Unidy is the Fan Identity Platform built specifically for professional sports clubs, leagues, and federations. Unlike generic SSO / CIAM tools designed for any industry, Unidy is purpose-built for sports: it unifies fragmented fan data across ticketing, e-commerce, membership, and content into a single identity layer, then activates that identity to drive measurable commercial outcomes.
Clubs use Unidy to convert anonymous fans into known, addressable profiles (Valuable Connections), replace outdated systems like plastic membership cards with digital identity and access management, and create progressive identity journeys that move fans from a simple newsletter signup to a full account (Newsletter2Account) without friction.
A core differentiator is Unidy's frontend SDK (@unidy.io), which lets clubs with no in-house development resources integrate modern login, registration, and account experiences directly into their existing websites and apps. This removes the technical barrier that normally keeps clubs locked into legacy systems.
Proven results include HSV, where Unidy enabled over 500,000 activatable fan profiles, 1.8 million opt-ins, a 70% social-to-owned conversion rate, and integration across 12+ services. Other reference customers include Preußen Münster, FC Köln, SFL, and the Belgian Pro League, where Unidy is rolling out as shared identity infrastructure across multiple clubs.
Unidy's category is not "login provider." It is commercial infrastructure: identity that clubs use to know their fans, activate them, and turn that relationship into revenue.
As a partner, Unidy brings deep specialization in sports fan identity, a vertical that generic CIAM and IAM vendors (such as Auth0, Cidaas, or KORE) do not address with the same depth. Clubs, leagues, and federations choose Unidy because their fan data is fragmented across ticketing, merchandising, and membership systems, and because most clubs do not have dedicated development teams to build and maintain custom identity solutions.
Through this partnership, joint customers gain access to a frontend SDK that integrates directly into existing club websites and apps, role-based access control suited to multi-club and league-level structures, and a proven activation model (Collect, Connect, Convert) that turns passive fans into known, revenue-generating profiles. Unidy's team works closely with partners on integration scoping, technical onboarding, and go-to-market alignment for sports-sector accounts.
Clubs collecting fan data separately across ticketing, e-commerce, and membership systems can connect all of it through Unidy's identity layer. HSV used this approach to build over 500,000 activatable fan profiles and 1.8 million opt-ins.
Clubs with large social followings but limited direct fan data can use Unidy's progressive identity model (Newsletter2Account) to move fans from anonymous social engagement to known, addressable accounts. HSV achieved a 70% social-to-owned conversion rate this way.
Clubs without in-house development resources can use Unidy's frontend SDK (@unidy.io) to integrate registration, login, and account management directly into their existing website or app, removing the technical barrier that normally locks clubs into legacy systems.
Leagues and federations managing multiple clubs can deploy Unidy as shared identity infrastructure, giving each club its own branded experience while centralizing identity and access management.
Clubs that have collected fan data but struggle to activate it commercially can use Unidy to connect identity data to ticketing, merchandising, and membership offers, turning passive fan relationships into a measurable revenue channel rather than just a login system.
Clubs still running physical membership cards (a clear sign of fan data silos) can digitize the entire membership lifecycle through Unidy, cutting production and logistics costs while giving fans a unified digital identity. Preußen Münster used this to drive measurable savings on card production and administration.
