Why this role is remarkable

• Significant financial upside with 10-15% success fee commissions and 1% founding-team equity, modeled after high-performing AI-native investment banks.
• Backed by world-class venture capital including an early SpaceX investor and the founders behind SaaS giants like Canva and Notion.
• Access to proprietary AI systems (Sage and Sterling) that handle buyer matching and CIM prep, letting you focus entirely on closing deals.

What you will do

• Own the end-to-end deal lifecycle for 5-8 sell-side campaigns, driving transactions from client onboarding through to final negotiations and close.
• Run systematic, data-driven buyer outreach campaigns and manage high-stakes relationships with strategic acquirers and private equity firms.
• Act as the primary advisor for business owners in the building services and healthcare sectors, providing investment-bank-quality guidance during their most critical transitions.

The ideal candidate

• 3+ years of M&A advisory, investment banking, or corporate development experience with a proven track record of closing middle-market or SMB transactions.
• Strong client-facing confidence with the emotional intelligence required to shepherd 50-70 year old business owners through complex, high-stakes sales processes.
• A tech-forward mindset with an appetite for using AI tools and Notion to build scalable, automated systems rather than following traditional banking legacy workflows.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
