Castle Wall Partners and Family Office Networks Announce Strategic Partnership
Palm Beach, FL – June 6, 2025 – Castle Wall Partners LLC ("Castle Wall"), a boutique advisory and investment readiness firm specializing in growth-stage technology companies, is pleased to announce a strategic partnership with FON, a leading network connecting family offices with premier private market opportunities.
This partnership combines Castle Wall’s hands-on expertise in venture-stage company health checks, due diligence, and strategic advisory with FON’s expansive family office community, built to identify and co-invest in differentiated opportunities across Climate Tech, Cybersecurity, Healthcare Technology, and beyond.
Through this collaboration, Castle Wall and FON will offer family offices:
Early access to high-quality, vetted investment opportunities in Seed to Series B stage companies
Enhanced diligence processes to increase confidence and streamline decision-making
Co-investment structures that align incentives, maximize risk-adjusted returns, and offer post-investment value creation support
"Family offices today demand more than traditional deal flow — they require strategic access to opportunities where execution risk has been thoughtfully mitigated and growth potential is tangible," said Vincent van Maasdijk, Principal of Castle Wall Partners. "Partnering with FON enables us to deliver on that expectation at scale, combining curated investments with hands-on strategic support for founders and investors alike."
The Castle Wall–FON partnership is structured to be highly selective, prioritizing investments where capital efficiency, operational scalability, and societal relevance align with the mission-driven goals of leading family offices.
“In today’s world of opportunity, family offices don’t have time or bandwidth to look at everything,” said Peter M. Apostol, CEO of Family Office Networks. “I am excited to announce Family Office Networks’ alignment with Castle Wall Partners as we strive to provide more value to our network and remove friction points from the deal making process.”
