AI-powered talent marketplace connecting experts with frontier AI work
Machine-learning models screen and match candidates to remote roles in hours rather than weeks, based on skills, experience and availability.
AI-driven interviews and assessments validate professional expertise before experts are surfaced to hiring partners.
Experts work on flexible, remote projects with rates reported to average around $90 per hour and fast, recurring payouts.
Mercor collaborates with enterprises to design benchmarks such as legal, accounting and software-engineering evaluations for AI agents.

Build hyperrealistic voice agents on any AI stack, then run them on real phone calls
Abstracts speech-to-text, text-to-speech and LLM calls so you can swap vendors such as different STT, TTS and language model providers without rewriting your call flow.
Handles inbound and outbound phone calls with number provisioning, call creation, recording retrieval and CDR-style usage endpoints exposed through a documented REST API.
Register webhooks and self-contained actions so an agent can look things up, transfer a caller, or trigger work in your backend mid-conversation.
Supports streaming or turn-based conversation modes, endpointing and emotion tracking, plus browser and meeting-based interfaces beyond pure telephony.
