    Faced with the unsustainable maintenance burden of his popular open-source Java linear algebra library, ND4J, the author founded Timefold.ai. The library's widespread use in commercial settings, coupled with the limited resources available for its upkeep through traditional open-source avenues like donations and sponsorships, led to this decision. Timefold offers commercial support and enterprise features built upon ND4J, generating revenue that directly funds the continued development and maintenance of the open-source project. This model allows the library to thrive and remain freely available, while simultaneously providing a sustainable business model based on its value.
