## 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

## Jellyfish (VibeOnly)

Jellyfish began life as VibeOnly, an AI skills assessment product for evaluating AI-native talent. The company has since repositioned around a different problem: how recruiting firms turn their best recruiters' instincts into something repeatable. The result is Amy, an AI sourcing employee that studies a firm's real hiring behavior and replicates it on new searches.

The product works from intake to outreach. Recruiters hand Amy a job order or call notes; she extracts and proposes requirements, flags gaps the brief missed (for example, whether a government role needs a security clearance), and waits for approval on each requirement. From there she sources beyond LinkedIn into projects, research, and online communities, and shows the evidence behind every match so recruiters decide who is worth submitting.

The core differentiator is learning. Amy records who gets submitted, who gets passed on, and who gets placed, and carries that pattern into the next role — even a role of a different type. Each client's requirements stay separated, and firms choose how much Amy is allowed to do autonomously versus what gets checked first. Access is via a live demo, and the application sign-in lives at recruiter.vibeonly.ai.

**Pricing & Plans:** Jellyfish does not publish public pricing. Access starts with a live demo booked through the site, after which commercial terms are handled directly with the sales team. The legacy VibeOnly free trial is no longer advertised.

- **Taste learning from real outcomes:** Amy tracks who each recruiter submits, passes on, and places, then applies those patterns to future searches instead of relying on static filters.
- **Guided intake and requirement approval:** Paste a job order or call notes and Amy drafts the requirement list, suggests criteria you may have missed, and waits for your approval before anything is added.
- **Sourcing beyond LinkedIn:** Candidates are surfaced from projects, research, and online communities, with supporting evidence for each match so recruiters can judge fit before reaching out.
- **Autonomous sourcing and outreach:** Once Amy understands your taste, she can keep sourcing and contacting candidates while your team is on calls, with configurable autonomy per workflow step.
- **Cross-role and per-client memory:** What Amy learns on one search carries into the next, including different role types, while each client's requirements remain kept separate.

**Strengths:** Learns from actual submissions, rejections, and placements rather than static keyword filters; Surfaces candidates from projects, research, and communities that LinkedIn-first searches overlook; Requirement intake is collaborative — Amy proposes, you approve before criteria are locked in; Configurable autonomy lets firms decide what runs on its own and what needs review

**Limitations:** No public pricing or self-serve plan; you must book a demo to get started; The rebrand from VibeOnly to Jellyfish can be confusing when searching for the product; Value depends on having historical recruiting data for the model to learn from; Best suited to recruiting firms and internal talent teams, not individual job seekers
