About
Independent advice, augmented by AI.

Altoria Advisory was founded by Jean-Baptiste Dayer, a finance professional with over five years of experience across UBS Investment Banking, Global Wealth Management, and Commercial Banking.

Our conviction: the Swiss SME market deserves M&A advisory that is both independent and technologically advanced. We combine the rigour of investment banking with the power of artificial intelligence to give Swiss buyers and sellers a decisive edge.

Altoria — from the Latin «alta» (high) — reflects our ambition to raise the standard of M&A advisory in Switzerland.
