Our Portfolio Companies

We position the best new technology startups for explosive global expansion.

…who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.

Excerpt from the speech - Citizenship In A Republic by Teddy Roosevelt,
delivered at the Sorbonne, in Paris, France on 23 April, 1910
