On April 2, 2026, Human API, the platform backed by Delphi Ventures and other investors, launched its new mobile application for iOS and Android. The app aims to lower the barrier to participation in the emerging agentic economy, allowing individuals worldwide to earn income by providing speech data and completing tasks assigned by artificial intelligence systems.
Audio-Based Tasks: Bridging the Data Gap for AI
The app initially focuses on audio assignments. Contributors can engage in conversational prompts or read scripted dialogue aloud. These submissions provide AI labs with diverse speech samples capturing accents, intonation, and natural variations that are difficult to synthesize artificially but essential for training advanced language models.
Human API acts as an agent-native coordination layer, enabling AI systems to request human input when tasks require linguistic nuance or real-world interaction. Users browse available assignments, submit their work, and receive payments after review—creating a streamlined pipeline for validated human-generated data.
CEO: 'Anyone with a Smartphone Can Start Earning'
Sydney Huang, CEO of Human API, emphasized the global opportunity: "The Human API mobile app makes it possible for anyone with a smartphone to start earning as a contributor to the agent economy. People all over the world can monetize the skills that make them uniquely human, starting with the nuance of speech. In the process, they're supporting a scalable way for AI systems to obtain the nuanced human data they need."
Human API has raised $65 million from investors including Placeholder, Hack, Polychain, DBA, and Delphi Ventures. While audio tasks are the starting point, the company plans to expand into categories such as computer-usage data and real-world execution tasks, building a broad marketplace where humans contribute capabilities that remain difficult to automate.
