The question a founder is really asking
Founders often meet both names while looking for help hiring, because AI interviews are how people join Mercor's network. Its experts page describes a different marketplace: professionals apply, take a short AI evaluation, and are matched to paid projects for AI companies, typically lasting weeks to months.
Elly answers the founder's question directly. You describe the role on a call, Elly writes criteria and searches its database, returns about 20 ranked candidates the same day, runs structured screening interviews and schedules finalists. Elly's FAQ calls itself both a tool and a service, and its first hire is included with setup.

Elly's homepage lays out its process in 4 steps. Mercor describes no equivalent for hiring onto your team.

- Ranked list in minutes Candidates are scored on experience, credibility and fit, giving the recruiter about 20 qualified people the same day.
- Meet only the strongest Structured AI screening interviews run, finalists are scheduled automatically, and the recruiter is briefed before each call.
- Keep the system Scorecards, workflows and what Elly learned stay in the platform for the next search.

What working with each looks like
With Elly, the team's week runs through one workspace: the ATS, sourced candidates, AI interview scores and a notetaker on live calls. Ask Elly can search past interviews and decisions, so a runner-up from one search can surface for the next. Elly says it allows manual review and override of every AI suggestion.
With Mercor, a client works with a delivery team rather than a hiring tool. Its enterprise page describes engagements that map workflows, build and benchmark agents on a company's data, and keep improving them in production. The experts behind that work never join your payroll on the pages read.

Revealing a verified email or phone for a sourced candidate.
For teams that want to run their own search without a per hire fee, The Cognitive searches ~900M public profiles and reveals verified emails and phones, then runs a live AI video interview of 10 or 20 minutes. Reports give 1 to 5 scores per criterion, overall written feedback, a transcript and a recording.
