We just raised a multi-million dollar seed round. Now we're scaling.
We're looking for a Founder's Associate Intern to work directly with our co-founders for 6 months. You'll get exposure to everything - product, sales, marketing, hiring, finance, strategy. If you want to learn what it actually takes to scale a startup from the inside, this is the role.
Location: 📍Barcelona
What you'll actually do
You won't fetch coffee. You'll do real work across the business.
- Drive cross-functional projects - Work across product, sales, and customer success on strategic initiatives that matter. You'll own projects, not just tasks.
- Support the co-founders directly - Help with whatever needs doing - product decisions, sales calls, hiring, marketing, investor updates. The scope is wide because startups are wide.
- Build financial and investor reporting - Help prepare board updates, investor materials, and internal dashboards.
- Set up and track metrics - Support OKR definition, measurement, and analysis. Help us know if we're winning.
- Run market and user research - Prepare analyses that inform product roadmap and strategic priorities.
What we're looking for
Must-haves:
- Recently finished (or finishing) a Bachelor's or Master's degree
- Strong analytical skills - You can take messy data and turn it into something useful
- Comfortable with ambiguity - You'll figure things out without detailed instructions
- Self-starter who can juggle - Multiple projects, shifting priorities, tight timelines
- Excellent communication - Written and verbal; you'll interact with co-founders, investors, and customers
