Castle Island partners


We target large industrial sectors that are ripe for consolidation, where
smaller niche players operate successfully under the
price and volume umbrellas set up by much larger players.
We like value added distribution, manufacturing or service businesses that have recurring demand and customer relationships, who win based on technical expertise, customer service, speed/responsiveness and product or service quality. Often our companies' solutions are
​spec'd or engineered into OEM customers' product designs.
Initial platform companies are based in the United States or Canada and typically have between $750k and $10 million in EBITDA, although we can pursue smaller or larger opportunities where we have expertise. Add-on acquisitions for existing platforms can be smaller.
We can bring new management or back existing teams.
See below for our current target markets for new platforms as well as follow-on acquisitions for existing portfolio companies.



REPRESENTATIVE TARGET INVESTMENTS:



Pigments and Dyes



We are seeking to acquire manufacturers of colorants playing in defensible OEM market niches with at least $3 million in revenue to combine with our portfolio company Organic Dyes and Pigments (acquired in 2014). Organic operates out of two facilities in RI and SC and is seeking to add products, talent and market segments to its existing business.



Test and Measurement



We are actively pursuing acquisitions in the test and measurement space, including sensors, gauges, transducers and meters used in electrical, pressure or other industrial applications.




Flow Control



In partnership with an experienced industry executive, we are seeking to acquire profitable branded industrial pump, valve, actuator manufacturers, distributors and service centers with at least. We are particularly interested in suppliers to the HVAC, Water/Wastewater and Data Center end markets, where there is a favorable tailwind for growth.



Coatings and Laminates



Leveraging our team's investment and operating experience in textiles, home furnishings and industrial markets where coatings and lamination services are a critical part of the manufacturing process, we are seeking profitable coatings manufacturing services companies which can function as a platform to buy other businesses.

Castle Island Partners has been investing in industrial and consumer businesses since our founding in 2006. We are now exclusively focused on industrial manufacturing, distribution and service businesses with EBITDA between $750k and $10 million. At the lower of this size range, we are principally buying for our own accounts, whereas for larger deals we partner with large family offices and institutions, with whom we have collaborated in the past. We typically buy a controlling stake but are open to minority investments in companies where we have a material say and economic stake in the partnership. Our objective is to own businesses for 10-15 years. We have acquired six companies and currently have three active investments: Boston Interiors Furniture, Organic Dyes and Pigments, and ADT Pizza.
