Gem vs Jack and Jill, running your own pipeline or paying per hire
Gem vs Jack and Jill is a choice between doing the work and buying the result. Gem is software your recruiters run, with sourcing, a CRM and an optional ATS, priced by company size. Jill is an AI recruiter that introduces candidates from Jack's opted in network and charges when you hire.
What Jack & Jill actually is
Jack & Jill Two AI agents from one company. Jack is a free career agent for job seekers, who talk to him for about 10 minutes. Jill is the hiring agent for companies, and she introduces candidates from Jack's network who have opted in.
You give Jill a job description, notes or a conversation. She sharpens the role, maps the market and sends a short list of introductions, mostly for London and San Francisco startups.

Doing the work or buying the result
With Gem, your recruiters do the hiring and Gem makes them faster. They search, write sequences, review ranked applicants and keep every relationship on file for the next role. The cost is predictable and the pipeline you build belongs to you.
With Jill, you describe the role and she does the finding. There is no database to search and no sequence to write; the candidates arrive already interested. The trade is reach: you only meet people inside Jack's network, which today centres on two cities.
Choose Gem if, choose Jack & Jill if
Do
- You have recruiters, or will soon, and want them working from one system
- You hire across many locations, not only London or San Francisco
- You want a talent pool that stays yours after each search
- You need an ATS now, and Gem All in One can be it
Do not
- You are a Seed to Series C startup in London or San Francisco
- Nobody on the team has time to source or write outreach
- You would rather pay on a hire than commit to a subscription
- You want a handful of introductions, not a long list to work through
One senior engineer hire, two ways
- Brief In Gem you describe the person to its AI Sourcing Agent. With Jill you share the job description or simply talk the role through, and she proposes what great looks like and a rubric.
- Find Gem searches 800M+ profiles and your own CRM and returns matches with reasoning. Jill checks Jack's network for people whose stated goals fit the role.
- Engage Gem sends your multi step sequence by email, SMS or InMail. Jill makes a warm introduction to people who have already said yes to hearing about it.
- Refine In Gem you adjust the search and the Application Review criteria. With Jill you give feedback in Slack and her hiring memory adjusts the next introductions.

Frequently asked questions
Is Jack & Jill better than Gem?
They are not the same kind of product. Jack & Jill's Jill is better if you are a London or San Francisco startup with no time to source and would rather pay on a hire. Gem is better if you have recruiters who need one system for sourcing, CRM and outreach that works in any market.
How does Jack & Jill charge companies?
Jill is free to start. Its pricing page describes a success fee, set as a share of first year salary, charged only when you hire, with no subscription or retainer. Its FAQ adds that current plan details, refund and replacement terms are confirmed in your commercial agreement, and that there is no exclusivity or minimum number of hires.
Gem vs Jack and Jill pricing: which costs less?
It depends on how many people you hire. Gem is a recurring cost priced by company FTE count, with a startup programme. Jill costs nothing until a hire, then charges a fee tied to that hire's salary. For one or two hires a year Jill's model may cost less; at steady volume, compare both quotes.
Where do Jill's candidates come from?
From Jack, the free AI career agent. Jack has short conversations with job seekers, over 400,000 of them across London and San Francisco by Jack & Jill's count, and learns their goals. When they are ready, they opt in to introductions through Jill, so companies are not cold messaging strangers.
Does Jill interview candidates?
Jill's pages describe matching, a shortlist and warm introductions, plus rubrics and calibration for the company. They do not describe Jill running an interview with the candidate. Jack talks with candidates about their goals and offers them mock interview practice, which is coaching for the candidate rather than an assessment for you.
Can I use Jack & Jill alongside Gem?
Yes. Jack & Jill says there is no exclusivity or lock in, so a team can run its own pipeline in Gem and add Jill for specific roles. Jill delivers candidates through Slack, so agree who logs Jill's introductions in Gem to keep one record per person.
Does Gem work outside the US and UK?
Gem's pages do not limit it by market. Its sourcing searches 800M+ profiles, and its customers include enterprise teams on Greenhouse, Workday, Lever and iCIMS. Jill, by contrast, says it is strongest in London and San Francisco.
