We would like to emphasize that these are examples from different areas. This means that none of these business plans as a whole provides an ideal "blueprint" for solving this task, but they can be helpful in individual points:
DigiLight Optronics GmbH - This is not a Social/ Sustainable Business Plan, but a very "normal" business plan of a technology company. However, for individual chapters (e.g. financial planning, market and competition analysis) this is a good example.
hello simple - This is also a "normal" business plan, but with a sustainable idea. Some chapters (e.g. financial planning) are unfortunately missing.
Sleep Well - This is a student "normal" business plan with a comparatively small and feasible idea.
