“Securing your world through better technology.”

At Greywing, we believe in the transformative power of technology, and that information delivered at the right time can change the course of history. A lot of innovation today reaches consumers through fast-moving markets, while enterprise is often left behind.

Our team at Greywing works with partners in maritime to discover how we can do better with the help of technology. Whether it is optimizing the price and environmental impact of crew changes, or intelligently assessing a sea route for piracy incidents, we aim to make decisions easier and simpler by providing the right information.

Our technology is web-first, truly mobile and focused on user experience. The complexity of managing an entire maritime voyage - including security, crewing, flight bookings and risk mitigation - is made simple enough to be done on a phone through the Greywing dashboard.

Greywing at a Glance

  • Greywing was founded in 2019, by Nick and Hrishi who met at Entrepreneur First in Singapore.

  • The Intelligence reporting platform was released in early 2020, with an in-house intelligent routing tool and natural language processing based data aggregation to provide complete coverage of risk incidents and crew-change intelligence around the world. The tool has served over 1500 reports since inception, facilitating hundreds of crew changes and securing as many voyages.

  • The predictive intelligence tool is named CRY4 after the protein that enables migratory birds to find their homes. To date, over 100,000 ports are processed and available for routing, and over a thousand maritime risk incidents have been processed with more added every day.

  • The Greywing vessel monitoring tool - called Flotilla - was released in 2020, and now includes geofencing, real-time vessel tracking, upcoming voyage prediction, and tracks over 5000 vessels.

The Team


Nick Clarke spent four years in the Royal Marines before founding the maritime security firm Citadel in 2011, which protected commercial shipping, superyachts and offshore oil & gas projects from piracy in the Indian Ocean and West Africa. Nick ran Citadel for ten years and grew the business to over US$ 4 million in turnover. In January of 2018 he woke up one day and had the instinct to move to Singapore. In June of that year he went on a three week trip to check it out and stayed at an Entrepreneurs Hostel, Draper Start-up House on Club St. Whilst he was there he saw an old photocopied A4 print out on the notice board advertising the Entrepreneur First Incubator in Singapore. In January of 2019 he packed up his things and moved to Singapore to start the Entrepreneur First programme where he met Hrishi and Greywing was born.

Hrishi Olickel counts ten years in technology, split between consumer-centric and deep-tech industries around Southeast Asia. Three years in electronics, two years in Finance, three in Insurtech and two years in Academia, he has worked with the Singapore Exchange, Venture Capital firms in Singapore, National Geographic, and one of the largest insurance brokers in India to name a few. He has also published three papers in Computer Security and Human Computer Interaction, as well as co-authoring a patent in thermal-energy based fire detection. He has built data platforms that served over 100,000 users, and leads the technology side of Greywing.

The Technology

We currently offer the following product lines through the Greywing Dashboard:

Crew Change Management

Greywing's flagship offering, CRY4 - is a predictive intelligence aggregation and planning tool, that considers hundreds of data sources - from flight prices and visa restrictions to deviation costs and subcharters - to optimize crew changes for impact - financial and environmental. CRY4 aids crew managers and management to automate the tedium of a crew change and scale faster than before.

CRY4 Risk Reports

CRY4 allows you to bring up the latest information on maritime threats and discover mitigation measures. Clients can access voyage specific intelligence relating to piracy and vessel security to amend their voyage options appropriately to minimise the threat they might encounter by for example choosing different routes or different port calls. This information is then combined with port control information to provide intelligence on port and flight restrictions as well as crew changes.

CRY4 serves as the forward-looking part of Greywing's information offerings, allowing for predictive evaluation and look-ahead in voyages.

Flotilla Vessel Tracker

Flotilla is Greywing's approach to fleet management - a digital Situation Room for large fleet managers. We provide a single dashboard for all your vessels, with only the relevant information for each vessel highlighted in a timely manner. With Flotilla, our clients can pinpoint which vessels need their attention, and what events can happen, well in advance. We connect to all parts of our clients' internal infrastructure - from voyage planning to fuel estimation and travel management - to highlight key issues and provide a high level overview of everything they need to know.
