FieldFlo: $35 Million Growth Investment Raised To Advance Project And Safety Management Innovation

By Amit Chowdhry • Oct 25, 2025

FieldFlo, a rapidly growing provider of project and safety management software for specialty subcontractors, has announced a $35 million growth investment from Mainsail Partners, a leading growth equity firm focused on vertical SaaS businesses. The funding will accelerate FieldFlo’s product innovation, expand its team, and strengthen support for subcontractors in high-risk industries across North America.

Founded by former subcontractors, FieldFlo was designed to simplify the complex world of project management, compliance, and safety documentation. The company’s cloud-based, mobile-first platform helps specialty contractors streamline essential workflows including time tracking, incident reporting, certifications, and inventory management. By replacing spreadsheets and manual processes with a single, digital system of record, FieldFlo enables field and office teams to operate more efficiently while maintaining compliance with OSHA, EPA, and state-level regulations.

The platform has quickly become an essential operational and risk management tool for subcontractors who face increasing regulatory and safety demands. FieldFlo’s system helps companies minimize on-site incidents, reduce insurance claims, and improve their underwriting profiles. Its intuitive interface and configurable workflows have earned it strong adoption among contractors seeking to modernize their operations and achieve greater visibility into safety and compliance performance.

The partnership with Mainsail Partners provides FieldFlo with both financial and operational resources to accelerate its growth. Mainsail’s extensive experience in scaling construction and field-service software companies will help FieldFlo enhance its platform’s capabilities and broaden its market reach.

In addition to the funding, FieldFlo continues to expand its suite of tools aimed at transforming safety management and operational efficiency. The company recently launched Safety Academy, a centralized hub for contractor training and certification management, and FLŌTime, a digital timesheet system that offers compliant labor tracking and verifiable proof of on-site activity. These innovations reflect FieldFlo’s mission to help contractors stay audit-ready while reducing administrative overhead.

With Mainsail’s backing, FieldFlo is positioned to continue redefining project management for specialty subcontractors, delivering solutions that enhance safety outcomes, streamline compliance, and drive productivity in some of the most demanding construction environments.

KEY QUOTES:

“Our mission from day one has been simple—to make life easier for subcontractors by eliminating the inefficiencies that slow down projects and increase risk. Coming from the abatement and demolition industry, we know how complex safety and compliance management can be. Partnering with Mainsail, who has deep experience scaling construction and field service platforms, will help us deliver even more value to our customers as we expand our platform.”

Roni Szigeti, Co-Founder and Chief Executive Officer, FieldFlo

“Specialty subcontractors face growing regulatory, safety, and documentation requirements, yet many still operate without a dedicated system of record. FieldFlo’s purpose-built platform solves these challenges with remarkable usability and depth. We’re excited to partner with Roni, Brittany, and the team as they continue to define this category.”

Tollie Brown, Principal, Mainsail Partners

“This partnership marks an exciting step for FieldFlo.
