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).

👉 Goal: partners spend 90% of their time with founders. You handle the rest.

Mission 3: Develop the Sprint Program

Make Hexa Sprint the most visible and magnetic accelerator in Europe.

• Build and animate the European Sprint community (founders, partners, alumni, experts).

• Own program visibility: content, events, narrative, PR moments.

• Turn every vertical launch into a signal for the ecosystem.

• Attract the best European founders to Sprint.

👉 Goal: when a top European founder thinks "accelerator", they think Hexa Sprint.

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.

What Success Looks Like (6–12 months)

• A partner can launch a new vertical 2x faster.

• 80% of repetitive ops are automated by agents.

• Every startup follows a clear, dynamic Sprint journey.

• Partners spend 90% of their time with founders.

• The European Sprint community becomes a real magnet for top founders.
