Martlet is the investment arm of the Marshall of Cambridge group, providing small (initially £10K to £100K) sums of capital for early-stage technology startups that are located in the UK, with a bias towards Cambridge and East Anglia. Martlet will almost always co-invest with angels and small seed funds, and has the capacity to follow in subsequent investment rounds. To read about the history of the Marshall Group click here. 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. We focus on companies that have completed the proof of concept stage, and usually will have achieved some sales/grant revenues. In all cases, there must be a strong and demonstrable commercial demand for the technology under development. As part of the Marshall Group (encompassing aviation, aerospace and commercial/consumer vehicles), with over £1 billion of sales, employing over 4000 people, our investees may have the opportunity to work with our operating companies. In addition to capital, we can offer support, experience and a network of contacts. Peter Cowley is the main point of contact, and a group of senior Marshall executives will assist in choosing appropriate investments. Peter Cowley is a seasoned Cambridge-based mentor and angel investor. Peter has a Cambridge University degree in Engineering and Computing Science, lived in Bavaria for five years and owns technology and construction businesses.
