Company mission
To build the integration infrastructure that lets AI agents act — securely, reliably, across any system.
Role
Who you are
- 2–5 years of B2B SaaS closing experience with clear evidence of overperformance and rapid progression
- Strong track record of owning revenue targets, not just supporting deals
- Experience in early-stage or fast-growing startup environments
- Experience selling dev tools, APIs, infrastructure, or other highly technical products
- Comfortable selling to engineers, CTOs, and technical founders, and running demos independently
- Exposure to AI/LLM products, agentic platforms, or meaningful hands-on experience with AI tools
- High ownership mindset, bias for action, and comfort operating with autonomy — your GTM partners are US-based, so you'll run your patch without daily oversight
Desirable
- IPaaS/integrations background, security/compliance exposure (SOC 2, HIPAA), experience selling alongside PLG motions
What the job involves
- Own ARR and pipeline targets as an Account Executive at StackOne, driving revenue growth in agentic integrations, one of the fastest-moving areas of B2B AI. You'll own the UK-EU territory — a market where StackOne already has customers, brand, and momentum — and run it with a high degree of autonomy
- Full-cycle sales ownership across inbound and outbound, selling to our three ICPs and closing flagship UK-EU accounts
- You'll partner async with our US-based CEO and Founding GTM on strategy and deals, while working from our London office alongside our CTO and the product and engineering team. If you want a territory to own rather than a playbook to follow, this is it
- Own UK-EU revenue and pipeline targets tied directly to closed ARR
- Run full-cycle sales across inbound (PLG-driven developer traction) and outbound motions
- Sell to three ICPs: AI-native startups building agents, enterprise teams embedding AI into existing products, and SaaS platforms embedding StackOne for their customers
- Execute and iterate on the UK-EU outbound motion (account targeting, messaging, sequencing, experimentation)
- Run live product demos independently and speak credibly about APIs, MCP, and integration architecture
- Partner with pre-sales engineers on deeper technical validation and enterprise security conversations
- Collaborate closely with Product Marketing to refine messaging for technical buyers
- Help build early UK-EU lighthouse accounts and expansion playbooks
- Track and report on pipeline health, deal velocity, forecasting accuracy, and win rates
Salary benchmarks
Our take
The explosion of SaaS tools has created an integration nightmare for companies. More and more B2B customers are expecting their SaaS tools to integrate with each other natively. But building and managing API connections in-house as a software vendor is time-consuming and costly, diverting teams from their core roadmap and stopping sales teams from selling.
As the next-generation integration platform, StackOne is solving the challenge of building SaaS integrations at scale once and for all. Founded in 2023 by ex-Google and Oracle executives, StackOne has seen exceptionally fast growth since its launch. With its best-in-class security and real-time architecture, the company is well-positioned to become a category leader in the API integration solutions market.
