A Proven Partner for Critical Inflection Points
In the rapidly evolving global cannabinoid market, success demands more than just capital, it requires exceptional leadership, regulatory expertise and operational precision. I provide embedded executive expertise and strategic advisory services that transform regulatory complexity into competitive advantage, so your investments are positioned to deliver whilst navigating regulatory frameworks across multiple jurisdictions.
M&A AND Strategic partnerships
Safeguarding Deal Value & Enabling Growth
The Challenge: Investors often face hidden operational risks or lack access to key market players. Regulatory liabilities, cultural friction, or closed networks can threaten to destroy deal value or stall expansion.
My Approach: Instead of just providing support, I act as an embedded operational lead. I leverage my global network to identify opportunities, detect “red flags” before signing, and actively manage the integration or partnership to ensure strategic alignment.
The Impact: Synergies Captured, Not Just Planned. Shareholder value is maximized from Day ONE by eliminating operational risks and accelerating market entry.
Scope: Commercial Due Diligence • Post-Merger Integration • Buy-Side & Sell-Side Support • Joint Venture Structuring
*I do not provide regulated financial services (e.g., underwriting, placement, or securities solicitation); licensed partners handle those activities.
Interim Executive Leadership & Turnaround
Stabilization and Strategic Realignment for Distressed Assets
The Challenge: Portfolio companies in transition often lack the operational discipline to execute strategic pivots. Without immediate hands-on leadership, these ventures risk cash-flow crises or stagnation.
My Approach: I step directly into critical roles (Interim CEO/COO) to stabilise operations and reorganise teams. I provide the decisive management required to navigate turnarounds and execute pivots from within.
The Impact: Operational Stability & Scaled Growth. Restored profitability, a reorganized team, and transparent reporting that rebuilds investor confidence.
Scope: Interim CEO/COO Mandates • Cash-Flow Stabilization • Organizational Restructuring • Strategic Pivot Execution
EU-GMP-Compliant & Operational Excellence
De-Risked Delivery of Complex CAPEX Projects
The Challenge: Constructing GMP-compliant facilities carries massive risks of delay and budget overruns. A single planning error can lead to certification denial, endangering the entire investment.
My Approach: I maintain full oversight of the lifecycle from blueprint to pre-audit. I orchestrate the collaboration between investors, architects, technology suppliers, and quality managers to ensure strict adherence to global pharmaceutical standards.
The Impact: Speed-to-Market with Full Regulatory Readiness. A facility delivered on time, on budget, and audit-ready for commercial production.
Scope: GACP/GMP Planning Oversight • Vendor Selection & Management • Construction Project Management • Regulatory Pre-Audit Preparation

Executive Leadership at Critical Inflection Points
I step into regulated cannabinoid and pharmaceutical businesses as interim CEO or COO, deal-side operator, GMP build-out lead, or strategic advisor.
Over the past decade, I have worked exclusively in the regulated cannabinoid sector: co-founding and operating ventures in Austria, Germany, the Netherlands, the UK and Uruguay (CanAdelaar B.V., Cannabeo GmbH, Wanen Ltd.); leading M&A due diligence and international commercialisation at CanAdelaar B.V.; and serving as interim CEO of Echo Pharmaceuticals.
At Echo, I led a company-wide reorganisation and reduced monthly operating expenses by 40% while maintaining EU-GMP API production.
My role goes beyond providing recommendations. I take operational responsibility for the strategy, financials, audits, teams, and delivery — and remain accountable until the plan is implemented and the organisation can sustain it.
Investors, boards, and management teams bring me in when the margin for error is small: a transaction under time pressure, a portfolio company requiring restructuring, an international expansion that must convert into revenue, or a facility that needs to achieve and maintain GACP or EU-GMP compliance.
I work across cultivation, pharmaceutical manufacturing, CDMO oversight, regulated supply chains, market entry, and M&A — combining board-level strategic judgement with hands-on execution, supported by direct working relationships with regulators, operators, investors, and commercial partners across the key markets.
I am a certified phytopharmaceutical expert, with additional qualifications in cannabis extraction, horticulture, and ISO project management.
Hubertus Rebentisch
Founder I Managing Director
Here’s what my Clients say:
Hubertus was my co-CEO when I started at Echo Pharmaceuticals. He taught me the ins and outs of Echo before moving into a more consulting role for the company. Through his extensive (and I mean Extensive) network Echo managed to acquire new clients and leads.
His thorough knowledge of the medicinal cannabis world helped me in many occasions to make quick decisions on who to collaborate with and what options I should look past.
On top of this Hubertus is a great person. He is very empathetic and considerate. I thoroughly enjoyed working with him and would advise others to do so.
Jeffrey Hooft
Site Head a.i., Novartis
Hubertus experience as a CEO across a wide array of enterprises has influenced the start-up and development of CanAdelaar B.V. and of Cannabeo GmbH in an outstanding way.
With his passionate vision for cannabis’ health benefits he is a pioneer in Austrias cannabis industry.
His extensive knowledge about clean rooms and industrial filtration systems combined with his comprehensive experience with cannabis – in plant engineering, product development and extraction processes – supplies a broad base to work with the subject in an industrial scope.
