Smart money for
smart innovators

Business Angels Switzerland, BAS, is an association of private individuals willing to invest time and money in small, newly–founded companies with innovative projects. We help startups to realize their potential.

What we do

BAS supports young companies and invests to take a minority stake in the companies. Startups can profit from the active role that BAS members take in the company, like unpaid consultants.

Each year BAS organises 20 dinner meetings in Zurich and Lausanne/Geneva where founders can pitch their business proposition.

Most of BAS investments receive mentoring and guidance from BAS members.
Startups benefit from the members' diverse skills across a broad spectrum of industries.
BAS members do not count their time and are happy to share their rich networks.
As a general rule, BAS invests in Swiss based startups with high growth potential. The due diligence process is very straightforward to make investing as uncomplicated as possible for angels and startups. The shortest investment decision yet took us one week.
BAS works well thanks to the exclusive and experienced nature of its members.
BAS members are generally successful founders or executives. They are experienced investors with an interest in mentoring and in investing in high-risk startups.
