Swiss-based 21Shares is nabbing a Vontobel banker to develop its business in Europe's biggest market.

The Zug-based start-up is hiring Marco Infuso as managing director for business development in Germany, Austria, and Switzerland, it said in an emailed statement on Wednesday. Infuso is currently with Vontobel, where he oversees business development as well, but for actively-managed certificates in the Swiss and Liechtenstein markets.

He was previously with Commerzbank in Switzerland and with Lombard Odier before that. Formerly known as Amun, 21Shares has bulked out considerably in recent months, hiring both Sina Meier to oversee its Swiss business and Lucy Reynolds as an operating chief. The fintech issues exchange-traded products underpinned with cryptocurrencies.

Co-founded by Hany Rashwan and Ophelia Snyder three years ago, 21Shares won prominent financial backing including from Adam Draper, the founder of Silicon Valley's Boost VC; Graham Tuckwell, founder of ETFS Capital; and Greg Kidd, co-founder of Hard Yaka as well as from several family offices.
