About the Company

This is an early-stage AI company founded by senior machine learning engineers from Meta, building technology designed to help enterprises become AI-first.

Their platform provides a foundation layer for enterprise AI – helping companies understand how their operations work, identify opportunities for automation, and enable AI agents to operate effectively within complex and constantly changing business environments.

They have already built strong early traction, reaching approximately £500k ARR within their first three months of selling, with around 9-10 enterprise customers and a pipeline worth several million pounds.

Now, they’re looking for their first dedicated commercial hire to take the business from founder-led sales to a scalable, sales-led organization.

What you’ll do:

Own the entire enterprise sales cycle – from generating pipeline and prospecting through discovery, demo, negotiation, closing, and expansion

Take ownership of the existing pipeline and close high-value enterprise deals

Build relationships with C-level stakeholders, typically engaging CEOs, COOs, CTOs, CISOs, and private equity value creation teams

Land initial pilots and drive land-and-expand growth, turning successful pilots into larger, long-term contracts

Build and own the sales playbook and outbound motion from scratch

Develop the company’s GTM strategy, including ICP, messaging, sales processes, and commercial channels

Leverage your network to create new opportunities across the UK, Europe, and US

Work closely with the founders and technical team to translate a highly technical AI product into compelling commercial outcomes

Help define the future sales organization and eventually build out the commercial team underneath you

Ideal candidates include:

• Proven Enterprise AE / Founding AE / GTM experience selling complex, high-ACV solutions
• A track record of closing large, multi-stakeholder enterprise deals
• Experience selling to C-level executives and navigating complex buying committees
• Experience with AI, agentic AI, enterprise software, or other technical products is highly valuable
• Someone who has successfully operated in a 0-to-1 or early-stage environment and understands that the playbook is not yet built
• A genuine hunter who can generate their own pipeline, not just work inbound opportunities
• Strong experience with land-and-expand / expansion revenue
• Commercially strategic, but also highly hands-on – someone who can build the strategy and execute it themselves
• Curious and adaptable: you stay close to where AI and technology are heading and can adapt your sales approach accordingly
• Comfortable challenging founders, giving feedback, and helping shape the direction of the business
• Performance-oriented and highly accountable, with the ownership mindset needed to build something from scratch

Build from zero to one – take ownership of the commercial function at a critical stage of the company

Sell genuinely transformational technology – help enterprises identify and automate complex workflows with AI

Join a company with proven early traction – ~£500k ARR, 9-10 enterprise customers, and a multi-million-pound pipeline after only three months of selling

Work directly with exceptional technical founders – the founding team has deep experience building AI products at Meta and operating at massive scale

Own global expansion – with traction across the UK and ambitions to significantly expand into the US market

Build the sales organization – create the playbook, establish the GTM motion, and eventually hire and lead the team beneath you

Move fast and have real impact – your decisions will directly shape how the company scales
