Accelerate your sales career at a startup.
At Jumpstart, we help ambitious salespeople land roles at the UK’s most exciting VC-backed startups and ensure they thrive in their roles.
As a Founding Sales Associate, you’ll join a startup at a critical stage, working directly with the founder and early team to build the first sales motion from the ground up. You’ll have real ownership from day one, learn at founder-speed, and play a visible role in shaping how the business grows.
Why Jumpstart?
Landing a Founding Sales Associate role through Jumpstart means more than just a job offer:
- Work with high-growth, VC-backed startups - connect directly with the UK’s most exciting startups.
- Chat directly with founders & sales leads - get fast responses and direct outreach from founders who are actively hiring.
- 1:1 interview training & support - tailored prep with startup sales leaders so you can go into every interview with confidence.
- Community & mentorship - join a network of Jumpstart alumni and mentors to help you smash targets and accelerate your career once in role.
What you’ll do:
While the exact role varies by startup, Founding Sales Associate responsibilities typically include:
- Build and own early revenue: prospecting, outreach, qualification, and follow-ups across the full top of the funnel.
- Work directly with the founder to shape messaging, ICPs, pricing assumptions, and early sales playbooks.
- Execute daily while building systems — learning from calls and deals to help create repeatable sales processes and CRM workflows.
- Experiment, learn fast, and adapt — there are no rigid playbooks; your ideas will directly influence how sales is done.
- Play a core role in a startup’s growth, where every new lead, deal, and repeat customer genuinely matters.
- Grow into more senior roles as the company scales.
