The ACM Recommender Systems conference (RecSys), is the premier venue for research on the foundations and applications of recommendation. The upcoming RecSys conference will be held in Amsterdam, Netherlands, from September 27th to October 1, 2021. Moreover, the conference will count with an inclusive format that accommodates remote attendance. RecSys 2021 will continue with the conference series practice of connecting the research and practitioner communities to exchange ideas, frame problems, and share solutions.

As a business with expertise and experience with themes related to recommender systems, we invite you to become a sponsor of RecSys 2021. Your sponsorship confers three main benefits to RecSys attendees and your company. First, your sponsorship will ensure the costs of the conference remain accessible for students and improve the quality of the conference experience for all attendees worldwide. Second, as a sponsor you will have the opportunity to showcase your organization and recruit candidates in the area of recommender systems and machine-learning. Third, as a sponsor you will have the opportunity to get involved and contribute to the conference events and the RecSys community as a whole.

We offer four levels of sponsorship, and we will work with individual sponsors to help tailor their sponsorship needs to support the events, services or functions of greatest interest to them. Details can be be found in our sponsorship document. Moreover, you can contact the sponsor chairs at .
