About Guilded AI.

What we do

We build expert training data, expert evaluations, recurring evaluation programs, and data strategy for teams working on AI systems. The work is for domains where quality depends on judgment, credentials, context, and clear standards.

We match data users with expert contributors, help experts proactively create valuable data, and partner with organizations looking to understand and increase the value of their data in emerging data markets.

Current stage

Guilded AI is an early-stage public benefit corporation. We are building the contributor network, developing our methodology, and taking selected conversations with AI labs, enterprise AI teams, research organizations, expert communities, and data-holding institutions.

Team

Guilded AI is led by Heather Mellquist Lehto, PhD, CEO and co-founder, and Matt Prewitt, co-founder.

Heather is a mathematician and PhD anthropologist whose work sits at the intersection of complex human insight and technical production. Matt is a lawyer, technologist, writer, and longtime researcher of fair data economies, data coalitions, governance, and institutional design.

Expert network

We work with credentialed domain experts: researchers, clinicians, attorneys, engineers, academic scholars, humanists, and field leaders with rare practical knowledge.

Contributors are treated as specialists, not generic task labor. We are building processes that respect expert time, preserve contributor context, and create more meaningful leverage for data creators.

How we work

• We start with the data need, evaluation question, domain, and standard.
• We identify the contributors whose judgment fits the work.
• We design rubrics, calibration, review, and provenance around the use case.
• We prefer recurring relationships where standards and expertise can improve over time.
• We review contributor conversations personally and do not use AI-led interviews.
• Customer and partner conversations are confidential.
