How does Jumpstart work?

We help ambitious commercial people, from first sales hires to ex-consultants, bankers and founders, land Commercial Associate and Founding GTM roles at the UK's most exciting VC-backed startups.

Founders pitch to you: founder videos show you the role, the team and what they need before you commit to a conversation.

Chat directly with founders and commercial leads: fast responses and direct outreach from founders who are actively hiring.

No recruiters in the middle: when the interest is mutual, we introduce you straight to the founder or hiring lead.

Community and mentorship: join a network of Jumpstart alumni and mentors once you're in role.

Startups from Seed to Series A, with around half of roles not advertised anywhere else. On average it takes about 4 weeks to land an offer, and you can run the process alongside your current role.
