The document discusses lessons learned from ODINE, a European Union program that provides funding and support to open data startups and SMEs. Some key lessons include: there is high demand for open data as it offers a unique value proposition; national open data ecosystems influence companies' success; defining the value of open data for solving customer problems is important early on; and various business models like freemium can be used. The program received many submissions and funded 6-month projects for ideas that mattered and were enabled by open data, showing there is potential for open data businesses.
