What Big 7 Partners buys
Big 7 Partners is the private equity arm of a California family with more than 125 years in manufacturing. It used to go by Big 7 Ventures. It buys small entrepreneur and family-owned companies in basic manufacturing, transportation and logistics, and services that sell into construction. Its holdings include Bowtex and Modern Concrete, which delivers volumetric concrete to remote job sites from Elko, Nevada.
The firm takes majority stakes and writes checks of $5 million to $25 million, with more capital held back for growth. Its About page asks for revenue of $5 million to $25 million and EBITDA of $1 million to $5 million, while a second criteria page stretches that to $2 million to $40 million of revenue and $1 million to $8 million of EBITDA. It uses little or no debt and gives managers real equity incentives. With a floor of $1 million of EBITDA, a small owner can approach it directly as a new platform.

Greymont’s take
How Big 7 Partners fits a seller
Big 7 suits the owner of a small, durable industrial or construction-related business who would rather sell to a family than to a fund. It says it tries to meet a seller's personal needs as well as financial ones, and its low use of debt is unusual at this size. In the 2025 Modern Concrete deal, founder and president Scott Reutner stayed on to run the company, and the firm offers managers meaningful equity.
Its public record is short, with three businesses listed since 2022, so an owner should ask to speak with the Bowtex and Modern Concrete teams. Because the firm calls itself a private equity arm while investing family money, also ask whether it has a planned holding period and how much capital is set aside for growth after closing.
Questions owners ask
What size company does Big 7 Partners buy?
Its About page lists revenue of $5 million to $25 million and EBITDA of $1 million to $5 million, with checks of $5 million to $25 million. A separate criteria page shows a wider range, up to $40 million of revenue and $8 million of EBITDA.
Does the owner stay on after Big 7 invests?
In the Modern Concrete deal, founder and president Scott Reutner stayed in charge of operations after the sale. Big 7 takes majority stakes and says it gives management meaningful equity incentives.
Is Big 7 Partners the same firm as Big 7 Ventures?
Yes. The big7ventures.com address now redirects to big7partners.com, and a partner bio on the site still uses the older name. Press coverage of the 2025 Modern Concrete purchase also calls it Big 7 Ventures.
