Heartwood Partners Portfolio Company VITALSpace Expands Modular Platform with Acquisition of B.I.G Enterprises

Heartwood Partners is pleased to announce that VITALSpace, its modular solutions platform company, has acquired B.I.G. Enterprises, a manufacturer of custom guard booths and protective enclosures. The acquisition expands VITALSpace’s manufacturing capacity, broadens its end market exposure, and strengthens the company’s position as a leading provider of purpose-built modular environments.

Headquartered in South El Monte, California, B.I.G. Enterprises designs and manufactures custom guard booths and protective enclosures for clients across mission-critical, commercial, industrial, government, and high-security environments. Known for durable construction and flexible customization, B.I.G. brings a complementary product line and established customer base that deepens VITALSpace’s reach across both existing and new verticals. B.I.G. will continue operating from its current facility under its established brand and leadership team.

The acquisition builds on a year of significant momentum across the VITALSpace platform, which also includes Portable Solutions Group (PSG), SteelCell, and CareAffirm. Together, these four brands serve a broad set of end markets — including data centers, government and defense, commercial security, healthcare, and public safety — positioning VITALSpace as a diversified, multi-vertical modular platform with national reach.

“This acquisition is a direct reflection of the momentum we’ve built across the VITALSpace platform over the past year,” said Mike Smith, CEO of VITALSpace. “B.I.G. Enterprises brings proven manufacturing capabilities and a strong customer base that allows us to expand our capacity and better serve both new and existing customers. The combination gives us broader reach, greater scale, and the ability to deliver across a wider range of markets — from public safety and healthcare to data centers and high-security commercial environments.”

“VITALSpace is executing exactly the kind of disciplined platform growth we envisioned when we first partnered with Mike and the team,” said Demetrios Dounis, Managing Partner, Heartwood Partners. “The B.I.G. acquisition adds meaningful capacity and end market diversification to an already strong modular platform. With exposure now spanning data centers, government, commercial security, healthcare, and public safety, VITALSpace is well-positioned to capitalize on the sustained demand for specialized, purpose-built environments across multiple sectors. We see significant runway ahead.”
