Service firms and consultancies are left out, however advanced the technology they work with — the test is where the revenue comes from. Only funding figures the company or its investor has published are shown. The full rules are on the landscape ↗
