Vonban Swiss: Sardegno and the Hummingbird companies

analysisHummingbird Capital Partners AG is the Swiss company CHE-280.752.556. Its founding entry was recorded on 29 December 2016 and published on 4 January 2017, with CHF100,000 capital. The notice appointed Sardegno as president and Sandra Sardegno as a board member, both with sole signature. A correction published on 9 January expressly changed the president’s first name from Antonio to Antonino. The correction supports the Antonio/Antonino name equivalence used in this dossier. The shared surname does not establish a family relationship. The retained notices do not identify Hummingbird’s shareholders; a presidential or managing-partner title is not proof of personal ownership. ¹

analysisThe 2020 founding notice for Hummingbird Services GmbH, CHE-395.004.334, names Hummingbird Capital Partners AG as holder of all 20 units of CHF1,000 each. Antonino Sardegno is managing chairman and Sandra Sardegno a manager, each with sole signature. The stated consultancy business includes corporate finance, governance and due diligence. This establishes a corporate holding in the services company. It does not establish that Antonino personally owns Hummingbird Capital Partners or that either Hummingbird company owns Vonban. ^{2 3}

analysisHummingbird Services and Vonban Swiss have used the same Zürich corporate offices at different stages. Hummingbird’s retained history records Nüschelerstrasse 31 in 2022 and a move to Talacker 21 published on 5 December 2025. Vonban’s move to Talacker was published one day earlier, and its later move to Zug was published in April 2026. The 2022 notice concerns Nüschelerstrasse, not Talacker. Shared office addresses and a shared former officer explain a connection; they do not prove a parent-subsidiary relationship or a service contract. ^{4 5 3}

analysisSardegno’s other Swiss notices record his departure as manager of Andetta Private Equity Services (Switzerland) GmbH in March 2023 and his appointment as a member of FumeX AG in July 2026 without signing authority. These are separate corporate offices from his ended Vonban presidency. The archive’s professional biographies and network lists are weaker evidence of exact mandate dates than the reproduced notices. A Fume brand job description and an office in FumeX AG need not be the same capacity. ²

analysisHummingbird’s website describes Sardegno as managing partner, Head of Europe at Bonalp Management and a director of Mauritius-based HCP Management Ltd. It describes the latter as an FSC-regulated collective-investment-scheme manager. Its client-adviser presentation also gives the BX Swiss register reference AS61372. These are attributed business descriptions. The retained page does not settle whether the client-adviser entry belongs to a particular natural person or the company, and it is not treated as a Swiss company-wide financial licence. Bonalp’s own registered-AIFM description is addressed separately. ⁶
