Historick\u00fd v\u00fdvoj a pozice na trhu<\/h3>\n

Snowflake zalo\u017eili v roce 2012 Benoit Dageville, Thierry Cruanes a Marcin \u017bukowski. Tito odborn\u00edci si uv\u011bdomili, \u017ee cloud computing sice transformuje podnikovou infrastrukturu, ale oblast datov\u00fdch sklad\u016f se nevyv\u00edj\u00ed tak, aby pln\u011b vyu\u017eila v\u00fdhod cloudov\u011b nativn\u00edch architektur. Spole\u010dnost fungovala n\u011bkolik let v utajen\u00ed (stealth mode) a zdokonalovala svou technologii, ne\u017e ji v roce 2014 ofici\u00e1ln\u011b uvedla na trh.<\/p>\n

Trajektorie r\u016fstu spole\u010dnosti je pozoruhodn\u00e1. V \u0159\u00edjnu 2020 vstoupil Snowflake na Newyorskou burzu cenn\u00fdch pap\u00edr\u016f (NYSE) v r\u00e1mci jednoho z nejv\u011bt\u0161\u00edch softwarov\u00fdch IPO v historii.
