Open innovation is a paradigm that suggests that companies can benefit from the external ideas, technologies, and knowledge, as well as internal ones, to advance their business objectives. There are several open innovation models, and some of the most used are:
Inbound open innovation: In this model, companies seek external ideas and technologies to complement their internal R&D efforts. The company scouts for promising external solutions through crowdsourcing, innovation challenges, or partnerships with startups, universities, and other firms.

Outbound open innovation: In this model, companies share their internal knowledge, technologies, and assets with external partners to create value. The company licenses its intellectual property, spinoffs a new venture, or collaborates with other firms to commercialize its innovations.
Coupled open innovation: This model combines inbound and outbound open innovation. It aims to create a seamless flow of ideas, knowledge, and technologies between the company and its external partners. The company collaborates with external partners to jointly develop new solutions or platforms, co-create new business models, and share risks and rewards.

Open innovation ecosystem: This model is a more comprehensive approach to open innovation, involving multiple stakeholders, such as customers, suppliers, competitors, regulators, and communities. The company creates a collaborative ecosystem, where all parties contribute and benefit from shared knowledge and resources. The ecosystem can be organized around a specific technology, market, or industry:
• 97% do use Venture Client (for H1 innovation goals) while the remaining 3% is planning to implement it.
• CVC is adopted by 92% of the companies (the tool is designed primarily for addressing H2 and H3 innovations).
• Innovation Outposts and Antennas are deployed in the main tech clusters by 80% of the companies.
• Intrapreneurship is adopted by 70% of the respondents and this number is expected to increase in the near future.
• M&A is used by 75% of the companies, while an additional 8% are expected to join the group of startup acquirers.
• Startup Accelerators are now used only by 61% of the companies. 11% of them are planning to dismiss (versus 6% that are planning to introduce it).
• Venture Builders are confirmed to be on the rise. 67% of the respondents are already somewhat using this tool and 22% plan to introduce it (though 11% are considering downsizing). Multiple approaches emerged from the discussion that suggest that the model is still in the early days.

Overall, companies choose the open innovation model that best fits their objectives, capabilities, and resources. The key is to develop a clear open innovation strategy and to foster a culture of openness and collaboration across the organization.

In conclusion, open innovation is a powerful paradigm that can help companies advance their business objectives by leveraging both internal and external ideas, technologies, and knowledge. As demonstrated by the survey results, companies are actively adopting a range of open innovation tools and strategies to drive innovation, growth, and competitiveness. However, to succeed with open innovation, it is essential to develop a clear strategy, foster a culture of collaboration, and choose the right tools and partners that align with your objectives and resources. Ultimately, open innovation represents a significant opportunity for companies to create value and impact in today's dynamic and interconnected business environment.
