What We Do

Finding the signal
in every deal.

Every engagement is led, start to finish, by a Senior Partner. Our diligence teams work alongside custom AI that improves analytical rigour and sourcing reliability to deliver better diligence services in a fraction of the time.

We analyse and stress-test underlying earnings robustness and future profitability, tracing every adjustment to source. Our sector expertise combined with deep financial analysis produce rigorous red-flag reports that are configured to your needs and ready for your financing partners.

Sector expertise applied to the commercial health of a business — market and competitive landscape, revenue generation, and differentiation. We evaluate the growth plan and highlight the areas of challenge and opportunity.

A comprehensive analysis of operational soundness — cash flow, processes, functions, and performance. We identify where strengths can be maximised and where targeted improvement will increase enterprise value.

We support the integration of an acquired business and review the accuracy of information tied to your transaction — ensuring representations, warranties, and agreements have been fulfilled.

Our Technology

Automating manual work,
empowering human insight.

Our deal advisory partners are supported by custom-built agents that automate slow, manual processes and improve analytical accuracy.

  • Parses PDFs, Excel files, scanned documents, and unstructured data
  • Maps line items across periods to a unified chart of accounts
  • Automates checks for consistency across all data sources
