It may seem odd that Yuri Milner's Moscow-based internet investment company, which this week paid $200m (£123.6m, €141.6m) for 2 per cent of social networking phenomenon Facebook, did not have its own website until last week.
But Mr Milner, whose Digital Sky Technologies has amassed $1bn worth of stakes in 30 companies across eastern Europe, finds that disclosures undercut his negotiating position. "Every time we wanted to buy something, they looked at our past deals and the price went up," Mr Milner said during a series of interviews at a technology conference in Carlsbad, California.
