Who We Are
Black Walnut Advisory provides institutional-grade capital raising advisory to companies — delivered with precision and discretion.
On the investor side, the firm connects capital to curated investment opportunities across equity, hedge funds, alternative strategies, and real estate.
We build long-term relationships with our clients, grounded in trust, professionalism, and alignment of interests.
Our Approach
Comprehensive solutions with long-term partnership and execution support across the full investment lifecycle.
We advise companies from the initial decision to raise capital, through transaction structuring and execution — providing full support across complex processes including mergers, public listings, and partial or full exits.
We design bespoke investment frameworks tailored to each client — individual, corporate, or institutional — with a disciplined focus on balancing risk and return in line with each investor's risk appetite.
Direct acquisition of assets and value-add development in select U.S. markets — utilizing proprietary and investor capital, underpinned by disciplined underwriting standards.
Our Practice
Black Walnut Advisory operates across two integrated disciplines — capital markets and real estate. Each mandate is executed with the same institutional standard: rigorous analysis, decisive structuring and an unwavering focus on long-term value.
Pillar One
Our capital markets activity is built around a single principle: connecting capital to opportunity with precision and speed.
We advise and execute transactions for companies seeking access to public markets, including SPAC transactions, Initial Public Offerings (IPOs), Reverse Mergers, and Direct Listings — as well as private transactions: Private Placements and Debt Issuance.
For investment funds, we originate institutional capital across multiple strategies, leveraging a global network of over 100 financial institutions, family offices, and investors worldwide. Portfolio management represents an additional pillar — allocating and structuring capital across asset classes and geographies in line with defined return objectives and risk mandates.
Black Walnut Advisory role is limited to that of a strategic advisor and does not extend to execution, underwriting, or securities distribution.
Pillar Two
Our real estate platform operates with the rigor of a dedicated investment strategy — targeting investments in select U.S. markets, acquisition of residential and commercial assets, and value-add and ground-up development programs.
Our brokerage capabilities provide access to off-market opportunities and full representation throughout the negotiation process. Asset management and long-term property management complete the platform — ensuring alignment with investor objectives and ongoing value creation.
