Strategic Advisory
Board level counsel on growth strategy, capital allocation, and structural decisions that shape the next decade of the business.
Advisory
The next stage of financial counsel
for businesses in hyper growth.
Bespoke strategic and business advisory for principals, founders, and family offices across Europe and the United Kingdom for companies that have outgrown their traditional accounting services.
The Practice
A senior advisory bench, retained on your behalf.
Aston Arbor is a private advisory practice working with a small number of principals and high growth companies each year. Our work begins where conventional accounting ends translating financial information into the decisions that move a business forward.
Where the subject demands specialist depth, we coordinate with third party experts on complex matters including tax restructuring, IP valuation and carve out, and liaising with HMRC and other authorities.
Fractional CFO
Senior financial leadership embedded in your team forecasting, reporting, and the operating cadence required to scale with confidence.
Capital & Transactions
Preparation and guidance through fundraises, refinancings, acquisitions, and shareholder events with institutional rigour.
Family Office Counsel
Independent advisory for principals and family offices on direct investments, portfolio companies, and intergenerational planning.
Global Delivery
Offshore Centre of Excellence
Full support for clients thinking about building an offshore Centre of Excellence for finance, operations, customer service and data analytics, primarily in India, the Philippines, Costa Rica and other hubs. From entity setup and recruitment to operating model, controls and governance. Excellent partnerships with Big 10 accounting firms internationally.
Approach
Disciplined. World Class. Resolute.
We accept a deliberately limited number of engagements so that each receives the attention of a senior practitioner. Our counsel is delivered quietly, in long form relationships built on candour and discretion.
