Top Artificial Intelligence Startups in California, US

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.

SCARCE builds the tokenization infrastructure that licensed issuers operate on, and never owns real estate.

AgentShelf helps businesses build, run, and manage specialized AI agents without writing code or losing track of model costs. Most companies start using AI with one-off chatbots and disconnected API experiments. Before long, they run into two common headaches: unpredictable LLM bills and no clear way to control what tools or data those models can touch. AgentShelf solves this by giving teams dedicated workspaces for each job, approved business context, and pre-built workflows, like AI Front Desk for website visitor intake and customer questions. Under the hood, AgentShelf acts as the operational guardrail. It includes a built-in LLM gateway with strict budget caps, prompt versioning, access boundaries, and end-to-end usage logs. Teams can test and swap models freely, automate everyday business tasks, and scale their AI usage with clear visibility into what’s running and what it actually costs.
