Hands-on support
Serial Entrepreneur | Startup Mentor | Angel Investor | Strategic Advisor
With over two decades of experience as a software engineer, entrepreneur, and investor, I’ve built, scaled, and advised ventures across multiple industries. Today, my mission is to empower entrepreneurs and CEOs to turn bold ideas into thriving businesses.
As the CEO of Build Up Lab — a venture studio and startup incubator — I work hands-on with international startups at every stage of their journey, providing strategic guidance, actionable feedback, and the network they need to succeed. I also lead innovation initiatives as Chief Innovation Officer at comOn, a digital marketing agency.
Beyond my own ventures, I serve as a mentor for leading entrepreneurial programs, including:
- Founder Institute
- EIC Women Leadership Programme
- Startupbootcamp
- Demium
- Santander X
What I bring to the table:
- Honest, constructive feedback tailored to your goals
- Strategic vision and product-market fit expertise
- A strong global network across tech and startup ecosystems
- An empathy-driven, active listening approach
- Deep experience in digital transformation and scaling operations
If you’re a driven founder seeking guidance, clarity, and momentum — I’m here to help you navigate challenges, avoid common pitfalls, and unlock your venture’s potential.

Rui is a very strong mentor for product development and sales strategy! He has development approaches that can help any startup in early stage to find the market fit and early clients. Within more then half a year with Rui we had a big turn around with Rui, secured our early partners and we start growing from here! Thanks so much!

My mentoring session with Rui was genuinely exceptional. He created a very positive and welcoming environment, and showed real interest in my idea. What stood out most was how practical and insightful his guidance was - he helped me understand how to approach and validate my idea, and shared a range of valuable free resources I can use moving forward. He also went the extra mile by spending additional time with me beyond the scheduled session, just to make sure I had clarity on my next steps. I’m really grateful for his support and would highly recommend connecting with him.
