The specialist advisory boutique Qatalyst Partners will end a record-breaking week with almost $20bn worth of deal credit under its belt, after being hired to advise UK software company Autonomy on its sale to a US rival, making founder Frank Quattrone our banker of the week.

Qatalyst Partners is acting for UK software company Autonomy on its sale to Hewlett-Packard. The US technology company said in a statement yesterday that it had agreed to acquire Autonomy for £25.50 per share in cash and that it is exploring a spin-off of its PC business. The deal values the UK group at £6.7bn ($11bn).
