Hatch left her post as head of retail financial services at Penrose last November, six years after founding the firm with three others. Hatch - who joined the agency this week - said she brought financial product experience to M: Communications.
'There are very few companies that can do group as well as product PR; many people can do one but not both,' she said.
Hatch arrives at M: Communications with 14 years' experience in financial services PR, having started at Hill Murray in 1991, which later became Ludgate Communications.
Also joining M: Communications as a consultant is Penrose senior account manager Tilly von Twickel.
Before Penrose, von Twickel worked with M: Communications founders Hugh Morrison and Nick Miles at Financial Dynamics.
