StarCast is building the trust, licensing, and rights infrastructure for the AI likeness economy. We enable creators to securely license AI versions of their identity (face, voice, and digital persona) to businesses while maintaining full ownership, approvals, pricing, usage rights, and restrictions. We're solving hard infrastructure problems around AI identity, consent verification, licensing, payments, authorization, and scalable AI workflows. Long term, we're building an AI Identity API and consent layer that AI platforms can use to verify whether a person's likeness is authorized before it is generated or deployed. This is a systems engineering challenge involving secure identity, distributed architectures, AI orchestration, enterprise workflows, and internet-scale infrastructure not just another AI application.
