Our Team
We bring decades of specialist knowledge and hands-on transaction experience across the energy transition.
Having worked together for over a decade, Andreana and Bertie bring complementary expertise across investment, structuring and execution in the energy transition. Their experience spans a wide range of transactions, working with developers, investors and corporates across multiple technologies and markets.
Navexis was founded on a shared view that complex transactions benefit from independent, senior-led advice, combining deep sector understanding with a deliberate and execution-focused approach to delivery.
Bertie brings over 15 years’ experience advising on energy transition and infrastructure projects, with a focus on M&A, capital structuring and strategic advice. A Fellow of the ICAEW, he combines deep technical rigour with strong commercial judgement, developed through an early career in audit and financial analysis and more than a decade in transaction leadership roles.
Prior to co‑founding Navexis, Bertie spent over 13 years at JLL, most recently as a Senior Director, advising investors, developers and corporates on acquisitions and disposals across the energy transition. His experience spans the structuring and delivery of transactions, capital deployment strategies and commercial decision‑making across development, construction and operating assets.
Andreana brings deep, investment-led experience across the energy transition, with 18 years in finance and over a decade advising renewable energy developers and institutional investors. A CFA charterholder, she combines strategic and commercial judgement with a strong grounding in capital markets, developed through sell-side equity research and senior transaction leadership roles.
Prior to co-founding Navexis, Andreana was a Director at JLL, where she led a broad range of advisory, M&A and financing mandates across renewables and energy infrastructure for over a decade. Her background in equity research underpins a disciplined approach to investment positioning, valuation and sponsor and investor engagement.
