The rise of "deep-tech" is boosting Paris's startup scene

EUROPE will never create a hub of tech firms and investors to rival Silicon Valley, many experts on entrepreneurship concur. Its markets are still fragmented along national lines, flows of capital into the region are limited and because of lingering, conservative attitudes to risk, few startups grow to rival American champions.

But some digital life does flourish, spread among cities rather than fixing in one spot.
