- This private equity firm started life ten years ago as a ‘family office’ backed by one of Europe’s most successful entrepreneurial families. In 2009 we helped uncover the new name, inspired by the nature of the business – Frog helps companies metamorphosize – as well as its cleantech/green focus and a simple desire to be different. With such a bold name we opted for a simple logotype and a monochrome palette. A small frog print is used as a secondary ‘signature’. We designed everything from the website to signage, stationery to printed collateral.Created at L&CO.
