Transactional platforms have emerged over the last decades as a dominant business configuration, receiving substantial attention from scholars and practitioners in several fields. Despite their pivoltal role, several transactional platforms fail in the launching phase, given the difficulties of reaching a critical mass and igniting cross-side network externalities. In this study we explore how a platform provider can introduce a collaborative framework from the earliest stages of platform development, aiming to highlight the benefits and challenges of moving towards a wider ecosystem through the involvement of other players. We introduce the role of platform enhancer, who is neither a supply side or a complementor, but a specific role aiming to support the platform provider in the launch and growth of the platform. We rely a single exploratory case study based on the Italian platform for digital identity, created and managed by the Italian Government through the support of a set of companies working as identity providers. Platform enhancers collaborate with the platform provider in the launch and development of a transactional platform, generating opportunities at both the launch and development stages, yet also substantial challenges and criticalities linked to increasing complexity, which climbs with the number of enhancers involved, producing coopetitive dynamics.

交易平台在过去几十年中已成为一种占主导地位的商业配置，受到多个领域的学者和从业者的广泛关注。尽管发挥着关键作用，但由于难以达到临界规模并引发跨侧网络外部性，一些交易平台在启动阶段就失败了。在本研究中，我们探讨了平台提供商如何从平台开发的最早阶段引入协作框架，旨在强调通过其他参与者的参与迈向更广泛的生态系统的好处和挑战。我们引入平台增强者的角色，平台增强者既不是供应方，也不是补充者，而是一个旨在支持平台提供商启动和发展平台的特定角色。我们依靠基于意大利数字身份平台的单一探索性案例研究，该平台由意大利政府在一组身份提供商公司的支持下创建和管理。平台增强者与平台提供商合作推出和开发交易平台，在启动和开发阶段都创造了机会，但也带来了与复杂性不断增加相关的重大挑战和关键性，复杂性随着涉及的增强者数量的增加而增加，产生了合作动力。
