"The story of the Cappa"

Marc and Maarten Slendebroek, brothers and lovers of classical music, wanted to support JJF very much. The idea of matching old and young, and with that giving young talents a headstart in their carreer, as well as investing in and maintaining 'old' musical instruments, really appealed to them.
Together with them we went looking for an ancient violin, preferably one with Barok set-up and features. We organised a Listening Test in the Kleine Zaal of the Concertgebouw in Amsterdam where various violins from different sellers were played and listened to.
Goffredo Cappa's violin came out number one in this test. Experts in London, Amsterdam and Germany then tested this violin further and this produced a very postive judgement. The buying procedure was started and in June 2014 the Cappa violin was acquired by Marc and Maarten.
The brothers were of the same opining as JJF: an extraordinary violin such as this Cappa does not belong in a museum – it will keep its value just because it is played and used. Marc and Maarten have loaned the violin to JJF in order to have it played by one of her Talents.
And then what follows is 'the match'. Since not every violinist plays well or likes to play just every kind of violin, JJF organises auditions so as to make the right match between Talent and instrument. In September 2014 the Hungarian violinist Sergey Malov did audition and he turned out to be an excellent candidate for the Cappa violin.
Marc and Maarten not only gave a promising young musician an enormous push in the right direction with their investment but also do they contribute significantly to preserving this special instrument.


We welcome anyone who wants te support Jumpstart Jr. Foundation in one way or another. Marc and Maarten Slendebroek chose to invest in a pristine instrument, providing 'cultural dividend', but there are other possibilities we'd love to discuss. Non-tangible support (in kind), for example: the beautiful pictures of our Talents were taken by Tim Mintiens for a very friendly price; an international tax law firm provides specific support and advice, etc.

When you are a private investor of a foundation, you will benefit tax wise from your donation, because Jumpstart Jr. Foundation has an ANBI status due to our collection of 'historically significant musical instruments'.  


The Dutch Tax Authorities (Belastingdienst) have granted Jumpstart Jr. an ANBI status (Algemeen Nut Beogende Instellingen, or: Institution Aimed at the Common Good) in 2006, referring to charitable, religious, humanistic, cultural and scientific institutions whose mission and operations are deemed by the Tax Authorities overwhelmingly to serve the Common Good.

The Dutch government implements a fiscal policy that encourages the donation of funds to causes that advance the Common Good. Apart from granting tax advantages to Jumpstart Jr., ANBI status also favours Jumpstart Jr.'s Sponsors, Contributors and Patrons in countries that grant tax concessions to foreign registered charities, as well as those based in the Netherlands. Sponsors, Contributors and Patrons who have made a donation to Jumpstart Jr. may be able to deduct the amount from taxable income. For more information on ANBI:
