Your Plan
Companies pay when they hire through Jill.
Why is Jack free?
Jack’s mission is to give everyone unimaginably good career support, not just those who’ve already made it. When Jack introduces you to a company through Jill’s network and you get hired, the company pays a fee. Career coaching normally costs $300/hour. Jack gives everyone the same support for free. No catch. No hidden fees. Completely free.

Jill is the AI agent for hiring
No. Jack is a surprisingly human and helpful AI agent, not a generic chatbot. He doesn’t just answer questions, he actively searches 15 million jobs on your behalf, takes initiative, and makes direct introductions to hiring managers. ChatGPT isn’t built for job searching and career coaching specifically, and gives generic advice. Jack knows your story and works tirelessly to move your career forward.
LinkedIn reduces you to keywords and floods you with irrelevant jobs. Jack understands what motivates you, what kind of work will actually fulfil you, and considers every single job on earth. When there’s a match within Jill’s network, Jack introduces you directly to hiring managers at roles that never make it to LinkedIn. You skip the application altogether.
No. Jack doesn’t spam you. If he brings you something, it’s because it’s genuinely unmissable. He only shows you roles that feel like real step ups, not sideways moves. You tell him yes or no, and he gets smarter about what you want with each response.
Within 10 minutes of your first conversation with Jack, you’ll see unmissable opportunities. Not 10 weeks. 10 minutes.
No. Jack works for you, not companies. It’s built into his code that he’ll only serve your best interests, never the companies working with Jill. Unlike recruiters who get paid to fill roles, Jack has zero incentive to push you toward the wrong opportunity. If something feels wrong, Jack drops it. His only focus is helping you find fulfilling work.
Perfect. Jack is built for you. The best time to look for work is when you’re happy with your job. Jack searches while you sleep, so you’re not missing out on the perfect opportunity while you focus on your current role.
409,317 professionals across London and San Francisco work with Jack. He’s made 2,500 direct introductions to hiring managers. 20 people land a career-defining job every week with Jack’s help. Jack & Jill raised $20M from Creandum (investors in Spotify, Bolt, Lovable).
Just start with a conversation and your LinkedIn profile or CV. Jack will ask you about your experience, what you’re looking for, and what matters to you in your next role. It takes about 10 minutes.
Jack isn’t replacing your judgment, he’s giving you the kind of support usually only available to executives who pay thousands for career coaches. You’re always in control. Jack works for you, not any company. It’s built into his code that he’ll only serve your best interests. He brings you opportunities and coaching, but you make every decision. 409,317 professionals already trust Jack with the next step in their career.
