Founding Account Executive | Early-Stage B2B SaaS | Build Commercial strategy and function

£90k - £120k base with a double uncapped OTE and equity

We’re hiring a Founding Account Executive to build the commercial engine of an early-stage, API-first B2B SaaS company selling into enterprise customers.

This role is for someone who doesn’t just want to run a sales process but wants to design it, test it, and scale it. You’ll be the first commercial hire, working directly with the founders to shape how the business goes to market.

The product is highly technical, integration-led, and designed for modern engineering and product teams, meaning technical credibility is essential.

The Opportunity:

As the first Account Executive, you’ll be responsible for building sales from zero to repeatable motion:

• Owning the full enterprise sales cycle from first conversation to close
• Running deep, technical discovery with engineering, product, and platform teams
• Leading API-driven solution design and integration conversations during sales cycles
• Acting as the bridge between customers, founders, and engineering
• Defining ICPs, buyer personas, messaging, and qualification frameworks
• Shaping pricing, packaging, and contract structures for enterprise deals
• Closing early lighthouse customers and building a strong reference base
• Laying the foundations for a future sales team (process, tooling, playbooks)

This is a hands-on, high-autonomy role, you’ll be building while selling.

This role suits someone who’s comfortable in early-stage ambiguity and excited by enterprise complexity.

You’ll bring:

• Proven experience selling technical B2B SaaS to enterprise customers
• Strong working knowledge of APIs, integrations, and modern software architectures
• Ability to hold credible conversations with senior technical stakeholders
• Experience operating in startups or scale-ups, ideally as an early commercial hire
• A track record of closing complex, multi-stakeholder enterprise deals
• A builder’s mindset, pragmatic, iterative, and comfortable without playbooks

You’re likely not right if you need:

• A fully defined sales process
• High lead volumes handed to you
• Don't have a technical background

Why Join:



• A genuine founding role with influence over commercial strategy
• Direct access to the founder and product leadership
• An enterprise-grade product with real technical depth
• Opportunity to define how sales is done before it scales
• Competitive salary with meaningful equity participation
