Juan Colomo

Juan Revuelta Colomo is a General Partner at Swanlaab Venture Factory, a Madrid-based venture capital firm he has helped build since its founding around 2013–2014. He describes himself as having 17+ years of venture capital experience in Spain and sits on the Investment Committee for the firm's Tech and Search Funds "since inception," making him one of the core decision-makers on the fund's B2B software investments.

Before moving into venture capital, Revuelta trained and worked as an engineer, holding roles at LSI Logic in Germany and Texas Instruments in France — a semiconductor and electronics background that informs his comfort with deep-tech and hard-tech companies. His investing coverage has spanned enterprise software, communications, semiconductors, information technology, and life sciences, focused primarily on innovative Spanish technology ventures.

On the academic side, he holds a Master's in Electrical, Electronics and Communications Engineering from the University of Navarra (TECNUN), an MBA from IESE Business School, and completed the Private Equity Programme at London Business School — a combination of engineering and finance education that maps onto Swanlaab's thesis of backing technically differentiated B2B founders.

At Swanlaab he is one of several fund managers (alongside Verónica Trapa, Yuval Avni, Zvi Schechter and Tal Mizrahi) under founder and managing partner Mark Kavelaars, with the firm structured around a "venture factory" model that pairs capital with hands-on go-to-market and sales-scaling support.

• Invests in B2B / enterprise software where technological innovation creates real competitive barriers ("secret sauce"), leading rounds at late-seed to early Series A.
• Typical entry ticket of €500K–€3M, with €2M–€4M kept for follow-on in later rounds; Swanlaab typically acts as lead investor.
• Beyond capital, emphasizes proactive operational support — especially go-to-market, marketing, and sales scaling — reflecting the firm's "company-building" / venture-factory approach.
• On teams: prioritizes ambitious, honest founders who are good listeners and thoughtful decision-makers, alongside large market potential and a clear competitive advantage.
• Sectors he has called attractive include cybersecurity ("Spain has world-class startups here"), AI as an instrumental/enabling layer (not a standalone differentiator), plus interest in blockchain/Web3 and quantum computing.
• In his own words: *"Spanish startups no longer have any inferiority complex when it comes to competing internationally"* — he sees Spanish founders as globally competitive and increasingly on the radar of major international VCs.
