Description
WHAT WE’RE BUILDING? The last major technological shift - the rise of the consumer internet - created LinkedIn as the networked winner in recruitment. The next great shift is here. AI is transforming how people and companies connect and it will redefine the global labor market. At Jack & Jill, we are building the company that leads this transformation. We’re 9 months old, have released two agentic products (Jack and Jill), have built a brilliant team of Europe’s best engineers, operators and ex founders, are run rating over £1m revenue and have raised $20M, led by tier-1 VC Creandum (Lovable, Spotify, Black Forest Labs, Bolt) Read more on TechCrunch. https://techcrunch.com/2025/10/16/jack-jill-raises-20-million-to-bring-conversational-ai-to-job-hunting/ In the coming years, every knowledge worker will have an AI agent managing their career, and every company will have an AI agent helping them hire. By connecting those agents, we’re building a new infrastructure for the future of the labor market itself. If that vision excites you, come help us build it. MEET JACK & JILL We are not putting a thin AI layer on broken processes. We are rebuilding from first principles with two dedicated agents who work for their users: - Jack, for candidates: An always-on career co-pilot. Jack starts with a deep conversation to understand who you are and what you really want. He provides market insights, coaching, and companionship. - Jill, for companies: A true AI talent partner. Jill goes far beyond a job description to deeply understand your company, your culture, and the real context behind a role. She sources candidates, reviews inbound applicants, conducts first-pass screening calls, and acts as a strategic thought partner. Jack & Jill will not just disrupt the existing recruitment software market, but also the 10x bigger recruitment services market. WE’RE MOVING AT BREAKNECK SPEED We’re 9 months old, and already built two remarkable products, have 100,000+ candidates using Jack, hundreds of paying customers signed up to Jill and built a spectacular early team. The technology is ready and 10x better than the status quo – we need to build and execute at a relentless speed to build on this early momentum and bring it to the world as fast as we can.
