## Mercor

Mercor started as an AI recruiting marketplace that used machine learning to match candidates with remote jobs faster than traditional hiring. The platform interviews and vets applicants automatically, then routes matched professionals to short-term and long-term engagements that range from software and data work to specialist expert tasks.

Over time Mercor expanded well beyond recruiting. It now positions itself around "organizing human intelligence to power the AI economy," running interfaces for frontier research, AI benchmarks and AI-agent training at scale. Its enterprise arm builds industry benchmarks with partner organizations, sells human evaluation capacity to frontier labs, and lets businesses turn their own workflow data into a new revenue stream through anonymized licensing.

Mercor reports hundreds of thousands of roles created, an average contracted expert rate around $90 per hour and millions in daily payouts. It has raised significant venture funding and works with leading AI labs and large enterprises, serving both experts looking for flexible paid work and companies that need human data, evaluations or AI-ready talent.

**Pricing & Plans:** Free to sign up for experts; Mercor takes no fee from talent. Enterprises and AI labs pay custom, quote-based rates for data, benchmarking and evaluation services — contact sales for details.

- **AI-powered talent matching:** Machine-learning models screen and match candidates to remote roles in hours rather than weeks, based on skills, experience and availability.
- **Automated expert vetting:** AI-driven interviews and assessments validate professional expertise before experts are surfaced to hiring partners.
- **Paid expert engagements:** Experts work on flexible, remote projects with rates reported to average around $90 per hour and fast, recurring payouts.
- **Industry benchmark building:** Mercor collaborates with enterprises to design benchmarks such as legal, accounting and software-engineering evaluations for AI agents.
- **Enterprise data monetization:** Businesses can license anonymized workflow data to Mercor, with automated masking of sensitive identifiers and full control over what is shared.

**Strengths:** Fast, AI-driven matching that shortens time-to-hire dramatically; High reported pay rates and quick, frequent payouts for experts; Broad scope beyond recruiting — benchmarks, evals and data monetization; Works with major AI labs and enterprises, signaling strong credibility

**Limitations:** Enterprise pricing is quote-only, so costs are not transparent upfront; Work is project-based and may be irregular for some experts; Availability depends on demand from AI labs and enterprise partners

## SourceBae

SourceBae positions itself as an AI workforce platform, and its offering has evolved well past the generic "AI recruiting" label. The company now sells a managed service that supplies AI labs, robotics teams and enterprises with the human labour AI development still depends on: domain experts who write prompts and reference answers, graders who rank competing model responses, red teamers who probe for unsafe outputs, and field teams who capture real-world task demonstrations.

The expert side of the platform covers text, image, audio and video annotation with language and subject expertise matched to the task, which makes it usable for specialised verticals rather than only general web-scale labelling. Deliverables typically take the form of supervised fine-tuning datasets, human preference rankings, benchmark evaluations and safety red-team reports — the same categories most frontier labs now purchase externally.

The newer and more distinctive layer is Physical AI data collection. SourceBae organises structured capture across households, manufacturing lines, warehouses, workshops, commercial kitchens, agriculture, construction sites, laboratories, healthcare and assisted living. Typical activities include cooking, cleaning and folding for home robotics; assembly, inspection and packaging for manufacturing; and picking, placing and scanning for warehouse automation. Pricing is quoted per project, so teams start with a scoping discussion rather than a public rate card.

**Pricing & Plans:** Contact for pricing. SourceBae quotes custom rates per project based on task type, expert seniority, data modality and volume. Job seekers can apply through the site, and companies request a scoped proposal via a demo or project discussion.

- **Domain-expert training data:** Generate supervised fine-tuning prompts, reference answers, demonstrations and review rubrics with specialists matched to your subject area rather than generalist annotators.
- **Human feedback and preference ranking:** Collect comparison data on accuracy, relevance, instruction following and domain quality so models can be tuned against ranked human preferences.
- **Model evaluation, benchmarking and red teaming:** Capabilities Assessment responses against expert-defined criteria to surface errors, knowledge gaps and inconsistent behaviour, and run adversarial prompts to expose safety failures.
- **Physical AI data collection:** Capture real tasks in households, factories, warehouses, workshops, farms, labs and clinical settings to build training data for robotics and Physical AI.
- **Managed expert teams and quality review:** Stand up project-specific teams with coordinated onboarding, task allocation, review cycles and quality monitoring, rather than recruiting ad hoc.

**Strengths:** Vetted domain experts rather than generic crowd annotators; Full-stack coverage from dataset design through quality review and delivery; Rare real-world capture network for robotics and Physical AI training; Supports multilingual and multimodal annotation in one vendor relationship

**Limitations:** Pricing is quoted per project, so there's no public self-serve rate card; Heavy reliance on managed human labour means timelines depend on recruitment; Physical AI capture programmes require logistics and consent management; Not a traditional job board for finding salaried employment
