PartnerProp Wins Top “Leader” Rating for the Fifth Consecutive Term in the Agency Management System Category at ITreview Grid Award 2026 Spring

PartnerProp, Inc. (headquarters: Chiyoda-ku, Tokyo; CEO: Takumi Inoue), a Japanese leading company that provides PRM (Partner Relationship Management) systems to help sales agencies “sell through science,” announced that it has received the highest “Leader” rating in the agency management system category at the ITreview Grid Award 2026 Spring. PartnerProp was the only product in the category to receive the top rating, marking its fifth consecutive award in the same category. The ITreview Grid Award is a quarterly award based on user reviews posted on ITreview, a review platform for enterprise IT products and cloud services. The “Leader” title is given to products that receive high evaluations in both customer satisfaction and market recognition. In the agency management system category, PartnerProp was listed in first place as of March 9, 2026. Its product page also shows strong ratings, with a satisfaction score of 4.9 and 35 reviews. PartnerProp has been recognized as a PRM platform that centralizes key operations required for partner marketing, including communication with partner companies, deal management, information sharing, and partner enablement initiatives. Reviews on ITreview highlight its ability to consolidate partner communication and performance management that often become scattered across multiple tools, visualize partner activity and deal progress, and track training content views and enablement status. These capabilities are important for systematizing partner marketing operations that can otherwise become dependent on individual staff members. Users have also praised PartnerProp for its intuitive interface and its support structure for implementation and ongoing operations. Actual reviews include comments such as: centralized management helped reduce communication costs; contract status, deal progress, and training content viewing status are consolidated into a single platform; and the UI is intuitive with strong support during implementation. PartnerProp said it will continue developing its product and improving customer value, not only to support the promotion of partner marketing but also to help companies establish operational foundations and improve reproducibility. PartnerProp, Inc. is a startup with the mission “Make co-creation the engine of society.” The company aims to update partner channels and lead the PRM market, which has grown into a massive global market worth 38 trillion yen, while promoting inter-company co-creation as a representative Japanese leader in the field. The company develops and provides PartnerProp, a PRM tool designed to help companies realize partner marketing. Traditional partner channels span multiple companies, making it difficult to visualize partner activities and build mechanisms for joint sales promotion. By using PartnerProp, companies can address these issues, expand partner channel performance, and ultimately drive business growth. The service is already used by a wide range of companies, from enterprises to startups, and has received a Leader rating in the PRM category on ITreview, one of Japan’s largest review sites.
