The biggest unmet need in AI today is getting access to the right training data. Data holders often don’t know where to start and are rightly concerned about governance, intellectual property, and security implications. AI companies can spend years finding and negotiating access to the data they need. Protege is solving these problems by providing an easy-to-use platform to connect data holders with vetted data users.
