Engagement platforms (EPs) are an essential technology to enable co-creation and service innovation. Therefore, the design and governance of these platforms are receiving increasing attention in research. In this study, we aim to identify which activities and mechanisms foster engagement and which governance mechanisms are implemented to avoid harm on EPs. To this end, we conducted expert interviews with founders, CEOs, and managers of 14 personal and household-related service platform companies from the DACH region (Germany(D), Austria(A), Switzerland(CH)), to gain insights into their activities and mechanisms for creating and maintaining successful EPs. We found eight mechanisms, e.g., moderation of content, limitations of entry and certification, employed by personal EPs (PEPs) as self-regulatory mechanisms to avoid misconduct and negative experiences of actors. The identified governance mechanisms may guide the design and governing of PEPs by providing tangible examples to foster actor engagement while considering externalities on a societal and individual level.

参与平台 (EP) 是实现共同创造和服务创新的一项基本技术。因此，这些平台的设计和治理在研究中受到越来越多的关注。在这项研究中，我们的目标是确定哪些活动和机制促进了参与，以及实施了哪些治理机制以避免对 EP 造成伤害。为此，我们对来自 DACH 地区（德国（D）、奥地利（A）、瑞士（CH））的 14 家个人和家庭相关服务平台公司的创始人、首席执行官和管理人员进行了专家访谈，以深入了解他们创建和维护成功 EP 的活动和机制。我们发现了八种机制，例如内容审核、进入和认证限制、个人 EP (PEP) 将其用作自我监管机制，以避免行为者的不当行为和负面经历。确定的治理机制可以通过提供具体的例子来指导 PEP 的设计和治理，以促进参与者参与，同时考虑社会和个人层面的外部性。
