What River Sea Network buys

River Sea Network is a New York investment firm, founded in 2020 and backed by family office money, that buys and grows service businesses in the United States and Canada. Its October 2026 overview adds industrials and niche manufacturing. For a control deal it looks for founder- or family-owned companies with $3 million to $30 million of EBITDA and puts in $20 million to more than $200 million of equity, and it is happy for sellers to keep a sizable rollover stake. It also takes minority positions in companies earning $8 million to $50 million of EBITDA, and will look at corporate carve-outs and small public companies case by case.

So far its track record is in residential services, built through add-ons. With Pearl Street Capital Partners it launched Aligned Exteriors Group, a roofing platform, in 2024, and it backed P1 Service Group, an HVAC, plumbing and electrical group that has since merged into Columbia Home Services. A smaller roofing or home services company is most likely to meet River Sea as an add-on to one of those two platforms.

Greymont’s take

How River Sea Network fits a seller

River Sea suits owners of residential roofing, HVAC, plumbing and electrical companies who want a buyer that already runs a platform in their trade. Its homepage offers three paths: sell part of the company and keep running it, take some cash now with a planned exit in three to five years, or sell outright. Owners have usually stayed on. The owner of Trinity Exteriors kept running daily operations after joining Aligned Exteriors Group, and the owners of Essig Plumbing & Heating and McHales are quoted on River Sea's site praising the partnership after the sale.

River Sea's platforms are co-owned with other investors: Pearl Street Capital Partners at Aligned Exteriors Group, and Tenex Capital Management, The Edgewater Funds and Oxbow Equity Partners at Columbia Home Services. An owner should ask which firm controls the board after closing, and how much acquisition debt the platform already carries.

Questions owners ask

What size company does River Sea Network look for?

For a control purchase, its October 2026 overview targets founder- or family-owned companies with $3 million to $30 million of EBITDA and equity checks of $20 million to more than $200 million. Minority deals start at $8 million of EBITDA.

Which industries has River Sea actually invested in?

Its platforms so far are in residential services: Aligned Exteriors Group in roofing, and Columbia Home Services, which merged with River Sea-backed P1 Service Group, in HVAC, plumbing and electrical. Its site also lists auto, environmental, IT and professional services as target industries.

Can an owner keep a stake after selling to River Sea?

Yes. Its homepage describes a partial sale in which the owner keeps a significant stake and runs the business day to day, and its overview says it welcomes sellers who want to roll over meaningful equity.
