Transaction due diligence has been an integral part of the Calash offering since its foundation over twenty years ago, with a cumulative enterprise value of advised transactions exceeding $35bn across buy-side, sell-side and restructuring mandates.

Sector-led diligence for investors and management teams

Calash works with a broad range of financial institutions — including private equity, venture capital, hedge funds, pension funds, infrastructure investors, private credit investors, debt funds and banks — as well as corporate clients ranging from start-ups to listed multinationals.

Our diligence offering reflects Calash's unique history as a consultancy founded on first-hand industry experience. We bring genuine sector intelligence to every engagement, not just process, giving clients a clearer and more grounded view of the risks and opportunities in every transaction.
