Solomar, the investment arm of the family office of the Sonnenbergs, the Dutch family behind multi-national window blind manufacturing business Hunter Douglas, is upping its hedge fund investment allocations, according to a report by Bloomberg.

The Sonnebergs, who have a combined net worth of around $10bn according to the Bloomberg Billionaires Index, currently own 25% of Hunter Douglas having sold a controlling 75% stake in the company to Jorge Paulo Lemann's 3G Capital last year for around $5bn.

The report cites information from Solomar's website as revealing that it also plans to make selective co-investments in businesses and has started allocating to growth-oriented funds following the deal, which has “substantially“ increased the size of its portfolio.
