Who we are

Our Story.

The origins of Mersenne date back to 1996 when our founder started Prime plc, (www.primeplc.com) which became the UK’s leading healthcare developer, having delivered well over 100 projects worth over £1billion across the UK and Ireland.

Mersenne was established as an entirely separate company in 2014.   Initially purely focussed on building up a commercial investment portfolio, but with a background in development, we soon found that there was a gap in the market to provide development funding for the rapidly growing drive-thru and convenience store sectors.

Our first project was a Waitrose convenience store in Bromsgrove, closely followed by a Costa drive-thru in Peterborough…and the rest is history! See our case studies here.

Our Story

What’s in a Name:

People often ask where the name Mersenne came from. The answer is there is a Prime Number association with all the companies our founder started:

Prime Not only a Prime Number, this brand name was chosen due to its association with primary healthcare, which is the sector within which GP Surgery projects sit.

Mersenne is a rare form of prime number named after Marin Mersenne, a French friar from the 17th century.

Marrakushi (one of our investment funds) was a Moroccan mathematician of the 13th century also associated with early writings on prime numbers.
