Hexa
Paris, France
Posted on Jun 25, 2025
Founded in 2011 as eFounders, Hexa is a startup studio that has launched over 40 companies with a combined valuation of over $5 billion, including Aircall, Spendesk, Front, Swan, Yousign, Upflow - and more. We are passionate about B2B software, particularly SaaS, fintech, AI, and Healthtech.
At Hexa, we launch startups from 0 to 1—again and again. But ideas and capital aren’t enough. We need people who build fast and make it resonate!
That is why we're looking for a Head of Tech & Dev Advocate to join our team.
This role is a unique blend of strategic prototyping and tech evangelism. You’ll help shape how we build—and how we tell the story.
- You’ll turn bold ideas into testable products, using the latest tools and frameworks.
- And you’ll turn what we build into influence, through content, community, and visibility.
It’s 50/50: one feeds the engine, the other builds the brand. You're not behind the scenes—you’re shaping both the product and the narrative!
1️⃣ Build — Prototype at speed (50%)
- 🎯 Turn early ideas into tangible startup prototypes
- You’ll work closely with our Partners and PMs to challenge ideas, structure early-stage projects, and, occasionally, prototype them when it creates strong leverage.
- Your main focus: coach, accelerate, and de-risk early product thinking—more than building every prototype yourself.
- Use AI tools, no-code/low-code, and fast frameworks.
- De-risk ideas, generate conviction, attract Founders.
- 🎯 Build internal tools to empower Hexa
- Create products that help Hexa Core team build faster and smarter.
- This is where you’ll be most hands-on: you’ll build internal products that empower the whole Hexa ecosystem to move faster and smarter.
- Think AI ideation tools, onboarding flows, dev kits, reusable components—and beyond.
2️⃣ Evangelize — Amplify Hexa’s tech voice (50%)
- 🎯 Share what we build—and how we think
- Some of the best stories will come from what you’ve built yourself! Make Hexa’s tech vision visible and inspiring.
- Create compelling content: demos, blog posts, and talks.
- Show how we build, and why it matters.
- 🎯 Connect with the tech ecosystem
- Act as Hexa’s ambassador to top builders.
- Build presence on GitHub, LinkedIn, Discord, etc.
- Engage dev communities and open-source contributors.
- 🎯 Animate our internal tech network
- Energize the Tech Founder community.
- Foster connections among current & alumni CTOs.
- Bridge internal and external builders.
Is that you?
- You build fast — You’ve shipped real things, solo or in small teams.
- You’re fluent in code and storytelling — You prototype and pitch with equal ease (through compelling content, events, thought leadership, and deep technical expertise)
- You thrive in the unknown — No brief? No team? No problem!
- You’re plugged into the ecosystem — AI, devtools, OSS—you’re part of the conversation.
- You know when to build, and when to empower others to go faster—you're a sparring partner as much as a maker.
Perks & Benefits
- Equity in every startup created
- Competitive package (Salary + profit-sharing)
- Swile (green transportation and meal vouchers), SideCare (health insurance)
