In 1791 he made an agreement with the sugar refiners Van Beeftingh & Boon of Rotterdam for a venture producing maple syrup in central New York.
Gerrit Boon led the venture that failed to produce maple syrup profitably and transitioned to a land development company that established
Oldenbarneveld. The investments were reorganized as the Holland Land Company in 1795 with shares issued to the Willinks (28.6%), Pieter Stadnitski (23.2%), Jan and Nicolaas van Staphorst & Nicolaas Hubbard (21.4%), Pieter and Christiaan van Eeghen & Company (14.3%), Isaack ten Cate & Hendrick Vollenhoven (8.9%), and
Rutger Jan Schimmelpenninck, politician and legal adviser (3.8%). He joined the "Batavian Revolutionary Committee" when in February 1793 the
French First Republic declared war on
Great Britain, the
Dutch Republic. He met with
Pierre-Joseph Cambon president of the National Convention and the Foreign minister
Lebrun, discussing the future of the republic and the responsibilities of the French generals. In June 1794, during the Great Terror, he and Abbema left for Switzerland in the company of
John Skey Eustace. After the
fall of Robespierre they returned to Paris and met with
Lazare Carnot a member of
Comité du salut public and Dutch diplomats whose intention was to hasten an invasion. ; the large warehouse belonged to Van Staphorst From 1793 Van Staphorst lived at Keizersgracht 121, next to "Huis met de Hoofden". In April 1794 he bought a warehouse nearby. On 4 October he wrote to
Alexander Hamilton he was "
a partizan to the rights of man, and the principles of liberty and equality". On 6 October weapons caches at Roeterseiland and near
Bickerseiland were discovered.
Krayenhoff and
Gogel organized rifles and ammunition. Not long after, Van Staphorst publicly petitioned for revolution should either the English, retreating from Belgium, be welcomed in the city or action be taken against the encroaching French forces. Mid-October: five of them decided to hide or leave the city; Van Staphorst fled to
Kampen, perhaps to Hamburg. The six others felt obliged to their party not to evade prosecution. Pichegru began his second campaign by crossing the
Meuse on 18 October 1794. In January the
Armée du Nord liberated/occupied the whole of
Holland. Nicolaas Van Staphorst returned from Kampen and joined the
Batavian Revolution in Amsterdam. The Patriot Revolutionary Committee (with
Samuel Iperusz. Wiselius and Nicolaas van Staphorst) deemed it important to liberate an important city itself, without direct French aid, to support its claims to independent authority in the Netherlands. It, therefore, sent Krayenhoff to Amsterdam, in a French lieutenant's uniform, to organize another insurrection. On Sunday afternoon 18 January 1795 – at Daendels' instruction – Krayenhoff came to tell Amsterdam's burgomasters that they had better resign the next day. They requested general
Charles Pichegru to plant the
liberty tree on the Dam square (during extreme cold and snowy days). On 2 February he appeared in the town hall. On 23 February, he was appointed to the Finance Committee of Holland and then to the Foreign Affairs Committee. On 12 April 1796, he left the municipality. On 3 May, he was elected as a representative to the
National Assembly of the Batavian Republic. ==Van Staphorst family==
