In 2002 Mark O’Hare filed a public information request with the Massachusetts Pension Reserves Investment Management Board, seeking information on the performance of its private equity investments.
The state retirement fund initially fought the British entrepreneur’s move, arguing the data was a trade secret, but a state official sided with O’Hare, helping him overcome an early hurdle in his plan to build a business selling prized information about the secretive buyout sector.
The 65-year-old crystallised that bet on Monday with an agreement to sell his company, Preqin, to asset management group BlackRock in a £2.55bn cash deal that will catapult him into the ranks of Britain’s richest people.
