Dockwa, a marina software provider based in Newport, Rhode Island, has announced an investment from PSG, a growth equity firm that partners with software and technology-enabled services companies. The company plans to expand into new markets, develop new products and build on its presence in the marina sector.

Founded in 2015, Dockwa provides software used by marina operators to manage reservations, contracts, payments and other day-to-day operations. The platform currently serves nearly 4,000 marinas and more than 450,000 boaters across North America.
The company expanded its platform to support a wider range of marina functions, including billing, fuel sales, merchandise purchases, electric metering and pricing for both short-term and annual stays.
Dockwa said the investment will help accelerate the next stage of its plans, including expanding module adoption within its existing operator base and extending the platform into Canada and Europe.
The company has compiled 11 years of transaction history through Marinas.com, Dockwa’s consumer marketplace, and Marine Graph, its proprietary data layer that powers its AI products. That data will support products including Telescope, a pricing and revenue intelligence tool for marinas, and Marina-X, a platform for insurers, lenders and institutional acquirers.
PSG managing director Chris Andrews and principal Chris Collins said: “We have spent considerable time evaluating software businesses across the marine and recreational ecosystem, and Dockwa stands out for its unique combination of a strong marina operating platform and scaled boater network. By serving both marina operators and boaters, the company has built a differentiated platform with powerful network effects that we believe will continue to strengthen over time. We are excited to partner with Mike and his team for the next chapter.”
Mike Melillo, co-founder and CEO of Dockwa, stated: “Dockwa was built to make it easier for people to get out on the water. What started as a simpler way to book a slip pulled us, conversation by conversation, into every part of how a marina actually runs. Eleven years on, the platform reflects that. PSG understands what we are building and why it takes time to compound. With their partnership, we can keep building the operating system this industry deserves – and get more people on the water doing what they love.”
Terms of the investment were not disclosed.
