BERLIN (Reuters) - A blank cheque acquisition company sponsored by the founders of investment fund 468 Capital said on Tuesday it would float on the Frankfurt Stock Exchange with a view to acquiring a technology company. 468 SPAC I SE said it was seeking to raise 300 million euros ($358 million) and looking to buy a business involved in marketplaces, direct to consumer, or software and artificial intelligence. The first special-purpose acquisition company to float in Frankfurt, Lakestar SPAC I SE, launched earlier this year with the backing of German venture capitalist Klaus Hommels.
