This is a role for someone who combines strategic thinking, strong financial acumen and real operating experience .

You will work closely with Partners and founders, taking ownership of new business opportunities from an early stage: shaping the initial thesis, assessing the market opportunity, building the business case, defining the go-to-market strategy and helping turn an idea into a scalable company.

We are looking for someone who is comfortable moving between strategy and execution — able to challenge a business model or discuss a financial plan, but equally motivated to get close to the market, customers and founders and make things happen.

What you'll do

- Own and develop new venture opportunities , from initial market thesis through validation and launch.
- Assess new markets, business models and emerging trends, translating insights into actionable business opportunities.
- Build and challenge business cases, financial models, unit economics and growth scenarios .
- Design and develop go-to-market strategies , including positioning, pricing, distribution, partnerships and market-entry approaches.
- Work closely with founders and management teams on strategic priorities, growth opportunities and key business decisions.
- Monitor business performance and identify the key KPIs and value drivers behind each venture.
- Prepare and present strategic recommendations and investment materials to Partners, founders and other senior stakeholders .
- Support fundraising, investment processes and other relevant corporate transactions when required.
- Build relationships across the Spanish startup and venture capital ecosystem , identifying opportunities, talent, partners and relevant market insights.
- Act as a senior sparring partner while remaining sufficiently hands-on to move projects forward autonomously.

What we're looking for

- Around 6–8 years of relevant professional experience , with the maturity and judgement to operate confidently with founders,



Partners and senior stakeholders.
- Strong track record within the startup/scale-up ecosystem, Venture Capital, venture building, strategy or other highly entrepreneurial environments .
- Particularly relevant experience could come from roles such as Strategy & Operations, Business Development, Partnerships, Expansion, Go-to-Market, New Ventures, Chief of Staff or General Management .
- Demonstrated experience building, launching or scaling businesses, products, markets or strategic partnerships .
- Strong strategic and analytical capabilities combined with solid financial acumen .
- Ability to independently structure ambiguous problems and turn early-stage ideas into clear hypotheses, business cases and execution plans.
- Strong understanding of go-to-market and business-building dynamics .
- A relevant network and strong knowledge of the Spanish startup and VC ecosystem .
- Entrepreneurial mindset: comfortable with ambiguity, fast-moving environments and switching between high-level thinking and hands-on execution.
- Excellent communication and stakeholder-management skills, with the confidence to interact at founder and Board level .
- Fluent Spanish and English are mandatory.
- Based in Barcelona or willing to relocate.

The kind of profile we have in mind

- You may currently be working in a high-growth startup or scale-up , helping launch new markets, build partnerships or define growth strategy.
- You may come from a VC or venture-building environment , but have always been particularly close to portfolio companies and the operational side of building businesses.
- Or you may have developed a strong strategic and financial foundation earlier in your career and subsequently moved closer to entrepreneurship and company building .

What matters most is the combination:

Strategic thinking + financial sophistication + operating experience + entrepreneurial mindset.

You should enjoy both thinking about what should be built and getting involved in actually building it.
