Founding Associate - Hexa Sprint Program
About Hexa Sprint
Hexa Sprint is building a new kind of accelerator. No batches. No generic support. A partner-led, ultra hands-on model, designed to give startups 10x more chances to succeed. Each partner runs a vertical and works deeply with a small number of companies.
Defense: Guillaume Lerouge,
Energy Resilience: Maxime Brousse,
AI for Work: Thibaud Elzière.
Our ambition: become the largest accelerator in Europe, without ever diluting quality. To get there, we need a new kind of role.
The Role
We are looking for a founding Hexa Sprint Associate.
t's a hybrid role at the intersection of Product, AI and Venture, designed to give Hexa Sprint the leverage it needs to scale.
You will work directly with the partners and have 3 core missions.
Mission 1: Build the Sprint OS (Agentic Layer)
You'll design and build the internal infrastructure and the AI agents that power the entire accelerator:
Partner OS (Vertical Engine): help any partner structure and launch a new vertical, run fundraising (pipeline, follow-ups, materials), build visibility, and manage their 12 startups.
Startup OS (6-month orchestration engine): onboard every startup, structure their 6-month journey, track progress, suggest next best actions, automate reporting.
Agent Layer: build internal agents that reduce admin to near-zero, assist partners in real time, support founders with targeted insights, and automate repetitive workflows.
You'll experiment with OpenAI, Anthropic, APIs, no-code tools and custom workflows.
👉 Goal: make every partner 10x more effective and make Sprint scalable by design.
Mission 2: Support the Partners
You are the partners' right hand on everything that isn't "founder time".
Dealflow : sourcing, qualification, pipeline management.
Operations : running the machine day-to-day.
Fundraising : supporting partners on LP pipeline, materials, follow-ups.
Startup support : plugging into portfolio companies when needed (fundraising prep, GTM, hiring, ops).
Build the community : events, content.
👉 Goal: partners spend 90% of their time with founders. You handle the rest.
Profile
We're looking for a very specific type of person, and we care more about what you've built than your CV.
Experience
3–5 years of experience.
Either: Engineer with a finance / VC background, or Business profile with a strong product / tech background.
Deeply comfortable with AI: you already use it daily, build with it, and have strong intuitions about agents and automation.
Mindset
Builder — you like building systems more than making slides. You've already automated things for yourself.
Technically curious — comfortable with APIs, agents, LLMs, no-code. You don't need to be a senior engineer, but you can build.
Business sense — you understand startups, fundraising, ambition. You can translate messy reality into structured systems.
Structured thinker — you simplify complexity and design frameworks that scale.
Leverage-obsessed — you hate inefficiency. You do more with less.
Why This Role Is Unique
You won't join a team → you'll define a function.
You'll work directly with the partners.
You'll shape how dozens of startups are built across Europe every year.
You'll build the agentic backbone of the largest accelerator in Europe.
This is a founding role inside the machine.
