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.

Episode #6 of Aperture Podcast: an interview of Adrienne Perramond, presenting BAS and her experiences, as well as other aspects of her professional career.


The new podcast episode of Nerd Entrepreneurs with Johann Schlieper, President of the Business Angels Zurich, answers some personal questions about being an investor and angel investing in general.


„Gute Business Angels sind mehr als Geldgeber“, meinte die Unternehmerin, die damals als Start up von Business Angels Switzerland unterstützt wurde und nun mit ihrem Unternehmen auf eigenen Beinen steht. Vor einem Publikum, das sich dafür interessiert sich als Business Angel zu betätigen, erzählte sie von ihren Erfahrungen mit Business Angels. Eine seltene Gelegenheit für die ebenfalls anwesenden langjährigen Business Angels, den Spiegel vorgehalten zu kriegen. „Als Start up sollte man sich bewusst sein, dass die Business Angels im selben Boot sitzen“, fügte sie an. Dies solle man nutzen und transparent sein. Fakten zu verheimlichen sei kontraproduktiv. „Business Angels sind nicht Gründer“, fuhr sie fort, „ und sie sind sich dessen bewusst.“ Deshalb sei es essenziell, die verschiedenen Standpunkte zu berücksichtigen und sich gegenseitig zuzuhören. „Nur so können beide Seiten voneinander lernen.“ Und schliesslich – so die Unternehmerin – seien Business Angels auch bloss Menschen. „Lasst sie am Erfolg teilhaben, teilt nicht nur die schwierigen, sondern auch die freudigen Momente“, schloss sie den ersten Teil. Der zweite Teil der Ansprache drehte sich um sogenannt mühsame Business Angels. Nun, den weniger positiven Eigenschaften ins Auge zu sehen, ist selten ein Vergnügen, auch wenn die Aufzählung allgemein gehalten ist. Gleichzeitig sind unterstützte Start up die einzigen, die über das Verhalten von Business Angels aus einer Aussensicht berichten können. Trotzdem mutet es etwas befremdlich an, negative Verhaltensweisen von gerade denjenigen aufgezeigt zu erhalten, die von der Risikobereitschaft und Investitionsfreude der Business Angels profitierten.
