Terac

Terac is a San Francisco-based, AI-native expert marketplace founded in 2025 by CEO Zachary Baker and CTO Jack Blair. The platform recruits, screens, and delivers verified domain experts to two kinds of clients: market-research firms running interviews / surveys / product-feedback studies (customers include Maze, Strella, Tegus, Ballpark, getWhys, and Dialogue), and frontier-AI labs needing scientifically rigorous human data for training, evaluation, and alignment. Founders describe expert labor as "the rarest resource in the world right now" and have built the company around closing the gap between companies needing specialized expertise and the qualified professionals whose knowledge "no one ever asks for." As of mid-2026 the platform has onboarded 100,000+ experts and hosts hundreds of active studies (479 at last count). The company has raised $9M and carries 5.0/5 ratings on both Trustpilot and Google, among the highest customer-satisfaction scores in the expert-research space.

Terac is a verified-expert platform, applicants are screened for domain expertise before being matched to engagements. Common contributor roles include market-research participants (interviews, surveys, product feedback), AI evaluators (response review, RLHF, safety rating), and subject-matter experts for frontier-AI training data. Eligibility is matched per study, most active openings target US, UK, and Canada-based participants with specific professional backgrounds (e.g. designers, software engineers, finance professionals, legal experts, medical practitioners). Sign up at terac.com to create a profile; the platform then sends study invitations based on your expertise, availability, and current client demand. Engagements are typically remote and asynchronous; longer-form interviews may require live video sessions in business hours.
