Martlet Capital is the investment arm of the Marshall of Cambridge group and has invested in more than 50 start-ups, since its launch in 2011. We provide patient capital for early-stage IP rich, B2B deep technology and life science start-ups, with a primary focus on companies based in Cambridge.


Our team is comprised of experienced investors and entrepreneurs. Initial sums of capital of £100-150K are invested to help support early-stage companies. Martlet will almost always co-invest with angels and seed funds and has the capacity to follow on in subsequent investment rounds. In addition to capital, we offer support, experience and a network of contacts.


Martlet typically focuses on pre seed and seed stage companies. Potential investees must demonstrate their potential for rapid growth and will usually possess a strong defensible position with respect to their technology, intellectual property and products. In all cases, there must be a strong and demonstratable commercial demand for the technology under development.


We have achieved several exits from our portfolio, from trade sales to global technology companies and IPO’s.


Martlet Capital is part of the Marshall Group, an ambitious privately owned company founded in 1909. Headquartered on a 900-acre site in Cambridge, Marshall has three principal arms to the business: Aerospace and Defence; Property; and Ventures.
