About

Retired Boeing 777 Captain, Harvard student. Entrepreneurship and Real Estate are my passion. Especially guiding investors through their journeys. I have invested in real estate for over 20 years and tried most of it. Commercial, holiday rentals, long term, affordable housing, air bnb in 3 continents, 7 countries (Belgium, Spain, UAE, Indonesia, US, and France). Let's brainstorm about your deal, company, or strategy. If I do not feel adequate to help you, I will find someone who can.

How it works

From the right expert to real answers, in three steps.

Open access to leading experts

Search by topic, skill, or industry. Read their profile, check their rates, and see their availability, all in one place. No gatekeeping, no applications.

Pick your slot & pay

Choose a session length that fits your budget. Pay upfront - you get an automatic, VAT-compliant invoice. No awkward money talk on the call.

Get personalized advice

Join the video call, ask your real questions, get actual answers. No fluff, just focused expertise from someone who has been where you want to go.
